Unlike with niche campaigns(where i get nice success), i find it tricky to get good ctr's on broad stuff.
So here is the campaign i'll try running:
-<50 login count
-feq. cap= 3 per visit
It's a 110x80, my bid will be around 0.36$ and i'll test 5 ads at a time in the campaign. Of course i'll have an angle for my ads.
I'll update a bit later when i'll have some data!
