The learning phase is the period when Meta algorithm is figuring out how to best deliver your ads.

Understanding the Learning Phase

What Happens

When you launch a new ad set or make significant changes, Meta explores different audiences, placements, and delivery patterns. Performance may be unstable during this period.

How Long It Lasts

The learning phase ends when an ad set reaches approximately 50 conversion events within a 7-day period. This typically takes 3-7 days but can be longer for low-volume accounts.

Why It Matters

During the learning phase, cost per result may be higher and results less consistent. Making significant edits resets the learning phase, so patience is important.

Best Practices

  • Avoid frequent edits to new ad sets
  • Set budgets that allow for sufficient conversions
  • Consolidate ad sets where possible
  • Give campaigns time to optimise before judging performance
