Adsense Page Impression Not accurate?

The page impression number is almost 15% less than what is shown in Google Analytics? How can I explain this? I was thinking the bounced page didn't count, but the bounce rate is much higher than 15%, so not an explanation.. Any other explanations? Or it is just my site problem with loading Adsense, sometimes it is slow though?

 

Yes, I believed there are some delay in refreshing the data in Adsense. This is my guess. Thanks

 

The data from adsense might have some delay compare to google analytics

 

The final daily number is off.. Not the delay.. Anyone has similar experience? I was thinking also people click "back" before the ads is even loaded.. Am I right?

 

it can be easily explained... its simple Google may not showing ads for every impression of your site or may be showing Public Ads which carry no money.

 

some difference and variation will always be there between aalytics and othe rprograms

 

it takes some time while analysis programs works

 

right but hope problem wont last for long

 

This does work

 

i can see that today google not calculate my impressions

 

Suppose if you had installed analytics code in footer. Now if a user exits your site before footer code is executed then analytics cant consider that impression.

 

To the best of my knowledge, don't ad blocker programs stop the execution of certain Javascript code?

 

I think it's because people use programs like adblock, etc as bsherwood says.
