Analytics and adsense pageview is not same, not even closer! Why this?

I run a website and I have pretty good number of visitors comparing the time I spent on this site. But I have a problem. Actually I even don't know if it is a problem or not!
For the last 7 days according to Google Analytics, I had more than 94,000 Pageviews. But in Adsense, pageview count is less than 40,000! That means less than half of my actual pageviews are coming with adsense ads. I have installed adsense code on all pages of my site. So why this is happening? Could someone please describe this?

 

No one knows anything about it?

 

I was curious about the same thing happening on my site and did some research on adsense.

These are some of the reasons I've come to a conclusion with:

1) If the ads don't load before the user does an action then it doesn't count as a page impression (ie: user clicks on a link before the ad loads)
2) Many people use ad blockers in their browser, google is smart enough to know when their ads aren't be displayed so again this doesn't count as a page impression

Those are the 2 only things I know that may answer why your analytics or any other statistical program may not match that of your adsense. If anyone has more reasons please feel free to add to the list.

Hope that helps you mate!

 

Thanks you for the explanation. But it is less than half of my actual pageviews.

 

I wonder if it has anything to do with showing the same ad's on the page. For instance, if there were 2 of the same cell phone company ads shown by google on that page, would they only count 1? It'd be interesting to see, but I'm with you, my pageviews from adsense are way less than half that of my pageviews x (# of google ads on that page).

 

You got a good point here. If I start to calculate pageviews x (# of google ads on one page) then it will be 3 times than my pageviews! As I am showing 3 ads per page.

 

You can also try some other advertisers to just compare how many pageviews they see and are paying for. I am currently changing the infrastructure to my site and I am going to add 3 more ads from another advertiser to see the difference in what they payout. Let see what happens in the next few months!

 

It is all about how the two services count visitors and page views. Some discard bots like google and yahoo.

 

It is because the algorithm of the AdSense and Google Analytic is different. Google Analytic counts each and every visit at your site whereas, Google AdSense will only count those visit that matches their algorithm.

For example: If you have a website and in that the content is not similar as compare to the ad at your site. At that time Google AdSense does not count that visitor.

this is why there is a lot of difference.....
