Adsense seems to be some kind of Sisyphus scheme. Now finally traffic is up and things went back to the 100 $ a day mark and now oh wonder the ecpm tanks by half since beginning of the month again.

First thought it's site targeting, but the advanced report doesn't show this .. hmm.. smartpriced. The website stats are roughly the same procentually of what is incoming.

Very annoying .. It seems that there is a limit that you can not cross.

Me, Economics or Google fiddling that is the question.

On the day the misery started the Website targeted ads fell very low . In the previous month there was only one ocassion that happened. Since then although people wanted to be on my site their CTR is falling and my ecpm although there is no direct match in numbers.

I wonder if there is a link between "smart"pricing and the success of website targeted ads.

Hey MattG3;

We have also recently seen a 50% drop in eCPM, but CTR has also dropped by 30%, so to me, that somewhat rules out smartpricing (showing the same ads after smartpricing would not affect CTR - would it?).

It's almost like the decent, high CTR ads have been pulled. Maybe these advertisers were hit by the recent 'landing page quality' penalty and decided to pull their campaigns? I say this because we had a sharp spike in eCPM for a few days right after the last landing page quality score update... then BAM! - 50% less eCPM and 30% less CTR - across the board, for the last week - in very diverse site contexts and industries.

It's like the overall 'ad quality' has gone down.

Maybe the guy who wrote "The Death of AdSense" is right? (for publishers anyway). CPA ads are getting more and more attractive every day.... at least there's no click fraud chargebacks, or overhanging fear of being dropped - check out this post: [webmasterworld.com...] - a $200K chargeback!

After a great october, same here revenue down a third since the 16th of november, lower than it has been for a year. Right in the busiest time of the year for us as well.

No worries, removed adsense from 50 percent of the pages and swapped it for a relevant affiliate program instead. Overall revenue back up.
