April 27th, New fruad Detection Scheme used.

Up until April 27th my javascript tracking system consistantly reported 6% more clicks then where shown in the adsense reports. On the 27th adsense started reporting 98% of the clicks i did... The reason it was reporting 6% more before was i don't have the tracking installed on all pages. My site does thouands of clicks a day, so i'm using a big sample... Anyone else noticing changes...

IMO this is somehow related to the observation so many people of us have made that CTR has dropped but EPC has jumped since the 27th. A decline in the way clicks are counted in the AdSense reports would have this effect.

You know what... this is the sort of thing that Google needs to keep us updated on. At least they can write up a weekly report in the AdSense account informing us what's going on... Or even better, they can have guage that shows our account status whether it is in good standing or ready to be booted.

markus007, sorry, I have tried reading it several times but I am unable to understand your message. If your js was reporting more clicks despite not being on all the pages and Adsense is now showing 98% of what your js was showing on less than the full number of pages and.... I'm lost.

Somewhere in there is probably a message that Adsense has now changed the way they count clicks. But I don't understand your numbers/reasoning ;)

I think he means to say that Adsense used to report 6% more clicks than his tracking used to report, but he thought that it was because the script was not in all the pages. However, as of the 27th the situation has been reversed and Adsense now reports a lower number of clicks than his independent tracking.

I would also like to point out that admitting: "My site does thouands of clicks a day" means that the beer is on him.

loanuniverse, thanks for trying to unravel it.

Actually, he seemed to say the exact opposite i.e. "my js tracking consistently reported 6% more clicks than were shown in the adsense report".

But maybe it's me. It's Friday evening. Maybe I need some of that beer you mentioned.

[markus007]

Lets say total clicks for the day that where logged via my javascript are X, before april 27th my adsense reports reported X+(x*6%) after april 27th it reports X-(X*2%). Basically that is a LOT of clicks and $ that have gone missing.

Geez Markus, yesterday you said your EPC had jumped a stunning 250% since the 27th. Since the change in the way clicks are measured started about the same time and is probably connected to whatever caused the change in EPC, maybe you can just enjoy it and not sweat that extra 8%?

I have ran up my stats from Adsense into a statistics program, and the data appears to be artificially normalized. It started around the FL update. You can see it clearly on a chart. I have also noticed the filter that should allow you to filter out competitors, works intermittently. I believe that their servers get overloaded with requests and things start to fail. Like the competitor filter and the stats, and if this is true, I believe it would also include the money paid out. I know the competitor filters that I have work, because I have checked them out. The filter failing is something I just noticed over the last 10 days or so.

I think that when things start to get overloaded, they start sharing CPU time based on the number of requests your site makes for ads. i.e. a percentage The fewer the requests you send, the more likely the chance of seeing what I am talking about because you are a smaller bit than larger sites, thus you get less CPU time. It’s a numbers game like all stats.

Just my opinion in what my data indicates.

jim_w, I think you have something there. I've been saying this for a while. Google "adjusts" clicks and earnings and may collect either or both over several days and then dump them on your account on a day when you least expect it throwing all EPC, CTR and other tracking metrics completely off course.

That kinda negates the benefit of having channels.
