Maybe it could be said that this way.
You can get away with ads that aren't clearly labeled as ads and that aren't spaced out very well... if there's only 2.
But if there's 9 you have a problem.
On the other hand you might be able to get away with having 9 ads on the page, if they're clearly labeled as "Ads" and spaced out well.
