AdMob location based advertising

Hi there,

Does anyone of you have experience with tweaking the AdMob requests, e.g. setting keywords, user gender, interests or location?
I am more interested in the keywords and user location, because I have an app for a specific city. So Ads for that specific city would theoretically make more sense.

So, I am interested if anyone of you has similar apps and if AdMob monetization improves after targeting specific keywords or location.


Language controls location.

It does not help in Google.
users search shows app results based on your app download and ranking.
