The results clarify dissimilarities in loy-alty building strategies, how loyalty differentially affects per-formance and word of mouth, and the consequences of study-specific characteristics.

Customer loyalty is the central thrust of marketing efforts(Dick and Basu 1994; Evanschitzky et al. 2012), and U.S.firms spend dramatically to build and manage customer loy-alty. For example, annual loyalty program outlays have grown27% since 2010 to exceed $48 billion across 2.7 billion pro-gram enrollees in the United States alone, yet less than half ofthe 22 memberships per household are active (Berry 2013).However, the financial returns of many loyalty-building ef-forts fail to meet expectations (Henderson et al. 2011; Nunesand Dréze 2006). Even though the concept of Bcustomerloyalty^ has been debated for more 60 years (Brown 1952),the mixed returns of loyalty efforts still stem, in part, fromdivergent theoretical and operational approaches, such as thevaried use of attitudinal loyalty without behavioral loyalty orthe use of modified word-of-mouth measures as proxies forcustomer loyalty (Dick and Basu 1994; Keiningham et al.2007; Oliver 1999; Reinartz and Kumar 2002). To test theconsequences of this heterogeneity empirically, we synthesizeextant loyalty research to provide parsimonious guidance toboth academics and managers seeking to understand the strat-egy → customer loyalty → performance process.

Although there is no consensus definition of loyalty, extantresearch generally agrees that it represents a mix of attitudesand behaviors that benefit one firm relative to its competitors(Day 1969; Dick and Basu 1994; Melnyk et al. 2009). Within

Page 2: Building, measuring, and profiting from customer loyaltyvariation in the conceptualization and operationalization of loyalty, which may explain heterogeneity in loyalty-related effects

this conceptual umbrella, researchers often selectively exam-ine loyalty as an attitude, purchase behavior, or multidimen-sional construct (e.g., attitudes and purchase behaviors, wordof mouth). Beyond this broad description there is significantvariation in the conceptualization and operationalization ofloyalty, which may explain heterogeneity in loyalty-relatedeffects. We map 163 studies published in marketing journalssince 1980, at the measurement item level, to capture theirheterogeneous research approaches. We then evaluate the de-gree to which this heterogeneity leads to disparate empiricalresults, by examining the structural relationships among loy-alty, its antecedents, and its outcomes according to meta-analytic data (Zablah et al. 2012). Finally, we examine possi-ble moderators of the effect of loyalty on outcomes with ameta-regression (Rubera and Kirca 2012).

The results of these analyses produce three main contribu-tions. First, we reconcile the differential effects of two theo-retical elements of customer loyalty—attitudes and behav-iors—according to meta-analytic results. The antecedents dif-ferentially build attitudinal and behavioral loyalty, and attitu-dinal and behavioral loyalty differentially influence manage-rially relevant outcomes such as word of mouth and perfor-mance (i.e., sales, share of wallet, profit performance, andother measurable changes). The common research practiceof using single-element measures of loyalty (i.e., only attitudeor behavior) thus leads to mixed guidance regarding the effectof loyalty on performance. This concern is especially prob-lematic when we note that most research (65% of studies inour sample) examines loyalty as an end outcome, such that itserves as a potentially misleading proxy for performance.

Second, we examine the moderating role of the measure-ment composition (e.g., ratio of attitudinal vs. behavioral loy-alty items, inclusion of word-of-mouth items) and study-specific characteristics (e.g., temporal orientation) to explainadditional variance in loyalty-related effects, using a meta-analysis of the sources of variation identified by our literaturereview and item-level coding procedure. We find for examplethat measures composed of combined attitudinal and behav-ioral items are more effective than attitude-only or behavior-only measures. Varying measurement compositions andstudy-specific characteristics of loyalty also produces differenteffects, depending on the type of loyalty and the outcome ofinterest. These analyses help clarify the heterogeneity in loy-alty effects that stem from conceptualizations and the studycontext.

Third, we provide prescriptive guidance for researchers andmanagers. In particular, we recommend strategies that buildattitudinal and behavioral loyalty, the use of loyalty itemsobtained from the measures that are most predictive of perfor-mance and word of mouth, and consideration of contextualinformation (e.g., business vs. consumer markets) that canleverage the effect of customer loyalty. We thus attempt toadd clarity to the varied conceptual and empirical findings

achieved through decades of research by answering three sim-ple but important bquestions: What is customer loyalty? (the-oretical), What are researchers doing? (measurement ap-proaches), and What actually matters? (empirical results).

Theoretical domain of customer loyalty

The rich early history of customer loyalty research allowedJacoby and Chestnut (1978) to cite more than 50 definitions ofit. Following more recent, elaborate theoretical expositions(Dick and Basu 1994; Oliver 1999), current theories mostoften delineate attitudinal loyalty and behavioral loyalty ascustomer loyalty’s primary elements (Chaudhuri andHolbrook 2001).

Loyalty as favorable attitudes and purchase behaviors

Attitudes are the first element of customer loyalty. People aremotivated information processors who use information toform their attitudes (Ahluwalia 2000; Moorman et al. 1993).Attitudinal loyalty then is a Bcognition^ or Bpleasurablefulfillment^ that favors a particular entity (Oliver 1999, p.35; see also Chaudhuri and Holbrook 2001). Strong, loyalattitudes result from systematic evaluations (Petty andCacioppo 1986) and influence many customer performance–related behaviors (Park et al. 2010; Petty, Haugtvedt, andSmith 1995). Strong positive attitudes induce Bdefensiveprocesses^ in the face of competition that cause customers toresist competitive offers, even when they are objectively better(Ahluwalia 2000, p. 230). Oliver (1999, p. 34) captures thisidea when he notes that loyalty persists Bdespite situationalinfluences and marketing efforts [that have] the potential tocause switching behavior.^

Purchase behaviors, the second element of loyalty, are alsocentral in loyalty research (Ailawadi et al. 2008; DeWulf et al.2001). Behavioral loyalty entails repeated purchases that stemfrom a conation or action orientation involving a Breadiness toact^ to the benefit of a particular entity (Oliver 1999, p. 35; seealso Chaudhuri and Holbrook 2001; De Wulf et al. 2003).Various examinations of customer loyalty focus on measuringbehaviors, such as repeated purchase behaviors, that have ob-vious benefits for a firm’s financial performance. This viewhas given rise to stochastic models of loyalty, including theuse of recency, frequency, monetary theory; churn/retention;and purchase sequences. Prior research also demonstrates thebenefits of behavioral loyalty. For example, Gupta et al.(2004) find that the impact of a 1% improvement in customerretention is five times greater than the effects of a similarincrease in margin. Yet purely behavioral approaches are oftenagnostic about the psychological processes associated withcustomer action. They ignore the real possibility that repetitivepurchase behavior arises from situational constraints, such as a

lack of viable alternatives, or usage situations, such as habit(Henderson et al. 2011). Regardless of their cause, customerbehaviors can explain financial outcomes as loyalty-basedpurchase activities.

