Questions on google adsense guildlines please help

Hello,
I read google adsense policies and see this as in the first line.
Up to three ad units may be displayed on each Web site page.

What does it really mean?
does it mean, we can NOT put more than 3 ads on a page?

Thanks.

 

If you put more then three ad blocks on a page, it won't display anyway, but yeah three is the max.

 

Yea, 3 ad blocks per page and that also includes some other ads also (ex. yahoo)

 

Well you couldnt have other contextual advertising on the page regardless.

 

You meant, if I put more than 3 SAME ad blocks, it won't display.
If I have: 428x60 banner, 160x600 on left, 160x600 on right, search box, and link text ON ONE page, then, they wont' display....

Mine display, but I am not sure if it violates the goodle rules or not.
Thanks.

 

These are the ad blocks so if you put a forth in there it wouldnt display.

You can have the setup that you suggested.
