So I accidentally clicked on Google's magnifying glass (Web Preview) after doing a site:www.example.com search of one of my sites, AND, I saw Adsense ads being displayed in some cases. Mostly the ad locations are simply white'd out, but not always.
This could certainly be increasing ad impressions enormously! A topic of another thread.

Amazon renders HTML in an IFrame. If Google does not render IFrames many website's headers and footers won't show.
Regardless this means Google's Web Preview will be producing numerous undesired impressions in Adsense, but they will also be dynamically loading servers like Amazon's.
Frankly I can't understand why there is partial rendering of Adsense ads. It seems like a big bug.
I'm tempted to try implementing NOSCRIPT tags to fill in the ugly white background that shows up wherever there were Adsense ads.

Yep, it's been like this for me (on my sites) since day 1 when web previews started showing.
My AdSense ad impressions are always higher than the number of visitors in my Analytics, suggesting that a non-Human is executing the AdSense ads (I think so, anyway?). This could be the reason for it.
