Targeting and data

Third-party cookie

Definition

A cookie set by a domain other than the one being visited, historically used to track users across sites.

Why it matters if you sell your own ads

The long decline of third-party cookies makes network and programmatic targeting less effective, which quietly raises the relative value of selling your own inventory directly.
