Which Meta Ads placement performs best: Feed, Stories or Reels?
The best Meta Ads placement is the one with the lowest cost per result for the ad set's goal, which you only see by splitting each ad set by placement. Adstudio splits results by publisher platform and position — Facebook Feed, Instagram Stories, Reels and the rest — and keeps the comparison inside one ad set and one creative format.
The numbers that matter
What to read first.
- Cost per result by placement
- The comparison that decides placement.
- CPM by placement
- Cheaper impressions are only better if they convert.
- Link CTR by placement
- Shows whether the creative suits the format.
The method
How to break it down.
- 01Split each ad set by placement.
- 02Compare cost per result, not CPM alone.
- 03Check the creative fits the placement: a square image in Stories is not a fair test.
