AdSense EPC Going Into Freefall!

I am beginning to wonder whether this has anything to do with the MFA/ARB clampdown?

Since June 8th my EPC has dropped 14.39%, my eCPM by 12.21% and comparing Monday 4th v Monday 11th my earnings were down 24.63% with the same number of clicks.

This is a bit too co-incidental for my way of thinking.

No my trade is not on holiday this is a 12 month of the year business generally with few fluctuations.

Yes there seem to be plenty of quality advertisers however I am now seeing a lot of "directory type" sites in AdLinks and they were never there before and checking through the SERPs advertising they are cropping up in the first few pages.

Certainly something significant is happening so far as my sites are concerned and if I have a few more days of this then I shall remove my AdLinks to see if that stops the rot.

Is anyone else seeing similar.

"Bizarro World"... I use that phrase quite a bit. In any event, I'm sure it's me... usually is!

I've gone into a freefall today. Epc down by 80% across a variety of sites and topics. I suppose it could be Smartpricing?

My earnings have rocketed up since June 11-12 (Monday-Tuesday), almost 2x the EPC as usual today! I don't know why and I expect it to stop any time, but it's happening on my both my (semi-related) websites and I'll take it as long as I can get it! Strange that others are seeing a big decline at the same time.

Wednesday was still considerably below average earnings however today the EPC so far has returned to normal levels.

Which dial did they twist this time?

I've heard many people report that Thurs seems to be algo-change-day or Smart-pricing-takes-effect-day whichever you believe in. Personally ours usually seems to switch on Saturdays.

We've been getting the duplicate ads for almost a year, and we told G then, (especially since it used to be somewhere in the TOS that you sould not display identical ads on the same page, and THEY were causing it) but to no avail. It seemed to start when we started using google-ad-region. I'm guessing you're using it too. We just started removing the extra ad blocks since they were obviously redundant and seldom got any additional clicks.

I had one interesting observation the last couple days. Our earnings have been down since Feb right around the time we started noticing something new. Seemed that ads on all pages account-wide or at least site-wide were leaning towards two particular sub-topics. These two topics were those, which in our channel level reports had the overall highest CPM compared to other pages, but are in a relatively narrow topic which does not necessarily appeal to most of the rest of our site. However while the ads did very well CPM-wise, by virtue of either high CTR or high PPC, ON the pages where they were APPROPRIATE, they did NOT do so well on the rest of the site. Since they were not applicable to the other pages, they tended not to get clicked. More of them were of the lower PPC variety, so even when they were clicked, they tended to lower the overal CPM of the pages they were now on inappropriately.
For example, say the site was about all different power tools (our actual case couldn't be further from that topic), with a single page on various jackhammer bits, and another single page on electric screwdrivers. Ads for electric screwdrivers get a nice 35% CTR on their page and jackhammer bits get a lower CTR but since they have a much higher PPC still get a very nice CPM for on their page. The electric screwdriver page, in this example, is our most popular entry point and a #1 for it's keyword phrase on G, but has a relatively low PPC of only .10. But, becasue of the high CTR we wind up with a hefty $35.00 CPM there. The jackhammer bits page is relatively low traffic, but has a decent CTR and a very nice $1.50 PPC, so it winds up with probably a CPM of $85.00. Yet when those same ads start bombarding the radial saw pages, the electric drill pages and even the precision lathe pages, they get relatively no interest and the CPM on those pages has dropped below $2.00 due to the much lower average CTR. Our overall CPM, PPC and Overall earnings dropped to about 1/2.

Then just the other day I decided to try removing the ads just from those two offending pages, totally. It only took about 12 hours and suddenly all the ads went back to the way they used to be a year ago in happier times and our CPM and PPC skyrocketed almost back to the previous levels! I've replaced the ads now (they were rather lucrative in themselves) to see what happens.

I'm begining to think there has been a new flawed algorithm added with good intentions, but bad results, that is doing this and is causing a lot of advertisers earnings to fall. Perhaps it works very well for some types of sites (perhaps ones where the entire site is very focused and ads are interchangable across all topics), but not for slightly more diverse sites like ours, where visitors viewing one part of the site are not interested in ads from another part!

I'm wondering now if it was a total lack of quality ad inventory since yesterday returned to almost normal levels with earnings being 90% of an average Thursday however Page Impression compared to my logs were a good 15% less than I would have expected.

This, however, does not explain the PI metrics appearing normal the rest of the week!

Could there have been so many advertisers not keeping their accounts up-to-date all at the same time?
