# Meta Ads Learning Phase

Every ad set goes through a learning phase while Meta figures out who to show the ad to. Until it exits, performance is unstable and CPA is unreliable. Underfunded or constantly-edited ad sets get stuck "Learning Limited" and never stabilise — a quiet, common cause of weak B2B accounts.

## Instructions

1. Fund each ad set to clear ~50 optimisation events per week
2. Pick a conversion event frequent enough to hit that threshold
3. Avoid edits that reset learning mid-phase
4. Consolidate ad sets so budget is not spread too thin
5. Judge performance only after the ad set exits learning

## The 50-Events Rule

- An ad set needs roughly **50 optimisation events per week** to exit the learning phase. Below that it shows "Learning Limited" and delivery stays inefficient.
- Budget floor follows from your CPA: if a conversion costs ~$20 and you need 50/week, that is roughly **$140+/day** for that ad set. Higher CPA → higher floor.
- Rough B2B floors: ~$50/day minimum for retargeting ad sets; enough on prospecting to generate ~7+ conversions/day toward the 50/week target.

## Choose an Event You Can Actually Hit

- If your true conversion (qualified lead / demo) is too rare to hit 50/week, optimise to a higher-funnel event (lead, landing-page view of the right depth, or Instant Form open) to give the algorithm volume, then use offline data to keep quality honest (see measurement).
- This is the central B2B tension: optimise to an event frequent enough to exit learning, but feed back quality so you do not just buy cheap junk.

## What Resets Learning (avoid mid-test)

- Editing budget significantly, changing the audience, swapping the creative set, or changing the optimisation event resets learning.
- Do not make these edits mid-test. Batch changes, then let the ad set re-stabilise. Constant tinkering keeps an ad set permanently in learning.

## Consolidate to Escape "Learning Limited"

- Too many ad sets split the budget so thin no single one clears 50 events. Consolidate audiences (broad + Advantage+) and ad sets so each gets enough volume (see campaign-setup, audiences).
- Fewer, better-funded ad sets exit learning and stabilise; many tiny ones all sit Learning Limited.

## Examples

Example 1: "My ad sets say 'Learning Limited' — what do I do?"
→ They are not getting 50 events/week. Consolidate ad sets, raise budget toward the floor (CPA x 50 / 7 per day), or optimise to a more frequent event. Stop mid-test edits that reset learning.

Example 2: "How much budget do I need on Meta?"
→ Enough per ad set to clear ~50 optimisation events/week. At a $20 CPA that is ~$140/day per ad set; scale by your real CPA and consolidate so budget is not spread thin.
