Adsense vs Analytics , Who tells the truth

[monkeysurfer]

I have a proxy site up for a month now.
In the last week the google showed me some strange results:
Date - adsense impressions - Analytics page view
Thu,March,29- 719 -1728
Fri,March,30- 691 -2438
Sat,March,31- 477 -721
Sun,April,1- 207 -500
Mon,April,2- 429 -1761
Tue,April,3- 465 -787
Wed,April,4 - 472 -569

So why did it happened? Is this normal? Why I had so many PV but no impressions? and my earning hasn't dropped anyway.Although I have been playing with the adsense codes but I don't understand why should google record the traffic with analytics and don't show any ads.

It is obvious that adsense bot was taking time to determine what ads are suitable for your site. That's why it did not show ads for every page view in the beginning. But now, google knows what ads your site can show.

Adsense Impressions only shows how many time adsense adblock appears while analytics shows how many time page displayed. These are two different things and don't expect both should be same.

Well it's a month my site is up and google should know what ads to show.
And why it showed more 700 impressions then? If google doesn't know what to show why did it showed the 700 impressions?

Because it is per page not per site. Contents of the page count.
Also, it is different from a country to another.

You might well be getting a lot of PSA ads shown to foreign visitors, which AFAIK don't show up on AdSense reports.

many internet users use software to block ads. Now, with firefox, is very easy to install adblocker, just go to plugins, select adblocker, install and then restart browser.

I concur with thoughts of 'thedark'. Impression won't be counted if they are not served.

this is a popular adblocker that may keep users from seeing all external ads.
