I released an app with an iAd in it on Friday. So far it has generated zero impressions with many requests - a fill rate of zero. Most of my requests are in the USA (~90%) so the problem is not that the requests are from countries which iAd does not support).
An older app of mine which is less popular is consistently generating a 98% fill rate despite a lower number of requests.
I was just wondering if it's normal for iAd apps to not generate impressions right away. Should I expect to eventually get impressions after some time, or is something wrong?
It takes 1-4 days for an app to start receiving ads. It's normal1 for the fill rate to be zero or nearly zero for a few days after release.
1: This is not documented on Apple's website anywhere, but Apple iAd representatives confirmed this via email.
Yes it is normal and documented.Have you read - https://developer.apple.com/library/ios/documentation/UserExperience/Conceptual/iAd_Guide/Introduction/Introduction.html
