Google ALLOWED MULTIPLE Publishers ad code in a page / site.

[bimo]

For those who are still dont know this, Google has ALLOWED MULTIPLE Publishers ad code in a page / website. As long as the maximum number of ad units per page will remain the same (3 ad units and 3 link units)

A number of publishers have asked us if it's acceptable to place multiple publishers' ad code on the same page or site. Often they'll run into this issue when two AdSense publishers manage a site together and both want to display their ads, or if a site owner hosts content and ads from other publishers on the same page as their own.

The answer is that yes, we do allow this...
