Ep 7: Curated audiences: selling your first-party data signals

What do you know about your readers that no cookie can tell?

Curated Audiences is an IAB standard for sending your own segments, without user IDs.

Take recipes.example. A visitor has read six baking recipes this week. You do not send a user ID. You map that to a standard label: segment three seven two, desserts and baking, from the IAB Audience Taxonomy. In Prebid, the label goes into the user data field, with your domain as the source, and seg-tax four, which tells buyers which taxonomy you used. Bidders that support it all see the same label. A buyer looking for bakers can bid on it, or buy it in a deal. It is a label, not a cookie, so it works across browsers and apps. One caution: in some regions, sending user data needs consent.

List three things your site knows about readers, and find the matching taxonomy IDs.

Next: the IAB Deals API, ending deal-sync chaos.
