AdMob Ads not displaying

Question

I'm adding AdMob ads (say that five times fast) to my finished, published Android app. I added the code from the PDF included with AdMob, following their instructions to a tee. The test ads show up fine on my emulators and specified test devices. They just don't appear in the published marketplace app when you download and run it. I still get impressions on my AdMob page however. Any ideas?

Answer 1

Admob sometimes doesn't have ads to display. This is worse for some apps than others. There are a few things to do to help mitigate this problem:

1. Enable adsense ads - this gives a larger pool of ads
2. Ensure that you have house ads available for all of your apps in Admob. That way, if they can't find paying ads, they'll at least show your house ads. This will significantly raise your fill rate, but not directly raise your income (depends on what you do with the house ads).
