Set up AdSense in Google Ad Manager
You can provide AdSense buyers with greater access to inventory to serve ads. This can help monetize every impression in your network and generate revenue. You can set up AdSense in Ad Manager:
Use network level when you want all or most of your ad units available to AdSense buyers.
Activating AdSense for your network shows all ad units in your network as available to compete with bids from AdSense buyers. You may manually deactivate individual ad units from being available to AdSense.*
Use ad units when you only want smaller portions of your ad units available to AdSense.
Activating AdSense for ad units only shows individual ad units as available to AdSense buyers.*
Use line items when the AdSense line item type is enabled for your Ad Manager network
AdSense competes for ads similar to Ad Exchange, but AdSense doesn't serve on mobile apps.
* When AdSense is enabled at the network or ad unit level, ad units automatically serve all relevant ad types and use the optimal ad styles. This includes automatically selecting the best colors and fonts for the context in which the ad unit is serving an ad. You don’t need to manually manage styles.