Measurement composition and study-specificcharacteristics in loyalty research

Despite clear delineations between attitudes and purchase be-haviors, theories of customer loyalty suggest both are integral(Dick and Basu 1994; Oliver 1999). Furthermore, some re-searchers characterize loyalty as a general orientation reflectedby non-purchase behaviors, such as advocacy (Jones et al.2008), willingness to pay a premium (Chaudhuri andHolbrook 2001), or continued silence in the hope that thingsget better (Hirschman 1970). As a result, loyalty measures areoften fuzzy; despite its duration, literature on loyalty presentsad hoc measures that are sometimes composed of attitudinalitems, sometimes composed of behavioral items, or both—oreven both together with items that measure ancillary con-structs. For example, many researchers include word of mouth(WOM) items in their operationalization of customer loyalty(Evanschitzky et al. 2012), despite both theoretical (Dick andBasu 1994) and empirical (de Matos and Rossi 2008;Söderlund 2006) arguments for their separation.

In addition, researchers examine customer loyalty in vari-ous research settings, creating research-specific measurementcharacteristics that may exert influences on results. We con-sider two key characteristics: temporal orientation and target.Temporal orientation refers to whether loyalty is measured asa past account or future predictions of loyal attitudes and be-haviors. For example, a customer might be asked to recallprevious instances of being loyal (Ailawadi et al. 2008;Davis-Sramek et al. 2009) or else estimate future intentionsto be loyal (Johnson et al. 2006; Wagner et al. 2009). Thetarget is the attribution customers make about to whom orwhat they are loyal. For example, loyalty may be Bownedby^ or directed toward the selling firm or a salesperson(Palmatier et al. 2007). We consider the effects of both mea-surement composition and study-specific characteristics in thesubsequent sections.

Conceptual model and hypotheses

To understand how loyalty may vary depending on itsoperationalization, we first consider how linkages in the ante-cedents → customer loyalty → outcomes framework varydepending on the use of attitudinal or behavioral loyalty. Byexamining attitudinal and behavioral loyalty as separate me-diators, we can isolate relative differences in both their mainand interaction effects. Therefore, we evaluate how the theoryunderlying each element supports distinct predictions. We

only include constructs in our conceptual framework if priorstudies have demonstrated at least three empirical links be-tween the antecedent and attitudinal and behavioral loyalties,to enable our tests of the differences through meta-analysis.We also include measures that feature both attitudinal andbehavioral loyalties to support moderation analyses. We iden-tified four antecedents (commitment, trust, satisfaction, andloyalty incentives) and two outcomes (WOM and perfor-mance) that meet these criteria. Table 1 summarizes the con-structs included in the model, their definitions, and commonaliases. Furthermore, we evaluate other sources of heteroge-neity identified in our literature review (measurement compo-sition, study-specific characteristics) and probe for additionalsources of heterogeneity by coding study-level factors to testtheir effects on loyalty-to-outcome linkages. Consistent withour research questions, our hypotheses focus on comparativedifferences among the links in our model.

Loyalty antecedents

Commitment, trust, satisfaction, and loyalty incentives (e.g.,reward programs, perks, favorable treatment) have all beenpositively linked to customer loyalty, but we expect them tohave differential effects on attitudinal and behavioral loyalties.Attitudinal loyalty results from positive evaluations of a sellerbased on previous exchange experience (Brakus et al. 2009;Liu-Thompkins and Tam 2013). Drivers of loyalty that pri-marily enhance a customer’s evaluation of the exchangeshould have a stronger effect on attitudinal than on behavioralloyalty. Conversely, behavioral loyalty results from situationaltriggers and habit (Gustafsson et al. 2005; Johnson et al.2006), which may not involve a strong attitudinal component.Thus drivers of loyalty that primarily operate as situationaltriggers in an exchange should have a stronger effect on be-havioral than on attitudinal loyalty. Commitment, or the desireto maintain a valued relationship (Moorman et al. 1992), trust,which is confidence in the reliability and integrity of a seller(Morgan and Hunt 1994), and satisfaction, which is the per-ceived difference between prior expectations and actual per-formance (Tse andWilton 1988), all contribute to a customer’spositive experience. Commitment and trust create the sensethat customers are in a pleasurable relationship rather than apassing transaction (Palmatier et al. 2006); satisfaction pro-vides a comparative basis (prior expectation versus actual ex-perience) on which to develop attitudes (Geyskens andSteenkamp 2000). Therefore, commitment, trust, and satisfac-tion should have stronger effects on attitudinal loyalty than onbehavioral loyalty. Alternatively, loyalty incentives are addi-tional Bextrinsic^ enticements meant to encourage repeat pa-tronage (De Wulf et al. 2001), so they might operate as repur-chase reminders that reduce effortful purchase considerationsand encourage habitual purchasing or as rewards for the pos-itive behavior of repurchasing (Henderson et al. 2011).

we expect loyalty incentives to operate primarily through be-havioral rather than attitudinal loyalty. Finally, as the theory ofplanned behavior predicts and prior research demonstrates, weexpect attitudinal loyalty to affect behavioral loyalty positive-ly (Ajzen and Fishbein 1980; Chaudhuri and Holbrook 2001).

