Ad Delivery
What is ?
Ad Delivery refers to the process by which Meta distributes your ads to users across Facebook, Instagram, Messenger, and the Audience Network. After you publish a campaign, Meta's delivery system enters your ad into billions of real-time auctions, evaluating your bid, estimated action rate, and ad quality to determine when and to whom your ad is shown. The delivery status (Active, Learning, Learning Limited, Not Delivering) indicates how effectively Meta can optimize your campaign. Understanding delivery mechanics is essential for diagnosing underperforming campaigns.
Example
You launch a conversion campaign but notice the delivery status shows "Learning Limited" after 5 days with only 15 conversions. Meta needs approximately 50 conversions per week per ad set to exit the learning phase. You consolidate three ad sets into one, broadening the audience from 500K to 2M, and delivery stabilizes within 3 days with a 22% lower CPA.

Optimization Tips
- 1
Check the Delivery column in Ads Manager regularly, "Learning Limited" means Meta cannot optimize your ad set effectively.
- 2
Avoid making significant edits during the learning phase, as each edit resets the optimization process.
- 3
If an ad is not delivering, check for audience overlap, low budget relative to bid, or ad policy violations.
- 4
Use the Delivery Insights breakdowns (auction overlap, audience saturation, auction competition) to diagnose delivery problems.
