UPDATE: And yes, Madvertise was great for me in the past. I’ve made around about 3000€ with them in total, they paid on time & everything. Just in recent months I’ve been unable to get the same results.
I just removed madvertise. My numbers were:
Requests: 77.426
Impressions: 2.074
Fillrate: 2,68% (sic!)
Clicks: 0 (?)
CTR: 0%
Revenue: 0.24 euro.
It was used in a not popular game as a backfill to admob.
I tried madvertize cause of the big money you should gain from it…
But then I tried it for a few days and it always just said “no ads available”.
So I kicked it directly.
