Understanding the Learning Phase
Quick answer
After you launch a new campaign, ad set or ad, or make a big change, Meta and Google spend a while learning who to show it to. Results swing more during that time. Leave new things, and anything you changed recently, alone for about 7 days before you judge them. Agency AI does the same: it makes no budget or target ROAS recommendation for a campaign in its first 7 days.
Getting out of the learning phase isn't essential. Ads still in learning can sell well, and learning is not a reason to cut the number of ads you run.
Meta
An ad set leaves the learning phase after about 50 optimization events (usually purchases) in 7 days. Big edits restart it.
If an ad set can't reach that, Meta labels it Learning Limited. The math: daily budget × 7 ÷ cost per purchase = purchases per week. Under 50, it stays in learning.
While an ad set is learning, cost per purchase usually runs higher and daily ROAS swings more. Judge it on a week or more of data, not a single day.
What restarts Meta's learning
- Big budget changes (more than about 20% in one edit is the usual rule of thumb)
- Targeting changes
- Bid strategy changes
- Adding a new ad to an ad set, or editing a live ad's text or creative
- Changing the optimization event
- Pausing for 7 days or more
When you click Edit on a live ad in Manage ads, Agency AI warns you that the edit resets learning and results may fluctuate for 24 to 48 hours.
Learning Limited isn't a verdict
In 2026 you don't need to leave the learning phase to get results. Plenty of ad sets stay in learning or Learning Limited and still make sales. Judge them on results, not on the label.
- Don't pause ads or cut the number of live ads to reach 50 events. Your Agency AI campaigns run several ads on purpose.
- If ROAS is above your break-even over a week or more, leave it running.
- If results are weak after a week or more, look at budget and creative. Ask your AI Strategist: "Which of my Meta ad sets are below break-even over the last 14 days?"
Google Performance Max
Google's bidding settles over 1 to 2 weeks after a launch or a target ROAS change. Conversions keep filling in for several days after a click, so the last few days always look weaker than they'll end up. A high target ROAS holds spend back. If Google is spending slowly, see Why is Google spending so little?
What Agency AI does
- 7-day hold. No budget or target ROAS recommendation for a campaign within 7 days of its creation or start, or within 7 days of a budget or target ROAS recommendation being applied to it.
- Pause recommendations aren't held. They can appear at any time.
- Only Apply starts the hold. Changes you approve on an AI Strategist card, or make in Manage ads, Meta Ads Manager or Google Ads, aren't counted.
So an empty Ad Performance Recommendations section in your first week is normal. See Understanding Recommendations.
When to wait, and when not to
The 7-day "leave it alone" rule is for new campaigns, ad sets and ads, and for the week after a change. It doesn't mean an established campaign is off limits. If something has run for weeks and is wasting ad spend, act on it. Message your AI Strategist: "Cut the ad with the highest cost per purchase." You approve the change before it runs.
Budget levels, and when to skip remarketing: Recommended minimum budgets.
