Page Impressions

How does Google count them?

[kidd]

Hello:

I have about ten channels created on Google, and I've seen that by making the sum of the independent page impressions on each channel I get the total Page Impressions of my account. This brought a question to my mind, how does Google count page impressions?

Now I see that if for example I have one page with three different ad units and a user visits the page, that will count for three page impressions, one for each ad unit. Is that correct?

Thanks

Go to your Adsense control panel and use the "Show data by" option click on help if you have questions. This tool allows you to view impressions by individual ad units or by page.
