About the Learning Phase
Meta · Meta Business Help Center Free Beginner
This is Meta's own definition of the learning phase and the roughly 50 optimization events a week benchmark our short answer is built on, so you're reading the rule from the platform that enforces it, not a paraphrase of it.
- An ad set needs about 50 optimization events within 7 days to exit the learning phase and stabilize delivery.
- A 'significant edit' (large budget change, new creative, audience change) resets the clock and restarts learning.
- Costs and delivery are typically less stable and less efficient while an ad set is still in learning.
