Same thing here. I have brought it up in a couple of threads but I am missing up to 50% of the clicks adsense is reporting..
I guess I would rather them be messing in my GA account than my Adsense ;)
Why would AdSense ever synch with Analytics?
One visitor with a banner blocker blocking AdSense and it's out of synch.
Also, if your site allows caching, AdSense displays in search engine cache pages which are outside the scope of your domain which may/may not show in Analytics even if it gets a page impression, unsure on that one.
I don't expect them to sync exactly, but in the past the numbers have shown roughly the same --- Adsense might say $100 earnings while Analytics only tracked $90 of those earnings for example. Not a big deal. But the discrepancy is now much larger, dropping to Analytics only catching about half the earnings last week and now only about 1/3 over the weekend.
In some ways, it doesn't matter if the overall numbers sync, but if you're interested in checking earnings by page and you know you're only seeing 1/3 of the total earnings, you really have no idea which pages are performing better, because there's no guarantee that the few results you are seeing are even proportional --- I might be seeing all the earnings for one page that actually earned less while seeing none of the earnings for a page that in reality earned more.
It'd be nice, but Analytics isn't really good for anything but trends anyway, because it's inaccurate across the board.
Me, if I want reports, I use my own channel data and Excel.
I have the same problem. Since March 17th (thursday last week) all my sites in Analytics started to show only about 50% of the actual AdSense pageviews and earnings.
Normally it is about 5% ~ 10% lower.
Last week Google implemented the faster AdSense ads (that's what they wrote on their blog):
And since then Analytics is out of sync with AdSense.
Perhaps the maintenance yesterday solved this problem.
Same thing here.
I noticed that too.
Noticed the exact same thing here. Strange, maybe it's just a data thing. I use an external adserver to serve adsence which somehow tracks click, so i use that instead of analytics
Seems they are aware of this bug and are working on fixing it, here's the official message on GA blog:
|Users of the AdSense reports inside of Google Analytics may have noticed that there have been discrepancies between the AdSense reports in Google Analytics and AdSense since March 16th. We’re aware of the issue and a fix is being rolled out at this time. The cause of the issue is not related to the new version of Google Analytics. |
Seems like they fixed it. My valley of discrepancy has disappeared!
From the Analytics Blog
|Update: 3/22/2011 5:15pm PST - A fix for this issue was released early this morning. It will take a few more hours for the fix reach all users. AdSense reports should be working normally after that. Unfortunately, we are not able to reprocess the data that was affected by this issue. |
This has not been fixed. Many Webmasters are having the exact same issues