H1: (a) Commitment, (b) trust, and (c) satisfaction havestronger positive effects on attitudinal loyalty than onbehavioral loyalty.

H2: Loyalty incentives have stronger positive effects on be-havioral loyalty than on attitudinal loyalty.

H3: Attitudinal loyalty positively affects behavioral loyalty.

Loyalty outcomes

We anticipate that the evaluation- and action-based mecha-nisms underlying attitudinal and behavioral loyalties differen-tially influence WOM and performance outcomes. Becauseattitudinal loyalty is associated with positive evaluations of aseller, and evaluations are abundant and easy to communicate,the effect of attitudinal loyalty should be strongest for WOM.Behavioral loyalty instead might not include a strong, acces-sible attitudinal component, which provides the basis forWOM (Berger and Schwartz 2011). Therefore, the effect ofbehavioral loyalty on WOM should be weaker than that ofattitudinal loyalty. For performance, we expect an oppositepattern of effects. Attitudinal loyalty tends to be based onconformity (Berger and Heath 2008) and may exist despitesituational constraints (e.g., financial, location) that impedeactual purchases (i.e., loyalty can be aspirational), so we ex-pect its effect on performance to be weaker. Instead, behav-ioral loyalty, which is based on a conation or readiness to actand is tied directly to purchase, should have a stronger effecton performance.

H4: The effect of attitudinal loyalty onWOM is greater thanthe effect of behavioral loyalty.

H5: The effect of behavioral loyalty on performance is great-er than the effect of attitudinal loyalty.

Role of measurement composition and study-basedcharacteristics

Researchers use different compositions of loyalty measures,which should moderate the effect of loyalty on outcomes.Dick and Basu (1994) provide a strong conceptual argumentthat neither a relatively high attitude nor a behavioral inclina-tion to purchase repeatedly are sufficient to capture customerloyalty fully. Customers with high attitudinal loyalty go togreater lengths to support a seller, and their cognitive biaseshelp them resist competitive persuasion attempts through

mechanisms such as avoidance or counterarguments(Ahluwalia 2000; Park et al. 2010). However, these customersalso may lack the ability or opportunity to support the seller(e.g., financial constraints). Behavioral loyalty directly in-creases seller revenues through frequent repurchasing anddemonstrates the customer’s ability and opportunity to sup-port the seller. However, these benefits may be short lived ifcustomers lack the motivation to continue their purchase be-haviors when their environment changes. Behaviorally loyalcustomers with low attitudinal loyalty also may be more likelyto exploit their relative importance and seek to extract extraconcessions from the seller. Thus, customer loyalty shouldcapture both behavioral and attitudinal aspects, to reflect cus-tomers’ desire, opportunity, and ability to support the sellerfinancially while avoiding competitors. Because measuresthat combine attitudes and behaviors capture the varianceaccounted for by each aspect of loyalty, we expect combinedmeasures of loyalty to exert a stronger effect on performanceoutcomes than either attitudinal or behavioral measuresalone.

Yet broad measures of loyalty that include WOM itemsmight attenuate the predictive effect of loyalty on performanceoutcomes, because WOM is a socially complex phenomenonthat involves self-image concerns, consideration for others’interests, and serendipitous accessibility (Berger andSchwartz 2011; De Matos and Rossi 2008; Söderlund 2006).Therefore, even though WOM and loyalty are correlated,measures of loyalty that include WOM items may captureunrelated or even countervailing effects (e.g., customers maybe very loyal to a condom company but unlikely to recom-mend it), so they will be less effective at predicting overallperformance.

H6: Measures of loyalty that include both attitude and be-havioral items have a stronger positive effect on WOMthan separate measures of attitudinal or behavioralloyalty.

H7: Measures of loyalty that include both attitude and be-havioral items have a stronger positive effect on perfor-mance than separate measures of attitudinal or behav-ioral loyalty.

H8: The positive effect of loyalty on performance appearsweaker when loyalty measures include WOM.

We also find systematic variation in the characterization ofcustomer loyalty across extant literature, particularly in termsof the temporal orientation and loyalty target(s). Althoughresearch questions or contexts might restrict researchers’choices of forward-looking versus backward-looking loyaltymeasures, we expect backward-looking loyalty measures toexhibit a stronger effect on both objective performance andpositive WOM. First, backward-looking loyalty assessmentstend to be more accurate, because customers avoid the

Page 6: Building, measuring, and profiting from customer loyaltyvariation in the conceptualization and operationalization of loyalty, which may explain heterogeneity in loyalty-related effects

difficulty of imagining obstacles (e.g., price) that might inter-fere with future purchase behaviors (Ajzen 2002; Zimbardoand Boyd 1999). Second, forward-looking loyalty relies ontop-of-mind factors, whereas backward-looking loyalty bene-fits from subtle psychological mechanisms that offer powerfulpredictors of future behavior (e.g., cognitive dissonance, hab-it, sunk costs, switching costs; Henderson et al. 2011).Therefore, both attitudinal and behavioral loyalty should havegreater influences onWOM and firm performance when mea-sured as backward-looking rather than forward-lookingorientation.

H9: Backward-looking loyalty exhibits a stronger effect on(a) objective performance and (b) word of mouth thandoes forward-looking loyalty.

Although targets of loyalty frequently vary, researchoften ignores the potential implications of this variance.Loyalty to the firm should be a better predictor of objec-tive performance than loyalty to a salesperson, for severalreasons (Palmatier et al. 2007). First, loyalty to a sales-person creates dangers, in that salespeople frequentlychange positions, so the time when firms can benefit fromthis loyalty is relatively short; this loyalty also mighttransfer to a competitor if the salesperson switches firms.Second, salespeople may act opportunistically as agentsof the firm and offer their favorite customers unnecessarydiscounts or perks to gain personal favor (Palmatier et al.2009). Third, the salespeople to whom the customer ismost loyal represent only a limited portion of the firm’stotal offering, such that customers usually must deal withmultiple salespeople, brands, and locations. This narrowrepresentation restricts the benefits that might accrue ifthe same amount of loyalty were directed to the firm asa whole. Thus, we expect firm loyalty to have a greaterimpact on performance than salesperson loyalty does.

