I have been searching around for a little while looking for a complete guide on how to integrate iAds with AdMobs if iAds fails,
The only reason I ask this is that I have iAds and I am noticing a very low fill rate with iAds and would love to have AdMobs fill the spaces. I have read the related post below and feel this is a little outdated (from 2010)
are there any better solutions complete tutorial out there with detailed code that you know about.
