In the Adstudio assistant
The assistant reads ads with Meta's rankings and format (image, video, carousel or catalog), and puts creatives on screen. It can also look at the images to describe what they show.
Meta Ads · Best creative
Which Meta Ads creative performs best?
The best Meta Ads creative is the one with the lowest cost per result or highest purchase ROAS against ads in the same ad set, with enough spend to trust it. Adstudio ranks ads within each ad set, adds Meta's quality, engagement-rate and conversion-rate rankings, and shows the creative so you can see why it wins.
The numbers that matter
What to read first.
- Cost per result by ad
- Within one ad set, so the audience is the same.
- Purchase ROAS by ad
- For Sales ad sets.
- Conversion rate ranking
- Meta's own comparison with competing ads.
- Video ThruPlays and completion
- For video creatives, how far people watch.
The method
How to break it down.
- 01Rank ads inside each ad set by the ad set's goal.
- 02Check spend: a winner on a tiny budget is not proven.
- 03Compare formats separately: image, video, carousel, catalog.
- 04Look at the winner's hook, offer and format.
