There's an app eFasteFree/bFastbFree which pays users for watching ads. User can watch ad by clicking on "Go" button. So I build the same model with different design, but I've got ad serving limit(invalid traffic) 2 times on 2 different accounts. I want to know what am I doing wrong?
P.S: My app is published and approved. I didn't use ad limit on first account but after getting Ad serving limit on 1 account, I added 30 ads limit. Those apps allow user to watch 45 ads per 30 mins. I allow users to watch 30 ads in 30 mins. I'm using mediation too. Also, I've setup my phone as test device and there are no self-clicks. Does using the app on same Wi-Fi on where admob is logged in might be the reason?
