Is There a Creative Similarity Score on Meta?

The Meta pages read for this entry do not document a creative similarity score. They do document a “creative similarity” insight in account insights, and they separately document auction overlap and creative fatigue. As checked on 3 October 2026, none of them gives a similarity score, a threshold or a count of similar ads.

What does Meta document about creative similarity?

Meta’s page on account insights in Meta ads reporting lists two creative insights: creative fatigue and creative similarity. It says “creative similarity occurs when the images or videos in your ads appear too visually identical.” Meta says this can lead to creative fatigue and increase your cost per result, and it recommends creating new ads with unique creative.

Meta states two conditions. The insight is based on static ads active in the last 28 days, and it does not include Advantage+ catalog ads. The page also says the feature may not be available to you yet.

What does that page not say?

As read on 3 October 2026, the page does not say how “too visually identical” is measured. It gives no score, percentage or threshold, and no count of similar ads. It ties similarity to fatigue and cost per result, and it does not describe a separate delivery rule. If you have seen a similarity figure elsewhere, the pages read do not give one.

Which pages did this entry rely on?

The pages read were the account insights page, the creative fatigue recommendations page, Understand auction overlap, Campaign auction overlap, About managing ad volume, About Advantage+ sales campaigns, and Significant edits and learning phase.

Searches of Meta’s help centre on 3 October 2026 used several phrasings, including similar ads, duplicate ads with the same creative, creative diversity, creative similarity score, near-identical ad variations, ads with the same image or video, and similar creative recommendations. Among the pages those searches returned, the account insights page is the only one that defines creative similarity. The ad volume and Advantage+ sales pages advise diverse creative assets and give no similarity rule.

Is auction overlap the same as similarity?

Meta documents them on separate pages. Meta says that when you create ad sets with overlapping audiences, several ads from your Page may enter the same auction. When 2 or more ads from the same advertiser enter one auction, Meta chooses the ad with the highest total value to compete, and the other ads from that advertiser are not considered in that auction.

Meta says overlap can limit delivery “when ads from the same advertiser share the same audience or assets”. The page does not say how much sharing counts. Meta’s campaign auction overlap metric counts ad sets in one campaign that entered the same auction as another ad set in that campaign. It counts ad sets, not creatives.

How does Meta’s creative fatigue status work?

It is a different test. Meta says it considers “all recent exposures of the ad’s image or video, including those from other campaigns from your page”, and your ad’s cost per result. You see creative limited when cost per result is more than your past ads but less than twice as much, and creative fatigue when it is twice as much or more. Those are Meta’s status rules for fatigue, not a similarity score.

Meta’s recommendation there is to create a new ad with a new image or video “that is materially different from the original creative”. As read, the page does not define “materially different”. Meta says the feature is only available for ad sets with one creative, and not for Advantage+ catalog ads, dynamic creative or Advantage+ app campaigns.

What can you check in your account?

1. Look for the creative similarity and creative fatigue insights in account insights, if Meta has made them available to you.
2. Check the Delivery column for a creative limited or creative fatigue status on your ad sets or ads.
3. If ad sets share audiences, check auction overlap using the options on Meta’s overlap page.
4. Know the cost of adding creative. Meta lists adding a new ad to your ad set as a significant edit, and says only a significant edit makes an ad set re-enter the learning phase. Meta says the learning phase can lead to less stable performance and a higher cost per result.

Whether new creative changes your results is not documented, and Meta gives no count to aim for.

FAQ

How does Meta measure creative similarity?

Meta’s pages read do not say. The account insights page says similarity occurs when images or videos “appear too visually identical” and gives no formula, score or threshold. As checked on 3 October 2026, no other page read for this entry defines it.

Is creative similarity the same as creative fatigue?

Not in Meta’s wording. The account insights page lists them as two separate creative insights. Fatigue is an audience seeing the same creative too many times. Similarity is images or videos that appear too visually identical, which Meta says can lead to fatigue.

Does Meta say how many different creatives to run?

Not as a target. Its ad volume page says to decrease ads per ad set while keeping diverse creative assets per ad set, and that one ad can contain up to 10 creative assets. Those are a tactic and a stated maximum, not a recommended count.
