Meta's algorithm has become extraordinary at finding buyers — if you feed it enough signal. The modern craft is less about audience settings and more about creative volume: multiple angles, hooks and faces in market at once, each teaching the machine something about who responds.
Every ad also has a lifespan. Winners fatigue — frequency climbs, costs creep, and the account that depended on one great ad discovers it built its house on a single beam. The answer is an antifragile system: enough live creative directions that no single fatigue event can hurt you, refreshed on a rhythm, tested one variable at a time, winners duplicated rather than edited.
Under it all sits the pixel: retargeting layered from first visit to final sale, audiences built from your actual buyers, and measurement that separates what Meta claims from what your bank account confirms.
