I know there is a limit of 3 ad units/3 link units per page. What I need to know is does Google automatically not show ads that go above this limit? I think I may have accidentally added 4 ad units, and oddly enough, they are all showing. EDIT: No, nevermind, one isn't showing! Can I get in trouble for this? Or can I leave it up to google to block the fourth ad? I would rather not mess with it because these 3 ads are on a sidebar, and then the fourth is on my main page. so, the only affected page is the main page. (which google just takes out one of the sidebar ads, which I prefer)
I wouldn't think so. Some of my blogs have the code for 4 units on a single page. If in doubt fire their support an email.
