Your clicks are down? Mine are at ZERO for two days. That is just not normal. I know the economy is bad but my gosh. The clicks cost the viewer nothing. I don't see where that can account for much so where are the clicks? I'd take any!
I'm not involved with adsense, but with the return of very high organic search placements for our site, our visits are still "WAY" down. Think 1998 traffic stats. I think pepple don't want to tempt themselves. I can only think this would affect adsesense click though as well.
On my site the targeting was unusual on 27th to 29th March (very specialised advertisers likely to be of interest to a tiny minority of my viewers). Clicks and earnings reflected this. Seemed to get back to normal yesterday.
Maybe a change to the targeting algorithm that takes a bit of learning time to settle down? Or possibly a glitch.
on one of my sites ctr and ecpm are 90% down. Very strange. I did change menu, layout and urls ten days ago. This could be the reason. Nevertheless i would not expect income going down 90% just by changing the structure of the site. Adsense placement is roughly the same.
ANother site around the same subject has no problem at all?
