When we check your AdMob income statements, we always find that the fill rate is never reach 100%. Even after we set our AdMob ads to use keyword targeted ads and Google certified ad networks to improve fill rate, the ads are still filled at a rate between 92% to 97%. For example, I have three apps which are using AdMob ads, the fill rate in the past three month are 92.72%, 96.70% and 98.46%.
To maximize the ads fill rate, AdMob introduces AdMob Ad network mediation, which works with Adfonic, AdMob, BrightRoll, Hunt Mobile Ads, iAd, InMobi, Jumptap, Millennial Media and MobFox.

Not only the banner size, it also mediates interstitial formats and tablet size formats on all Android device, iPhone and iPad.
