Although the onset should not have been this drastic do you think that “adsense blindness” may be setting in?
I had a look at my site and it’s not like its showing more than the expected number of PSAs. I have not changed my site/ad layout nor have I changed my ad colour.
Is anyone else seeing this drop in click through rate?
Nothing out of the ordinary in my case. I have been using skyscrapers since the beginning also and not done any major work on my site besides changing my previous ad network skyscraper for Google's and moving in to the top of the right hand navigation menu.
BTW, moving the skyscraper so that it would be displayed in the first screen of my site improved CTR considerably.
My guess on some of what i think we may be seeing is google experimenting with diff algos to maximize benefit for advertisers, publishers, and google..
same thing here wanted to c if any1 else posted this first though. my CTR dropped to 1/3rd pof its regular levels and since i havent made any changes i am 100% sure this has something to do with googles algo. my impressions as well as CPC have remained constant on an average. however such a drastic CTR reduction has never happened. hope google solves it ASAP.
If it is the visitors who come once looking for something and wont come back again I think those CTR should stay the same of course you must figure in if yer traffic has dropped along with it or not.
Is this a real supply/demand issue, or does Google want to keep the click price high? Perhaps they purposely limit the number of ads shown via adsense so they can keep their search engine-based adwords at a high dollar amount?
I think this is why when AdSense began, we got just the two sizes (sky scraper and banner) with the default color and let us run with that for a while. Then we got the new color schemes and DIY color designs. Then we got the two new ad sizes. And I suspect we are about to get some new changes.
And why do they do this? To keep publishers happy by offering little new tidbits here and there so we continue to use AdSense. And more importantly, to combat the entire AdSense blindness issue, to keep visitors clicking on the ads, and keep earning Google money.
On the side note, this thread talks about the recent PSA issue:
