If I had 3 adsense ads on a page, everytime the page is loaded on a visitors browser, does the adsense report state that as 1 impression or 3 impressions? Tried looking this up in the FAQ but nowhere to be found.
It counts as 1 impression in your main Adsense stat window, but it counts as 3 if you use the advance report's "show data by individual ad units" option.
I've got different results, The overview page, calls up an impression, as per ad group. So three on a page, means 3 impressions per page load. I haven't really looked into this, just recalling an observation I made a while back. later, tom
