Hello, Is it legal to have more than 3 ad-units per page if they are different types? Let's say that I want to have like this: - 1 header ads - 1 link unit - 2 medium squares - 1 skyscraper Is there any problem. As I know (but I'm not sure) you should not have more than 3 of the same type on a single page. L.E.: Google Help Answer Thanks, Daniel Roșca
A "header ad", "medium square", and "skyscraper" are all ad units. You are allowed a up to three ad units on one page - they can be all the same format or one of each type, but only three total. A "link unit" is a link unit - you are also allowed to have up to three link units on one page.
You can only have upto 3 ad-units per page and not more than that untill you are a premium publisher authorised by google .
