|Adsense Impressions 1/3 of those shown by multiple stats packages?|
Anyone else experiencing this problem?
They recently launched adsense ads on the site, and the adsense stats are showing only a third of the impressions as they get pageviews daily.
I'm tasked to finding out what's going on with this as I experienced it personally on a blog that I just put adsense ads on, as well (example: yesterday the blog got 1,006 pageviews and 461 unique visitors, but adsense only shows 347 page impressions?!?) Now, the blog uses Sawmill for it's stats software, so I know that of those pageviews, only 64 of them were from spiders or bots. So what is going on? Where are the missing impressions on Adsense?
Any help anyone can provide on this would be greatly appreciated!
I did some searches on webmasterworld.com before posting this, and found a number of threads with people having similar problems (and no resolution listed), but those were from 2004 and 2005. I tried paging through the last three pages of topics on here, and only found one post describing a similar problem.
How do folks explain this anomoly
I've experiencedthe same problem. I think some of it may be blocking software that never actually calls the ads, so google wouldn't know your site had an impression, your stats program would tho. Also I've noticed that sometimes the ads don't show on a page then after a refresh it does, I'm not sure it Google counts a page view when it doesn't show ads (just bg color)or not. I would assume not.
I'm trying to get a handle now on exactly how often the noscript tags are getting activated.
The other thing that can happen is if your targeting is off and you are getting PSAs. There is an option for an alternate ad in those cases.
Hope this helps
|some of it may be blocking software that never actually calls the ads |
Good point though I hope it's not that 2/3 of our visitors are blocking ads. It would be interesting to know what % of surfers do have the ads blocked.
I looked at my Google analytics and here is a number for whatever worth it is, 98.26% have java enabled. 81% are using I.E. 13% are using FF, just my .02 (sometimes more then a search payment) doh!
My personal guess is that it's spiders that are not identifying themselves as such. They can really rack up the page views.
P.S. From what I have seen, Google's reporting is very accurate. Sometimes delayed but everything gets counted.
Thanks everyone for the responses. I guess the general consesus is that there's no recent anomoly with adsense stats.
Again, thanks to everyone who tried to help on this one. I wish I had better news for my employer who was hoping it was a recent glitch and not representative of what he could expect on an ongoing basis..
Seriously, it's most likely spiders. I can't even count how many hit my site every day that impersonate MSIE and ignore the robots.txt file.
It can also be due to PSA's, but without accurate tracking (see my previous post) you will probably never know whether there's an actual discrepancy or not.
