"Putting 3 adsense blocks (large rectangles or small rectangle) after each other" IS there is a Problem with TOS ??? Thanks in advance for any help
It's not really against their TOS (since you are still in compliance with the number of ads on your page), but from experience, I know for one that Google will only let 2 of those ad blocks load. Better use a different ad size for the 3rd one..
not at all, besides google has a new rule that ads only show for 3/page only. no matter what ads you put on your web page.
not against TOS, but remember that the highest ad on your page has the best payouts. so try to limit your ads to 1 block
