Fledge - Definition

Google’s First Locally-Executed Decision over Groups Experiment (FLEDGE) is Google’s proposal to measure the effectiveness of Google’s TURTLEDOVE auction mechanism as being a viable replacement for the interoperable identifiers that support the decentralized, open web. FLEDGE is based on concepts from the TURTLEDOVE proposal (i.e. it operates by making ad auction decisions in the browser itself, rather than at the ad server level), but includes feedback from other proposals, including Criteo’s SPARROW proposal.
