However yesterday marked the worst drop in eCPM and earnings I have ever seen. eCPM is less than 40% of what it was a week ago. This is no minor fluctuation - I produce enough traffic to make this a very significant change.
My traffic has been the same -- and CTR also the same. I am also well aware of seasonal fluctuations in the niche I publish in.
After using the AdSense preview tool - I was astonished to discover that all but one ad (in the extended ad list) appeared to be from the same advertiser. Page names were the same -- but the domain of each ad was different. In fact the domains were all short and nonsensical.
On checking the destination sites - they were all MFA's: A page with a copied article, and multiple AdSense blocks. The ads displayed on the MFA were mostly 'legit' ads. Genuine advertisers selling genuine products.
In order for the MFA publisher to exist they must be making a profit on their 'enterprise'. In simple ROI terms - they must be paying less for ads that what they are making in revenue.
So - tell me - how on earth can the Google AdSense algorithm mess up so badly - by filling entire adblocks with the same cheap paying ads (on a legitimate site) -- while publishing the higher paying (genuine) ads on an MFA.
It is - quite simply - beyond belief. I can only conclude that it is a mistake and the algorithm has some serious defects.
Does anyone have any answers? Forgive me if this situation has been discussed before. We are all familiar with MFA's -- but never have I seen what appears to be the same advertiser occupy every slot in an entire set of publisher sites. My metrics would indicate that this MFA advertiser/publisher must be paying at least 40% of what competitors are paying -- and yet they get all their ads displayed before their competitors. The fact that they use multiple domains seems to somehow manipulate the ad serving algorithm in some way.
Someone has obviously learned how to "beat the system" and it appears to me that adsense is slightly broken.
i had an ads block that show 3 ads.
1st ad domain is infos?123.com
2nd ad domain is infos?101.com
3rd ad domain is infos?201.com
upon checking their domain I found that they have 60 over domain names registered under same host IP address.
I just reported one of those host to AS support.

What I don't understand and feel strange is I can't find a single MFA advertiser on their page. What I see is all guinee advertisers. While my page keep on displaying all the MFA ads.
Is there a way for them to cheat adsense system to always attract high paying ads?
Sure report it to AdSense support -- but how does this stuff get displayed in the first place? What's to stop the same people doing the same thing again?
You can put sites in the filter - but there's a certain amount of trust that for the most part -- Google will publish genuine ads on your site. But for duplicate MFAs to fill 100% of inventory? That's crazy.
yc168: That's exactly my point. How does the MFA manipulate it such that their sites have genuine ads -- but other sites run MFA cheap ads?
They block themselves in the competitive filter ;)
Anyway, sounds like another case of "please, Google, let us block advertisers, not just domain names".
They can block themselves but they cannot block all the rest of MFAs.
there are few hundreds more MFA beside them. no way for them to block all since the filter list only allow 200.
I suspect they have a way to attract high paying publisher. I check their html source code and can't see the adsense scripts. I believe they purposely hide it so that people don't see what they customized the google scripts.
What do you guys think?
It's a weakness in the ad server.
