Well I've been with Google for 4 years and have some buddies of mine who work there and what your seeing is the front-end, am I encouraging you to click on ads? Nope the other pages don't do that either they just realized truths because of data analysis like: Users in india like the background to be green and the ad title to be pink but only on a time zone of +7 EST and on a Thursday and for only 9 hours.

Your multiple A/b Split tests, Multi country view is spot on when looking at ad units. Imagine trying to have 1 ad unit for both japanese and a US website.
