Addressability
Refers to how much targetable supply we can make available to demand.
Identified Impressions
Impressions that can be tied to a single identified consumer in the bid
stream. Today, this is done with 3PCs or first - party data delivered across
other identifiers ( eg , LiveRamp RampID , PreBid ShareID , etc.)
Non - identified impressions
Impressions that do not have a cross - domain identifier attached and can
only be targeted via group / contextual / 1P ID targeting.
Google's Privacy Sandbox
Google's Privacy Sandbox invites proposals to solve for 3PCs loss. The
result has been proposals like FLoC , FLEDGE, and other others which
focus on group targeting vs. individual targeting. The groups are created
based on browsing behavior or other factors. What the final outcome of
this will be we don't yet know, but we do know that Chrome will support
Sandbox initiatives and that will impact how to plan and buy media.
