the loading order of the ads is *very* important. I got three ads:
2.) 4th paragraph in content
3.) manual 2nd ad in content
Now the display order in my html source code suggests the following order:
1.) 4th paragraph in content
2.) (if exists) manual 2nd add in content
But then Adsense tells me, the most expensive (CPC) ad is the sidebar ad. Which is confusing, because Google says the first displayed ad according to the source code is the best paid one.
On the other hand, the sidebar is 250x250, and the other in-content-ads are small banners.
Is it an issue with the loading order, or the ad size, or both? I'm happy about any feedback!
