Improved reporting: ad unit impressions vs. page impressions
We've added new options to your reporting page, allowing you to select from page impressions or ad unit impressions when generating your performance reports. Not sure what this means? Check out the AdSense Support center for an explanation of page impressions versus ad unit impressions.
In addition, your browser will now remember your prior report settings each time you select a report. If you have a favorite report that you run often, you're going to love this feature!
I tried to check certain channels, where a site has only 1 block and 1 AdLink, but clicking on Channel greys the page/adblocks choice.
I think AdLink blocks are counted not as an impression.
If an AdLink Block would count as an impression,
the ratio between page views and AdImpression views would be much greater at me.