However, loyalty to a salesperson may be a better predictorof WOM, because customers can be more confident thatothers following their recommendations will enjoy a similarlypositive experience if they recommend a specific salesperson.Customers view salespeople as more consistent or entatitivetargets than firms, which comprise multiple salespeople,brands, and locations. Thus, when assessing an individual asopposed to a firm, Bcustomers are quicker to form judgments,believe the judgments more strongly, and are more likely toact on the beliefs^ (McConnell et al. 1997, p. 759). Loyalty tosalespeople therefore should have a greater impact on positiveWOM than loyalty to a firm, because it is based on a moreconsistent target.

H10a: The positive effect of customer loyalty on objectiveperformance increases when loyalty targets the firmrather than the individual salesperson.

H10b: The positive effect of customer loyalty on word ofmouth increases when loyalty targets the individualsalesperson rather than the firm.

Empirical study

To determine BWhat is customer loyalty?^ we begin by de-scribing our data collection process. Then, to investigateBHow is loyalty measured?^ and BWhat actually matters?^we code the composition of the measurement items that wefind in individual studies and perform a random effects meta-analysis of reliability adjusted, r-to-Z–transformed correla-tions between the constructs in our conceptual model. Withthese meta-analytic data, we perform a structural path analysis(Model 1), followed by a multivariate moderation analysis, orBmeta-regression^ (Models 2 and 3), to test our hypotheses.

Methodology

Data sample and criteria for inclusion We used several ap-proaches to identify potential studies for inclusion in our anal-yses. In the search process, we referred to the EBSCO data-base and reviewed journals ranked in the highest tier(Polonsky and Whitelaw 2006), namely, Journal ofMarketing, Journal of Marketing Research, MarketingScience, Journal of the Academy of Marketing Science,Journal of Consumer Research, and Journal of Retailing, dur-ing 1980–2013. For each article of each volume of thesejournals we evaluated whether the authors measured any con-struct with Bloyalty^ in its name (e.g., Bconsumer loyalty,^Bcustomer loyalty,^ attitudinal loyalty,^ Bbehavioral loyalty^),with the exception of employee loyalty or similar unrelatedconstructs. We then performed a more targeted search of theseand related journals, dissertations, and working papers usingthe Business Source Premier EBSCO, Social ScienceResearch Network (SSRN), ABI/Informs, and PsychINFOglobal databases. To find studies that investigated issues relat-ed to customer loyalty, we used search terms such as Bloyalty,^ Battitudes,^ Brepurchase,^ and related synonyms (seeTable 1) across all scholarly, peer-edited marketing and man-agement journals and dissertations that were electronicallyavailable. Finally, we inspected the reference lists of the majornarrative and empirical reviews of customer loyalty and relat-ed research to identify any potentially missing studies.

The criteria for inclusion required that survey-based studiesprovide the exact item wording and observational studies pro-vide exact measurement definitions, or else reference to theirorigins. So that we could examine the empirical implicationsof heterogeneity across loyalty research, we included a studyif it reported a Pearson correlation coefficient or other statisti-cal information (e.g., β, univariate F, t-statistics, χ2) that we

could use to calculate a correlation coefficient according to theformulas provided by Hunter and Schmidt (1990) or Petersonand Brown (2005).

Our sample does not include studies that rely on choicemodeling to estimate the extent to which loyalty exists in aparticular context. Such studies often estimate the amount ofbrand/retail patronage loyalty by detecting a brand–house-hold-specific utility (e.g., Guadagni and Little 1983; Horskyet al. 2006). This stream of literature is large and well under-stood, but the estimates of brand loyalty are rarely tied to othertheoretical constructs, which precludes them from enteringour analyses.

Item-level coding We examined the exact item wording ofthe measures or the citation that provided the source of themeasures to categorize the type of loyalty studied by the re-searcher accurately. We extracted, coded, and categorizedeach measurement item (i.e., questions responded to by eachstudy’s participants, objective measures), following apredefined set of rules (Kolbe and Burnett 1991).Definitions that reflect the types and elements of customerloyalty outlined in our prior theoretical review are summa-rized in Table 1. Guided in part by our literature review, wedeconstructed each sentence and coded the language of theitems in each study for common content (e.g., attitudes, be-haviors, WOM, temporal orientation, target). Two coders in-dependently evaluated each article. Fewer than 6% of the ef-fects differed across the double coding procedures, and dis-agreements were resolved through discussion.

With this procedure, we could examine the bundle of itemsthat each researcher chose to measure loyalty and therebydetermine their choice of loyalty conceptualization and theextent to which they maintained content validity. The insightsfrom this content analysis stemmed from our determination ofhow each sample conceptualized loyalty, using (1) only atti-tudinal measures, (2) only behavioral measures, (3) both atti-tudinal and behavioral measures as separate constructs, or (4)attitudinal and behavioral measures in the same scale as asingle construct. The loyalty conceptualization thus reflectsthe researchers’ choice and bundling (e.g., mean average) ofitems. Table 7 in the Web Appendix provides a summary ofthe final database of 163 studies and their corresponding cod-ing decisions.

Meta-analysis To examine the differential effects of attitudi-nal and behavioral loyalty and to maintain construct validity,we used a subsample that included attitude-only and behavior-only measures (i.e., no mixed or Binclusive^ loyalty mea-sures). In addition, we included constructs only if we had atleast three effects between each construct and all otherconstructs in the model in our effort to develop the inputcorrelation matrix (Palmatier et al. 2006). Thus, the structuralpath analyses used to test H1–H5 were based on 126 studies,

151 separate samples, and 713 effects using attitude-only andbehavior-only measures of loyalty.

