Currently I'm using StartApp for showing ads in my app. The eCPM was around $1.40 when it was live on play store but as soon as I removed it from play store, it went to $0.15. I contacted support, they told "Low eCPM is because of removaal of the app from play-store". I don't want to re-upload the app on play store due to some reasons. But I can't stop it completely as the app have more than 23K daily active users and the cost to maintain the app is almost (23 * revenue) generated from ads.
My question is if I use AdMob in my app, will eCPM be affected if the app is removed from play store? OR it doesn't matter if app is live or not in case of AdMob? OR is there any chance of Account Termination if not published to play store?
