Target ads

About targeting

Advertisers or buyers typically want to reach an intended audience or demographic with their campaigns. Targeting helps you build expressions that determine how and where ads serves to reflect the goals of your advertisers or buyers. Targeting can be broad or granular.

Key concepts

Some key concepts you might want to familiarize yourself with:

Typically, targeting is applied to line items or proposal line items. However, targeting is applicable to many parts of Ad Manager—Protections and unified pricing rules, for instance, features that help you manage inventory in the Open Auction.  Wherever you use targeting, concepts and behavior are the same across Ad Manager.

Targeting restrictions

You may not pass any user-identifiable data (including names, addresses, or user IDs) in targeting. Mask this information using the encoding method of your choice, and ensure traffickers know how to decode values when setting up a line item.

Ad Manager doesn't read your site's cookies and doesn't have connections to your web systems. JavaScript tagging is the only way to pass information to Ad Manager from webpages. You must pass information to Google Ad Manager on every page because the information isn't stored with the user.

Google Ad Manager doesn't share information with other publishers, so there is no built-in pool of demographic data to target.
