my logs not correlating with adsense stats

I have 3 domains running from different directories off a single webhosting account. i have adsense code on all the pages with 2 adsense ad blocks per page.

my logs using awstats shows 14,000 page views for all 3 domains total, however adsense reports only 2,200 page impressions. any idea why such a large discrepancy?

Do you see many PSAs on your site? I have some difference between logs and AS, but in no way to an extent that you describe. 14,000 vs. 2,200 seems a bit hefty IMO.

awstats is inaccurate, use a better stats tracker.

I'm not familiar with awstats - is the 14,000 definitely "page views", or might it be "hits". Does awstats list page views and hits separately? If there is only one number it is more likely hits, in which case your stats make sense.

A hotlinked image in awstats is counted as a page view.

The stats makes sense, therefore: 14,000 hits to 2,200 page views is not far off the ratio for our site.

It's NOT that awstats is inaccurate. It IS that the internet is a stateless protocol. There is no way to accurately track the stats you want. Proof: try 10 different stat programs - awstats, web trends, webalizer, analog, etc and you will get 10 different results. Often drastically different results.

Add to that, some visitors have javascript turned off so they are not going to show up in your adsense stats.

no, awstats is inaccurate, you won't see a 14000:2000 ratio with any web hosted counters.

mzanzig - no...virtually no PSAs

dzcap - i used webalizer as well as downloaded the logs and analyzed it using a client side log analyzer...same result.

21_blue - its page views, hits are 70,000

could it be due to browser caching?

Both awstats and webalizer parse the server or something, if you want accurate stats, you need to use a web based counter.

In that case, there's something else behind it. In your position, I'd want to get to the bottom of it so that I can understand what is going on at my site. Although I accept dzcap's point about reporting variations, the ratio here is too big to put down solely to inaccuracy.

It's worth noting that, apart from delays in reporting, Adsense stats may not be exactly the same as log analyses, but they are usually in the same ballpark (not a 600% difference). There are other factors such as pages cached on computers or at google that can make a difference, but again only a percentage.

What are your visitor numbers - are they nearer the awstats or Adsense figure? It depends on the nature of your site, but if your visitors are, say, 7-10,000 then the awstats figure is probably right, and you are probably displaying pages with no adsense ads on, for some reason - perhaps search engine spiders are doing somethign odd to account for the difference (our stats package automatically removes spider accesses). If visitors are down at around 1,000, then the page views in awstats are probably misleading.

21_blue - that is a good analysis.

my unique ip visitors are average 1,900 day which is near the adsense page impressions BUT also i'm sure that each of the vistors are seeing at least 5 pages because i offer lots of free stuff, hence the page views total seem to be in the awstats range.

so could it be that google is counting only the unique ips as page impressions?

Ha! I'm "sure" that my visitors are seeing more than 5 pages because the content is such high quality :-))

Alas, a detailed analysis of user movements through the site disagrees. There are some people who spend a lot of time at our site, but overall average is brought down by the number of people who exit after the first page. Fortunately, a lot of them do that via Adsense, these days, but 5 page views per visitor seems very high when compared with the rigorous data analysis we've done on our site and the typical page views I've seen reported by other sites.

In fact, a ratio of 2,200 page views to 1,900 visitors seems quite normal, and I trust Adsense stats to be near the mark, so, I'd look more at your awstats and investigate why it is reporting so many page-views. Are there pages without adsense? Do you use software that tests the links on your site without displaying ads? Are there lots of spiders visiting your sites? Are you doing a lot of uploading or do pages get updated a lot? Etc. etc..

"a ratio of 2,200 page views to 1,900 visitors seems quite normal, and I trust Adsense stats to be near the mark"

i will install a counter on a few pages just to see if it tallies with the adsense, maybe the logs are in question......well, thanks for the info!

If you are going to change your pages, other useful things to do are to put a small image at the bottom of every page alongside the web counter, and download some expensive log file analysis software on demo. That way, you can see how many times that image is accessed vs the web counter vs awstats vs adsense vs another package. Also, remember that an Adsense day is according to California time and the Adsense reporting is not realtime.

centaurus,

What exclude filters do you have set in awstats?
