Adsense report query:cpm and CTR

[ata.online]

Referring to the adsense report:

Page Impressions
Clicks
Page CTR
Page eCPM
Estimated earnings

These are the headings in the adsense account.

Can someone explain to me where can i find the information on 'unique visitors' because that is what counts?
Is it the page impressions, but one user can generate hundreds of page impressions?
The page CTR gives only a percentage overview

Thanks.

Hi,
You can try google webmaster tools and add a small script from there.
You get not only unique visitors , also looots of information about the
site stats.
thank you

Ok, thanks. But i would expect adsense report to include unique visitors. It just sounds bizarre that they would not include this.

I just tried to add the meta tag from webmaster tools onto homepage under main index template. But does not seem to work.
It was after header but before body section.
