I'm an adsense veteran. but this was just surprising to me. Is this even legal: http://www.suite101.com/content/an-introduction-to-google-finance-a72588
Google allows max 3 ad units per page to publisher but even if you more than 3 ads units it will show only 3 other will be show white space suite101.com is seems to be premium publisher of ads so they may be allowed to by adsense
Premium Adsense publishers makes much more money than common Adsense accounts. If your site receives more than 5 million search queries or 20 million content page views a month, you may qualify for AdSense premium service.
Dude, you difinitely not read their policy carefully, here is the link:https://www.google.com/support/adsense/bin/answer.py?hl=cn&answer=48182
Google adsense will allow only 3 max bigger ad-boxes for normal adsense accounts. But for premium accounts it is unlimited & depends on the space availability on the website. Actually for normal adsense accounts we can put a maximum of 6 ads. Out of these 6, only 3 are large boxes(Rectangular skyscrapper, square, wide-leader board ) and remaining 3 are smaller boxes where only one line ads will be displayed.
yes...those add's are not normal adsense account add's those are premium account add's. check the add code it's very strange.
