how admob/adsense works in android app?

I am trying to understandard how adsense for mobile apps work. The website typically has alot of text to tell the topic of webpage to get relevant ads. But mobile apps (e.g. a game, or some utility app - clock, etc) typically do not have alot of content to get relavant ads.

Can you share your experience on how mobile apps can provide better context for开发者_如何学C ads? Should one have more text in the app?

Thank much.

Admob lets you choose what ad categories you want to display in your apps, as well as specifying the age range. Having all ad categories enabled would increase your chance of an ad being available on the server. If you feel the need to only have ads of a specific category, you can do this. I have not, as my goal is to have a high probability of ad impressions.

Ad Mob also lets you enable Google Ad Sense. You can read about it here.
