This looks good. But looks are somewhat misleading. In reality it is a mixed picture.
Because customer acquisition in Q2 2010 was during a period where competition was almost non-existent, the costs of acquisition were lower.
First, based upon our analysis, the latest cohort costs at least 25% more than back in Q2 2010. Hence, on a go-forward basis, each cohort within the same time scale will provide, at best, a 91% ROI with a fast degrading percentage over time.
We say ‘at best’ because, these new customers are worth less and less going forward as
- gross margins is degrading across the industry. Groupon’s average margin is down from 42% in Q1 2011 to 37% Q3 and
- each new customer is lower in quality as the early adopters are also the heaviest users of this channel which will result in
- lower continued spend per customer
