Hello everyone. I just want to share a statistics how you can reach conversion cost less than 1$ via POPS traffic channel. It's a statistic one of our advertiser for financial offer with Africa geo. What we do: 1. Optimization rules: we add to blacklist sources with 1000 impressions and 0 conversions; 2. We filter sources wit expensive conversions; 3. We create additional campaigns with white lists sources with conversions. How you see on the screenshots, we decrease conversion cost in 3.1 times and increased ad campaign efficient in 3.51 times.
