I've been working with this network as an advertiser for a long time.

I've tested different verticals, geos, and formats. A lot of things convert well, but you have to be careful with optimization - that's where the key to success is. There are a lot of sites, as well as a lot of traffic, so if you cut off everything unnecessary in time, you get quite profitable.

I have recently begun to test other CPA-paying campaigns, which also work in an interesting way. The system stops paying for CPA and optimizes your profit making bids. It is very handy.)