To this subsample, we applied meta-analytic techniques togenerate a correlation matrix of all constructs to use as inputfor the structural path models (Rubera and Kirca 2012; Zablahet al. 2012). After compiling the data, we adjusted every cor-relation for reliability (attenuation correction) by dividing it bythe product of the square root of the reliabilities of the twoconstructs (Hunter and Schmidt 2004). We transformed thereliability-corrected correlations into Fisher’s z-coefficients,and then performed a random-effects meta-analysis on theFisher z-coefficients. Following standard procedures(Shadish and Haddock 2009), we next transformed the z-scores back to r-correlations to obtain the revised, sample-weighted, reliability-adjusted correlation coefficients and95% confidence intervals with associated t-statistics (Hedgesand Olkin 1985; Zablah et al. 2012). The random-effects ap-proach provides more realistic, less inflated estimates of aver-age effect sizes; accounts for variability in true effect sizesacross studies; and is generalizable to a population of potentialstudies (Raudenbush 2009). We addressed the potential prob-lem of selective publication bias in several ways. First, wecomputed and report the Q statistic (d.f.=n–1) test of homo-geneity (Rosenthal 1979). Second, we tested for publicationbias with funneling and trim-and-fill analyses (Homburg et al.2012), neither of which suggested publication bias was anissue.

Structural path analysis Meta-analytic correlations be-tween all constructs in the model produced by the anal-ysis and formed into a meta-analytic correlation matrixprovided the input for the structural path analyses inMplus 7.11 (Zablah et al. 2012). Our conceptual modelincludes commitment, trust, satisfaction, and loyalty in-centives as antecedents and WOM and performance asoutcomes. Model 1 tests our hypotheses in the presenceof paths from all antecedents to both attitudinal and be-havioral loyalties and with both loyalties linked to bothoutcomes, such that attitudinal loyalty is modeled as anantecedent of behavioral loyalty. All the constructs areobserved variables, antecedents may covary, and we usedthe harmonic mean (n=5671) across all correlations asthe sample size (Rubera and Kirca 2012). Our choiceto use the harmonic mean provides more conservativetesting than the use of the arithmetic mean or medianbecause it give less weight to substantially large cumu-lative samples sizes typical of meta-analyses, and as suchis a common and strongly recommended decision formeta-analytic structural equation models (Pick andEisend 2014). We examined within-model hypothesizeddifferences in path coefficients by setting the correspond-ing paths to be equal and testing for significance usingWald Chi-square tests.

Multivariate moderation analysis To examine the moderat-ing effects of sources of heterogeneity, we expanded the sam-ple that we used for the structural path analysis to includeBinclusive^ measures of loyalty. With this approach, we cancompare the effects of attitudinal-only, behavioral-only, andvarious inclusive forms of customer loyalty elements with ahierarchical linear model (HLM), in which the effects arenested within studies. We performed our analysis byregressing the moderator variables on correlations (meta-regression) to account for within-study error correlation be-tween effect sizes (Homburg et al. 2012; Rubera and Kirca2012), coding for the specific qualities of each construct weexamine. To evaluate how the effect of loyalty on WOM andperformance varies across (1) loyalty aspects (H4–H7), (2)other conceptual features (H8–H10; WOM inclusive, tempo-ral orientation, and target), and (3) study-level factors thatserved to test robustness (e.g., business vs. consumer markets,common method susceptibility), we included studies with anytype of loyalty that reported an effect on either WOM or per-formance. By including all forms of loyalty in this analysis,we established a sample that is sufficiently large to supporttests of all moderation effects simultaneously while also ac-counting for loyalty aspects. Thus, the multivariate HLMmoderation analyses were based on 32 (30) studies, 41 (32)separate samples, and 68 (57) effects for WOM (perfor-mance), using all measures of loyalty.

As a replication and robustness test, we also evaluated thedifferences between loyalty operationalizations by dummycoding an effect as equal to 1 if the loyalty measure was amixture of attitudes and behaviors in a single scale, consistentwith 35% of our sample, and 0 if it included only attitudes orbehaviors. In addition, as an alternative test of H4 and H5, wecaptured the moderating effect of the mixture of attitudinaland behavioral items by coding the ratio of attitudinal to totalitems used in the measure of loyalty (1 = all attitudinal, 0.5 =half attitudinal and half behavioral, 0 = all behavioral). Thesetwo moderators reflect extant research, where (0, 0) indicatesbehavioral loyalty, (0, 1) is attitudinal loyalty, and (1, ratio)serves as a loyalty proxy with varying mixtures of attitudinaland behavioral items, as is common.

We also evaluated other conceptual features by dummycoding whether a loyalty effect was WOM inclusive to testH8 (1 = measure included at least one WOM item, 0 = mea-sure did not include any WOM items). To evaluate the mod-erating effect of temporal orientation, we coded the ratio offorward-looking to total loyalty items for each study effect totest H6 (1 = all forward-looking, 0.5 = half forward- and halfbackward-looking, 0 = all backward-looking). For the moder-ating effect of the target, we dummy coded the measure foreach study effect for the loyalty target to test H10 (1 = indi-vidual salesperson, 0 = ambiguous, −1 = the firm).

Finally, to understand and control for potential influencesof study-based features on our results, we coded and tested the

moderating effects of six study characteristics (Albers et al.2010; Homburg et al. 2012; Sethuraman et al. 2011).Specifically, we used a dummy to code whether a loyaltyeffect was from business or consumer markets (1 = business,0 = ambiguous, −1 = consumer), pertained to brand loyalty (1= Bbrand^ was included in the construct name, context, or anyitems, 0 = not brand-related in any way), appeared in an un-published journal article or dissertation (1 = unpublished ordissertation, 0 = published), and was susceptible to commonmethod bias (1 = used a method or sample susceptible tocommon method bias, 0 = not susceptible to common methodbias). To account for the last two study features, we usedmean-centered continuous coding schemes. We evaluatedany longitudinal effects according to the four-digit year ofthe study’s publication date; for journal quality, we codedthe Journal Eigenfactor Scores for the source of each loyaltyeffect, such that unpublished journal and dissertation effectswere assigned the sample mean value (West and Bergstrom2013).

Results

Item-level content analysis Table 2 shows the breakdown ofthe loyalty constructs in our sample, coded at the item level,which helps address our second research question. Overall, wefind that though many researchers maintain attitudinal loyaltyand behavioral loyalty as separate constructs (65% of studies),a substantial set combine attitudinal and behavioral items to-gether (35% of studies). Furthermore, many researchers ex-amine only behavioral (43% total) or attitudinal (7%) loyalty,but only 15% examine both attitudinal and behavioral loyal-ties in the same study, as separate constructs. Studies withbehavior-only or attitude-only measures of loyalty, typicallylabeled Bloyalty^ without qualifiers, potentially misrepresentthe effects of the antecedents on loyalty and loyalty’s impacton outcomes, because attitudes and behaviors have divergenteffects (Baker et al. 2002; Brexendorf et al. 2010; Burton et al.1998; Maxham and Netemeyer 2002).

