I have a proxy site which has 329 / 292 / 180 unique users (last three days) at AdSense it's 125 / 37 / 83 impressions. This website also have some tips how to configure web browsers so just like my other websites 300 unique users should make about 500-600 impressions and here it's something wrong. Did anyone had same problem ? Firstible I thought that maybe ads are not displaying but i have preety high eCPM so it's not smartpriced, conversions must be well, so why so few page impressions ?
Google AdSense impressions are impressions your being paid\registered for, they will not equal your web hosting log data.
Oh I get it, thanks, since 3 years it's the first time I have less impressions then uu so it's something new for me
Most web server logs are inaccurate due to they count certian things as impressions that really aren't. I suggest using http://www.google.com/analytics for your web statistics, it almost always matches my adsense data 100%
