What is Journal Impact Factor?
• Journal Impact Factor is a simple statistics intended to reflect the “impact” of a journal. Basically it indicates the average number of times an article published in the particular journal during the past two years was being cited.
• Journal Impact Factor is based on the Journal Citation Reports which is updated on annual basis.

Journal Citation Reports
• "Journal Citation Reports® offers a systematic, objective means to critically evaluate the world's leading journals, with quantifiable, statistical information based on citation data. By compiling articles' cited references, JCR Web helps to measure research influence and impact at the journal and category levels, and shows the relationship between citing and cited journals. Available in “Science” and “Social Sciences” editions. "
• JCR is part of based on citation data from the Science Citation Index Expanded and the Social Sciences Citation Index. In the past, SCI, SSCI and JCR were the only tools providing verifiable measurement tools of journal impact based on citation statistics. Therefore they have been and still are the most widely recognized journal ranking / measuring tools.

Below is only a simplified explanation of the metrics. For definitions and details, click the help in the JCR journal report
pages
Total Cites Total number of citations for this journal in the JCR year
Impact Factor On average, how many times an article in this journal is being cited – based on articles published in the two previous years
5-Year Impact Factor
On average, how many times an article in this journal is being cited – based on articles published in the five previous years
Immediacy Index On average, how many times an article in this journal is being cited in the same year – based on last year's data (reflects more about the nature of the subject than journal quality)
Cited Half-Life Indicates how far back the older articles in this journal are still being cited (reflects more about the nature of the subject than journal quality)
11
Citing Half-Life Indicates how recent or how old the bibliography referred by articles in this journal are (reflects more about the nature of the subject than journal quality)
Eigenfactor Score The Eigenfactor Score is some kinds of enhanced 5-year impact factor – by giving higher score for getting cited in more influential journals and eliminates self-citation
Article Influence Score
The Article Influence Score is derived from the Eigenfactor Score based on matching the share of the journal's influence against the share of the journal's share of articles. The neutral influence score is 1.00 – thus a journal with article influence score greater than 1.00 indicates that each article in the journal has above-average influence and vice versa

Impact Factor CalculationImpact Factor Calculation

Impact Factor =No. of Cites to 2011 or 2012 items in 2013
No. of items published in 2011 or 2012
Working Example: Impact Factor of Early Childhood Research Quarterly (JCR SSC 2013) = 2.058

To discover how the works of an author are being cited • How many citations received?• Cited by whom?
It can also cover the variant citation data in your search
Finding Citation Counts and Create Alerts for Works Not Indexed in Web of Science
• Important Note: Citation data by Web of Science are only limited to citations recorded in the Web of Science indexed publications.
• Author Finder only finds the citation data for a particular researcher’s publications that are indexed by Web of Science.
• If your article is not indexed in Web of Science or may be it is a book, you can still check how many times it has been cited by Web of Science journals and create an email alert using the "cited reference search" function.
58
Cited Reference Search
• E.g. I want to know how many times the following book has been cited:
Bond, M. H. (1991). Beyond the Chinese face: Insights from psychology. Hong Kong: Oxford University Press.
