As most of you know, adsense started to feed ads from 3rd party (doubleclick & co doh!) I have a sitewide wide skyscaper and a 728x90 leaderboard in some inner pages. Leaderboard is not shown to subscribed users. Leaderboard impressions are usually 40% less than the skyscraper. Today I'm having less impressions on the skyscraper than the leaderboard. While the leaderboard is on average CTR, the skyscraper has no clicks, and not even a penny as CPM. So far, I saw at least 3 flash ads from 3rd party. (and no, they are not related to my content :-( ) I wonder if impressions from 3rd party are realtime or not. Anyone is experiencing the same?