Among the 35% of researchers examining customer loyaltyusing both attitudinal and behavioral measures in the sameconstruct, more than half (18% of total sample) operationalizeloyalty with WOM as an indicator of loyalty (Table 2, PanelA). Although WOM and loyalty are related, the prevalence ofWOM as a measure of customer loyalty conflicts with boththeoretical (Dick and Basu 1994) and empirical (De Matosand Rossi 2008; Söderlund 2006) arguments for their separa-tion. In addition, the use of forward- versus backward-lookingloyalty measures is unevenly divided across studies, at 59%and 41%, respectively (Table 2, Panel B). Prior researchshows that the abstract cognitive processes of reconstructingthe past and constructing the future influence decision making(Zimbardo and Boyd 1999), so the selection of a particulartemporal measurement may create variance in empirical

(15%) and to an individual salesperson (13%). However, re-searchers typically fail to qualify or acknowledge the loyaltytarget (Table 2, Panel C), even though firm- and salesperson-

Page 11: Building, measuring, and profiting from customer loyaltyvariation in the conceptualization and operationalization of loyalty, which may explain heterogeneity in loyalty-related effects

based loyalty reflect different decision processes that differen-tially affect performance (Palmatier et al. 2007).

Meta-analysis and structural path analysis (Model1) Table 3 contains the sample-size weighted mean meta-analytic correlations, total Ns, number of effects, coefficientt-values, 95% confidence intervals, and corresponding Q sta-tistics among the antecedents, attitudinal and behavioral loy-alty, and outcomes in our model. We used this information tocalculate our structural path analysis in Mplus 7.11. The mod-ification indices suggested modifications to the initial hypoth-esized model to improve fit, by allowing the conceptuallyrelated constructs of commitment, trust, and satisfaction tocorrelate with outcomes. Importantly, prior research supportsthe inclusion of these links considering the well documentedinfluence of all three constructs on performance and word ofmouth (Morgan and Hunt 1994; Palmatier et al. 2006). Thesechanges resulted in acceptable fit statistics for Model 1: chi-square (χ2 (2)) = 174.75, comparative fit index (CFI) = 0.99,and standardized root mean residual (SRMR) = 0.04. Figure 1shows the results of our final structural path analysis usingmeta-analytic data (Model 1), with standardized beta coeffi-cients and construct R-square values.

Examining our model in relation to our third research ques-tion, we find that trust (βAtt=0.27 vs. βBeh=0.22, χ

2(1) =16.41, p<.01) and satisfaction (βAtt=0.25 vs. βBeh=0.04,χ2(1)=115.06, p<.01) have stronger positive effects on attitu-dinal than on behavioral loyalty, in support of H1b and H1c,respectively. However, commitment is equally powerful forbuilding both attitudinal and behavioral loyalty (βAtt=0.34vs. βBeh=0.35, χ

2(1) = 2.80, p>.05), so we cannot confirmH1a. Furthermore, loyalty incentives (βAtt=−0.08 vs. βBeh=0.01 (n.s.), χ2(1) = 31.16, p<.01) do not have a significantlystronger positive effect on behavioral loyalty than on attitudi-nal loyalty, so we reject H2. Consistent with H3, attitudinal

loyalty has positive, significant impact on behavioral loyalty(βAtt=0.10, χ

2(1) = 174.75). We also find support for H4, inthat the effect of attitudinal loyalty on WOM is stronger thanthe effect of behavioral loyalty on WOM (βAtt=0.41 vs.βBeh=0.19, χ

2(1) = 94.06). On the flipside, the effect of be-havioral loyalty on performance is greater than that of attitu-dinal loyalty (βAtt=0.02 (n.s.) vs. βBeh=0.27, χ

2(1) =133.98), in support of H5.

Multivariatemoderation analysis (Models 2 and 3) Table 4shows the results of our two moderation analyses (WOM inModel 2; performance in Model 3). By using an expandedsample (all measures of loyalty linked to outcomes rather thanjust attitude-only and behavior-only measures) for these twopaths and simultaneously controlling for other potential mod-erators, we retested some hypotheses to increase confidence inour findings related to our third research question, BWhatmatters?^ The positive effects of loyalty on WOM (β=0.33,p<.05) and performance (β=−0.34, p<.05) are significantlymoderated in opposite directions by the ratio of attitudinalitems in the loyalty measure, corroborating our support forH4 and H5. A higher percentage of attitudinal items enhancesthe effect of loyalty on WOMwhile simultaneously suppress-ing its effect on performance. Similarly, the positive effects ofloyalty on bothWOM (β=0.31, p<.05) and performance (β=0.11, p<.05) are significantly moderated by measures that usea mix of attitudinal and behavioral items in the same constructrather than attitude- and behavior-only loyalty measures, infurther support of H7 and H8. A non-significant intercept of0.35 further reflects that the effect of loyalty on WOM isdependent upon its conceptualization.

The positive effect of loyalty on performance decreases(β=−0.44, p<.05) in loyalty measures that contain at leastone WOM item, which implies that WOM-inclusive loyaltymeasures are less predictive of performance, in support of H6.

We also find support for H9a and H9b, focused on the tempo-ral orientation of loyalty, because the effects of loyalty onWOM (β=0.13, p<.05) and performance (β=−0.20, p<.05)are significantly moderated in opposite directions by the ratioof forward-looking items in the loyalty measure. A higherpercentage of forward-looking, relative to backward-looking,loyalty items enhances the effect of loyalty on WOM whilesimultaneously suppressing its effect on performance.However, we did not find support for H10a and H10b, whichproposed that the effect of loyalty on outcomes would bemoderated by the target (individual versus firm) (WOM: β=0.10, p>.10; performance: β=0.03, p>.10).

