Publishers may sell inventory for users who haven't given consent to be served personalized ads. In order to buy this inventory, you need to use a line item (or line items) that don't use any types of personalization features and thus are eligible to buy non-personalized ad inventory.
What are non-personalized ads?
Non-personalized ads are ads that are not based on a user’s past behavior. They are targeted using contextual information, including coarse (such as city-level) geo-targeting based on current location, and content on the current site or app or current query terms. Google disallows all interest-based audience targeting, including demographic targeting and user list targeting.
