Meta is gradually rolling out a new ad-delivery algorithm called Andromeda. This algorithm fundamentally changes how ads are evaluated, optimized, and delivered. The change isn't only about how the system works under the hood — it directly affects how campaigns should be set up today.

Andromeda is an advanced AI ad-delivery model that works with far more signals than earlier algorithms, which lets it match the right ad to the right user with much greater precision.
