Okay, so I've found that my iAd supported app has had 100 downloads and has made 284 ad requests. About 177 of those ad requests were fulfilled. Not bad, I'd heard iAd's fill rate was about that, but I dug into the number a little more and was surprised about the reason: iAds simply aren't displayed in many countries. Looking at the "By Country" break down, the UK, Spain, and Italy all have 100% fill rates, the US has a 98.5% fill rate, and France has a 90% fill rate. And then every other country has a 0% fill rate. So, of my 107 ad requests that went unfulfilled, 103 of them came from countries that don't have iAds. These countries that are requesting, but not getting ads are: Turkey - 20 Requests Australia - 17 Canada - 16 United Arab Kingdom - 11 Unknown - 8 China - 7 Sweden - 6 Germany - 4 India, Philippines, Venezuela - 3 each Netherlands, Singapore - 2 each Pakistan - 1 So, any suggestions for how I could start getting ad revenue from these countries? Namely, if an ad network could display ads for Turkey, Australia, and Canada, that'd satisfy half of the requests that are currently not getting fulfilled. Does anyone have suggestions on how to handle this? I'm thinking I could create two different versions of my app, one only available in countries where iAds work, that would be free and iAd supported, and another version of my app only available in the countries where it doesn't, and they'd get it for $0.99. Thoughts?