With respect to other (non-hypothesized) study fea-tures, we find that the effect of loyalty on WOM is slight-ly stronger in business (vs. consumer) markets (β=0.10,p<.05), and the effect of loyalty on WOM has grownstronger over time (β=0.03, p<.05). However, the effectof loyalty on outcomes did not vary significantly forbrand loyalty, unpublished sources, methods susceptibleto common method bias, or journal quality. These find-ings increase our confidence that our sample is represen-tative and unlikely to suffer from potential inclusion ormethod biases that emerge when aggregating a sampleof studies for meta-analytic research (Sethuraman et al.2011).

Post hoc analysis (Model 4)

Researchers often conceptualize customer loyalty as aBfavorable correspondence between attitudes and behaviors,^ stemming from an underlying motivation to maintain a re-lationship with a particular entity (Dick and Basu 1994, p.102;see also Brady et al. 2012; Sirdeshmukh et al. 2002). Ourmoderation analysis (Model 2 and 3) shows that the positive

effects of loyalty on both WOM and performance are signif-icantly and positively moderated by measures that use a mixof attitudinal and behavioral items in the same construct(WOM β=0.31, p<.05; performance β=0.11, p<.05); weinvestigated this finding with a post hoc structural path anal-ysis that parallels Model 1. Specifically, we modeled attitudi-nal and behavioral loyalties as reflective indicators of a latentconstruct (i.e., loyalty), with all antecedents and outcomeslinked to it according to the data we used in our first structuralpath analysis. As with Model 1, we modeled all constructs asobserved variables (except for loyalty as a latent construct),allowed the antecedents to covary, and used the harmonicmean (n=5671) across all correlations as the model’s samplesize (Rubera and Kirca 2012).

Figure 2 contains the results of our post hoc structuralModel 4, which provides slightly improved model fit sta-tistics: χ2(4) = 130.38, p<.05, CFI=0.99, and SRMR=0.01. To gain insight into the nature of customer loyalty,we compared the 95% confidence intervals of the stan-dardized beta coefficients from Model 1 against our posthoc model with loyalty as a latent construct. Mirroring theresults from our moderation analyses, modeling customerloyalty as a single latent construct results in stronger stan-dardized coefficients for performance (βLoyalty=0.51,[0.46, 0.57]) compared with either attitudinal (βAtt=0.02, [−0.01, 0.06]) or behavioral (βBeh=0.27, [0.24,0.30]) loyalty alone. We find a similar pattern of resultsfor the effect of loyalty on WOM (βLoyalty=0.54, [0.47,0.62]; βAtt=0.41, [0.39, 0.43]; βBeh=0.19, [0.17, 0.21]);the model that includes both attitudinal and behavioralelements to capture customer loyalty results in better fitand stronger effects than models that maintain either ele-ment separately. These findings support the concept thatfirms benefit most from Btrue customer loyalty,^

involving a positive cognitive state (attitudinal loyalty)manifested as positive behavioral actions (behavioral loy-alty) (Dick and Basu 1994; Oliver 1999; Sirdeshmukhet al. 2002).1

Strengthening the loyalty framework for researchersand practitioners

From this precise inventory and examination of the primaryconceptualizations of customer loyalty, we derive theoreticaland practical insights to guide marketing research and prac-tice. By synthesizing decades of research, we (1) provide asingle conceptual definition of loyalty, (2) describe how re-searchers should approach empirical definitions to clarify cru-cial aspects of their treatment of loyalty and reduce measure-ment heterogeneity, and (3) provide exemplary loyalty mea-sures, which we summarize in Table 5. We also provide adatabase of recent loyalty-related studies in marketing (WebAppendix, Table 7) and a summary of best practices in termsof study design and methodological choices (Table 6).

From a conceptual standpoint, customer loyalty is a collec-tion of attitudes aligned with a series of purchase behaviorsthat systematically favor one entity over competing entities.However, empirical definitions should append a temporal as-pect (backward-looking vs. forward-looking), because of itsinfluence on how loyalty gets processed psychologically andits ultimate impact on performance outcomes. To address var-ious combinations of empirical definitions, we offer 10 exem-plary items, extracted from various studies that broadly cap-ture elements (attitudes and behaviors) and study-specificcharacteristics (temporal aspect, target) that influence loyalty.We thus offer specific advice to researchers and practitionersto help them capture the customer loyalty construct more ac-curately and reap its benefits.

Guidance for researchers

Every loyalty study should consider four primary conceptualguidelines. First, if researchers seek to understand how ante-cedents create loyalty, loyalty must be measured and reportedas an attitude or behavior separately, because the antecedentsdifferentially build each element. Satisfaction (Model 1) haslittle effect on behavioral loyalty (β=0.04, p<.05) but a strongeffect on attitudinal loyalty (β=0.24, p<.05), for example.Other antecedents that we did not consider in the current studyplausibly should exert similarly distinct effects, and ignoringsuch differences could produce misleading results that dependmore on the loyalty element measured than on the actual effi-cacy of the loyalty-building strategy. Second, if researchersseek to understand the effect of loyalty on objective

performance outcomes (e.g., revenue, profit), they must mea-sure loyalty as both an attitude and a behavior, because thiscomposition offers the strongest effect on objective perfor-mance (β=0.11, p<.05; Table 1, Model 3). Third, if researchaims to investigate WOM outcomes, attitudinal loyalty maybe the best predictor, because behaviors reflect potential con-straints (e.g., size of wallet, store location) that are less impor-tant for WOM outcomes, whereas technology and other socialshifts appear to enhance the effect of loyalty on WOM overtime (β=0.03, p<.05; Table 4, Model 2). Although re-searchers are cognizant of fusing WOM items into their mea-sures of loyalty, they should work to avoid doing so, accord-ing to our empirical evidence this common practice under-mines the linkage between loyalty and performance, as wellas the theoretical reasons for the separation (de Matos andRossi 2008; Dick and Basu 1994; Söderlund 2006). Fourth,researchers studying loyalty will be better served byemploying backward-looking measures, which also helpguard against potential inflation of the link between loyaltyand WOM (β=0.13, p<.05; Table 4, Model 2). In Table 6 wesummarize best practices derived from recent meta-analysespublished in Journal of Marketing, Journal of MarketingResearch, Journal of Consumer Research, and Journal ofthe Academy of Marketing Science for key research decisions(sample, measurement, heterogeneity, and analyses), whichwe used to guide our methodological approach.

