You may place up to three AdSense-enabled units on one web page, if all of the following criteria are met:
- You're using DFP Small Business to serve only AdSense ads on a page.
- There are no delivering line items targeting an AdSense-enabled unit.
DFP Small Business will detect the multiple ad units and display an optimal number of highly targeted Google ads, unique to each ad unit on the page.
We encourage you to enable AdSense for your ad units to minimise unsold inventory and maximise revenue.
