site statistic and adsense

[simon3]

Hello
My website statistic show that i have 500 page view but google page impressions show only 100.
yesterday i had 800 but google show only 300.
is it possible?
it used to show the same numbers but now it's all different.
The earning is also down by 90%.
is anyone know why?

What Google means by "Page impressions" is actually ad block impressions. If you have 2 ad blocks on a page, then your "page impressions" will double. Your web stats *will* differ from what Google says because of this. I got confused by that one at first.

But also, as someone else pointed out, there is ad blocking software out there that is blocking adsense ads by default.

And PSAs aren't counted.

And numerous blind to javascript bots may be grabbing your pages too. They won't call for the js.

Yep, that's a point; if it's a new site, your biggest user is probably Google.
