Admob revenue on my main game dropped over 60%

[andymc]

Around October 21st I noticed my revenue from my main Android games has dropped by 60%
Has anyone else using admob for revenue noticed anything?
I can't think of anything I've done to cause it, I haven't even updated the games since August!

Impressions are the same? How much is your eCPM? Has it also dropped?

the question is how many people get ads and from where they are. From my experience it is very hard to make a stabile income from games in the mobile world.

Mine is slightly increasing over the last months.

A drop can be anything.

Less frequent players?
