the entire meta ads algorithm explained in 21 mins

A breakdown of how the Meta Ads algorithm selects which ads to show users, covering the four-step process: retrieval, light ranking, heavy ranking, and the auction.

The core value equation (bid × estimated action rate + user experience) governs heavy ranking. Additional topics include the Andromeda update's impact on broad targeting, the learning phase myth, signal quality via Conversions API, creative diversity strategies, and a candid take on how Facebook's profit motives affect advertiser outcomes.
