I wrote a free iAd supported app and it was approved by Apple on Friday evening, and I am surprised how low the fill rate is so far. I've had over 1000 downloads, most of which are in the USA. Ignoring other countries and looking at the stats for the USA only over nearly 4 full days, I see: Requests: 1,136 Impressions: 45 Fill Rate: 3.96% Is it normal to have a fill rate that low? I understand that my worldwide fill rate will always be low because some countries will never generate any impressions since they don't run iAds in those countries, but this is for the USA only. Also, I can't find a comprehensive list of iAd prices on Apple's site and developer documentation. As I understand it, different types of ads will generate different amounts of revenue. An add for a $0.99 app won't generate as much per click as an ad from Nisan or the movie Tron for example. Can anybody tell me where to find the rates that I can expect to be paid for each type of ad? I'd appreciate it if anybody in the US could confirm whether the ads show for them or not.
