1. Better to track CPA than CPV, as conversion rate from visitor to customer often varies dramatically by channel.
2. Don’t include brand SEM in your SEM CPA.
3. The only truly free channel is people directly typing in your URL. Other ‘free’ channels (SEO, CRM) have some variable cost.
4. Differentiating between acquisition costs of new vs. returning visitors requires investing time and money into your web analytics system.
5. Customers which take time and multiple steps to convert are tricky. Need to monitor both ‘Cost per Sign Up’ conversion.
6. Discounts need to be included in CAC and assigned to correct channel.
Best practice
![Page 14: Understanding customer acquisition costs - a VC's view](https://reader033.vdocuments.mx/reader033/viewer/2022042723/587020d51a28ab7f428b7e67/html5/thumbnails/14.jpg)
Audit:
• What is my CPA by channel, what can I decrease this to?
• What can I increase my customer value to?
• Would each of my acquisition channels make sense at this CPA and value? If not, turn off the ones that don’t. high.
From analysis to action
Growth:
• How do I grow ‘free’ channels? (top tip: start with CRM). What is a realistic target for this?
• How far can I scale up paid channels before they increase to uneconomic levels?
• What other marketing channels should I look at? (10-20% of budget on tests)
• What growth hacks are not too hackneyed?
• Start layering in paid acquisition, starting with the cheapest channels, until you hit your maximum budget or CPA creeps up too high.
![Page 15: Understanding customer acquisition costs - a VC's view](https://reader033.vdocuments.mx/reader033/viewer/2022042723/587020d51a28ab7f428b7e67/html5/thumbnails/15.jpg)
This is still a simplification
Caveats
Ignores halo effects, attribution, difference in values of customers, return rates, increase in acquisition costs as
channels get tapped out, decrease in acquisition costs as conversion rate improves, seasonality etc etc etc
If your marketing budget goes above £10M, worth hiring an econometrician to figure these out
But it is probably the right level of detail for a startup at Series A stage

“The dangerous seduction of lifetime value”
http://abovethecrowd.com/2012/09/04/the-dangerous-seduction-of-the-lifetime-value-ltv-formula/
Challenges / watch outs:
• Lifetime values beyond year 1 are speculative at best
• You don’t know what your churn rate will be. Low sample sizes fom early cohorts, not representative
• Need to include all variable costs
• The values ‘tug at one another’: e.g. increasing price increases churn
![Page 18: Understanding customer acquisition costs - a VC's view](https://reader033.vdocuments.mx/reader033/viewer/2022042723/587020d51a28ab7f428b7e67/html5/thumbnails/18.jpg)
Attribution
• If a user touches multiple marketing channels before becoming a customer, which one do you attribute the sale to?
• Best approach starting out is last-click attribution. Watch outs:• Overstates impact of affiliates and retargeting, by ~30-40%• Understates impact of SEM and SEO by 10-20%• Understates ATL advertising and PR
• Google Analytics is a good enough tool to start with
• As business gets more sophisticated can go for weighted first click / last click, or weight equally through purchase cycle
• At scale worth building full attribution model. Need to do in-house, avoid black boxes and agencies
![Page 19: Understanding customer acquisition costs - a VC's view](https://reader033.vdocuments.mx/reader033/viewer/2022042723/587020d51a28ab7f428b7e67/html5/thumbnails/19.jpg)
Direct traffic
• Direct site visits (brand searches / app store downloads) are often a big % of conversions
• They don’t happen by magic, but how do you attribute?
1. Make sure your analytics is set up properly and you are tracking everything you can (e.g. clicks from emails)
2. Track referrals (e.g. with MentionMe)
3. Strip out all attributable traffic
4. Strip out repeat customers
5. Look for spikes in sales, link back to PR (or app store featuring, promotions or brand advertising)
6. Assume a ‘halo effect’ of paid advertising, 10-20% more conversions
7. Remainder is genuine word of mouth. If it is increasing congratulations – you are viral!

Conversion optimisation
• The most important thing you can do to reduce CPA
• Always be testing
• Without action conversion tends to slightly decrease over time
• Be careful with A-B tests:
• Results may not be significant
• Positive results are not cumulative
• Need to go back and retest as business evolves
• Doesn’t take into account long term effects (e.g. ad blocking)

Two approaches to measure impact of TV advertising
• Measure immediate impact of each TV ad slot
• Adjust upwards for:
• Delayed site visits
• Delayed conversions
• Improvement in click through and conversion rates due to brand familiarity
Bottom up Top down
• Compare overall customer and visitor numbers to organic baseline
• Strip out trackable marketing channels, and adjust for seasonality

Watch outs on TV advertising
• “Media for equity” TV is not free. Account for it at what it would cost in the market (~20% of list price)
• Creative counts. Test it. Don’t be afraid to make it brash: say your brand multiple times
• Track independently from your agency e.g. with TVsquared
• You can test TV with €100K, but the answer will always be ‘it doesn’t work’. Proper test more like €500K
• TV advertising doesn’t work for every company
