How many ad units can be placed on a single page?
A. You can place 1 instance at most of each ad unit on a page. There’s no restriction on the number of ad units, we typically provide publishers with 6 ad units (728×90, 468×60, 300×250, 120×600, 160×600 and a 1×1 sub-sites ad), with more ad units generated based on specific (advertising and publishing) requirements.
