Personalized advertising (formerly known as interest-based advertising) is a powerful tool that improves advertising relevance for users and increases ROI for advertisers. In all our publisher products, we make inferences about a user’s interests based on the sites they visit or the apps they use. This allows advertisers to target their campaigns according to these interests, providing an improved experience for users and advertisers alike. Learn more about our advertiser policies for personalized ads.
Google considers ads to be personalized when they are based on previously collected or historical data to determine or influence ad selection, including a user's previous search queries, activity, visits to sites or apps, demographic information, or location. Specifically, this would include, for example: demographic targeting, interest category targeting, remarketing, targeting Customer Match lists, and targeting audience lists uploaded in DoubleClick Bid Manager or Campaign Manager.
Non-personalized ads (NPA)
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 personalized targeting, including demographic targeting and user list targeting.