Guidance for practitioners

We offer three primary practical recommendations. First,even if assessed with just two questions (e.g., BWhat isyour attitude about X relative to its competitors?^ andBHow often do you purchase from X instead of itscompetitors?^), customer loyalty measures need to reflectboth attitudes and behaviors, because both aspects ofloyalty together have a stronger effect on objectiveperformance than either alone. The loyalties expressedby a firm’s loyal customers often differ in composition:some customers are only attitudinally loyal or only behav-iorally loyal, and others are both simultaneously, and eachgroup exerts significantly different effects on outcomes(Dick and Basu 1994). Thus, the value of loyalty for aseller depends on not only the level of loyalty but also itscomposition in the customer portfolio. A customer withvery high attitudinal loyalty could report a high net pro-moter score (NPS), which is a popular metric amongFortune 500 companies for measur ing loya l ty(Reichheld 2003), but a lack of corresponding behavioralloyalty may reduce the effect of this NPS on objectiveperformance outcomes (Keiningham et al. 2007). Fromthis perspective, the ultimate effect on a specific outcomedepends largely on which loyalty (attitudinal or behavior-al) the firm considers, such that marketing investments1 We thank an anonymous reviewer for their guidance on this point.

Page 18: Building, measuring, and profiting from customer loyaltyvariation in the conceptualization and operationalization of loyalty, which may explain heterogeneity in loyalty-related effects

may be misallocated simply because of the type of loyaltyused to evaluate the investment. Similarly, assessments ofcustomers’ future value may be biased by the loyalty metricused as an intermediate indicator of future performance.

Second, our findings suggest that customer loyaltycannot be bought using incentive strategies but can bebuilt with relational strategies (commitment, trust, andsatisfaction). The $48 billion spent on U.S. loyalty pro-grams likely is not building Btrue^ loyalty (Berry 2013).For an average customer, adding another loyalty card tothe dozens he or she already owns may be less effectivefor building attitudinal and behavioral loyalties (β=−0.08 and 0.01) than building relationships throughcommitment (β=0.34 to 0.35) and trust (β=0.27 to0.22) or improving transaction performance though sat-isfaction (β=0.25 and 0.04) (Model 1).

Third, strategies for capitalizing on WOM should beseparate from strategies aimed at increasing customerloyalty. Including WOM in loyalty measures detractsfrom the construct’s accuracy for predicting performance(β=−0.44, p<.05, Model 3). This point is especiallyimportant in light of our finding that customer loyaltyhas a stronger effect on WOM, but not performance, inbusiness markets than in consumer markets, which like-ly reflects the greater interrelatedness in business rela-tionships. Customers with high attitudinal loyalty likelyspread WOM (β=0.41, p<.05, Model 1) but might notcontribute much to a seller’s bottom line (β=0.02,p>.05) though their behaviors. Therefore, managerswho take a portfolio approach to marketing invest-ments—such that they recognize customer referral valueas separate from customer lifetime value (Petersen et al.2009)—should invest in attitudinal loyalty only insofaras it maximizes their overall customer portfolio lifetimevalue. This implication may be especially relevant forservice settings and business-to-business markets, inwhich the effect of loyalty on WOM is much stronger.

Limitations and directions for research

Typical of meta-analyses, this study has several limita-tions. First, we attempted to include many loyalty con-structs and samples across publication outlets, but wemay have overlooked some. Second, the constructs weinclude and our results are limited to variables forwhich there exist enough data for analysis. Our frame-work is a summary of important loyalty-related con-structs, not an exhaustive list. Our primary objectivewas to ascertain the implications of heterogeneity inextant loyalty conceptualizations and measurements,which required a thorough examination of loyalty’s re-lationship to a few key constructs rather than all con-structs. Third, the heterogeneity in effect sizes that was

not accounted for by our moderation analysis suggeststhat including other, unmeasured moderating factorsmight influence the reported effect sizes.

Further research thus might expand the constructs in-cluded in our customer loyalty framework to examinehow they differentially affect attitudinal loyalty, behav-ioral loyalty, and customer loyalty. Dependence, cooper-ation, communication, conflict, and unfairness all mightexert distinct influences on types of loyalty. Additionally,new research may also consider whether and how vari-ous types of financial outcomes (e.g., Tobin’s Q vs. ROI)are differentially impacted by attitudinal, behavioral, orcombined loyalty. Clarifying these effects would providea richer set of options for managers to tailor their mar-keting actions to enhance WOM and performance, giventheir unique circumstances.

Conclusion

Practitioners recognize the importance of repeat patron-age, but Bfew say they have cracked the code on build-ing long-term loyalty^ (Weissenberg 2013). Despite ele-gant conceptualizations (Dick and Basu 1994; Oliver1999), academics have failed to demonstrate consistentlyhow loyalty builds and when it is most effective. It istherefore no surprise that many of the promises associ-ated with building customer loyalty remain unrealized.We find evidence in support of the premise that thisfailure stems, in part, from a systematic divergence be-tween the conceptualizations (What is customerloyalty?) and measurement (How is it measured?) ofloyalty. We aggregate more than three decades of loyal-ty research to address this divergence and explicatewhen differences between theory and practice influencethe strategy → loyalty → performance process (Whatactually matters?).

Our results offer clear evidence in support of con-struct divergence. Although loyalty is primarily concep-tualized as the alignment of attitudes and behaviors,items used to measure loyalty often include extraneousconstructs (Table 2). In addition, study-specific charac-teristics get incorporated into conceptualizations and/oroperationalizations of loyalty, often with little or no dis-cussion of their potential effects. We have assessed themoderating effect of several aspects of loyalty across163 studies published in marketing journals since 1980that measure loyalty as an attitude, a behavior, or bothto determine when loyalty is most effective forpredicting performance outcomes.
