CPE model allows to quickly scale the campaign: by the second month we returned 2.5 times more users to the Mamsy application than during the first month; by the third month - x4 times more. And by the current day, we are trying to increase our turnover. CTR banners in our DSP is an average of 3-6%.
Based on the three months campaign results, we performed client's KPI — ROAS> 300%, CPO <150 rub. At the same time, we manage to increase volumes due to the fact that CPO of the previously paying users is lower, so we are able to convert the new ones and stay within the KPI framework. CPE model focuses on user engagement rather than clicks or impressions. So basically, client only pay when users engage with their ad.
