Index Exchange details four addressability tools for buyers and publishers
Index Exchange published an article detailing its addressability solutions for advertisers and publishers, which aim to help target specific audiences with relevant ads. These solutions include Universal ID providers, Matched Audiences, ID Match Extension, and the use of Publisher First-party data for contextual targeting. The article explains how these tools enable the delivery of personalized ads in open market and deal ID scenarios, leading to potentially higher bids for publishers.
Key Takeaways
- Universal ID providers at Index can pass person-level or device-level IDs from data partners into DSP bid requests.
- Index says publishers using a Universal ID typically receive higher bids because buyers have more identity or contextual information.
- Matched Audiences lets buyers target audience files managed with specific Universal ID providers.
- ID Match Extension brings Universal IDs into cookie-based environments.
- Publisher first-party data can be sent in bid requests through Prebid’s First-Party Data module or the OpenRTB user.data object.
Why It Matters
Index Exchange is formalizing a menu of addressability options that tie identity and context directly to bid requests, which matters for how buyers target audiences across open market and deal ID paths. The mix of Universal ID providers, Matched Audiences, ID Match Extension, and publisher first-party data shows how the ad tech stack is trying to preserve targeting options even as identifiers vary by environment. A specific signal to watch is which integrations Index supports most broadly — the article calls out Prebid, OpenRTB, and the OpenRTB user.data object for contextual data.
