What "too similar" means (and why it costs you)

When you launch five versions of an ad that share the same hook, the same offer and the same format, you haven't tested five ideas. You've tested one idea five times. Meta's own guidance pushes advertisers to diversify creative, and its engineering team describes Andromeda, the system that picks which ads to show, as built for a much larger volume of creative.¹

You'll often read that Meta merges near-identical ads under one "Entity ID". Meta hasn't documented that mechanism; practitioners infer it from how delivery behaves. What is easy to see in any account is the result: one or two ads take most of the spend and the rest barely run. Our explainer on Meta Entity IDs separates what Meta has said from what people assume.

The changes that make an ad a different idea are structural: the hook, the angle, the format, the persona or creator. Changing a background colour, a font or one word in the headline usually isn't enough. Triple Whale's audit scores exactly these kinds of dimensions, which is a useful way to think about it even if you never use the tool.³

1. SellTheClick: best for checking versions before you launch

What it does: you upload the versions of an ad you plan to run, and it shows which ones Meta is likely to treat as the same ad. It runs two checks. A picture match compares the images using CLIP image embeddings, so the same pair of images always gets the same score. An AI read then judges whether the ads say the same thing. The report labels which result came from which check. The similarity checker is free to try with no account.

Also included: a where-it-breaks diagnosis for live ads (before the click, after it, or on price) from numbers you paste from Ads Manager. Higher plans add a comparison with a competitor's longest-running ad and three new angles to test.

Price: Standard $29/mo, Rampup $79/mo, Pro $149/mo. Signup gives 1,000 free credits.⁷

Limits: built for Meta ads only. It doesn't connect to your ad account, so it judges the creative you upload, not your live delivery data. Team seats on Pro are listed as coming soon.

2. Triple Whale Creative Diversity Audit: best free check on live ads

What it does: you enter a website URL, and it pulls up to 80 active ads from Meta's public Ad Library. It tags them across six dimensions (themes, formats, copy angles, creators, hook styles and personas), scores each dimension out of 10 and averages them into one diversity score, with recommendations.³

Price: free. No Triple Whale account or ad account access is needed, though the form asks for your name and email. You can also run it on a competitor's website.

Limits: it only sees ads that are already live in the Ad Library, so it can't check versions before you launch them. It scores your whole set of ads, rather than telling you which two specific ads are too alike.

3. Meta Creative test: best free way to give each variant a fair run

What it does: inside an existing campaign, you can make 2 to 7 copies of an ad, swap in new creative, and set aside part of the budget for the test ads so each one gets delivery. Meta suggests using no more than 20% of the budget. Winners keep running in the same campaign, so delivery learnings aren't lost.²

Price: free in Ads Manager.

Limits: it only works with the Highest volume bid strategy, and Meta shows no confidence level on the results. It doesn't tell you whether two variants are too similar. It tells you which one performed better, after you've spent on both.

4. Alison.ai: best free best-practice score for video

What it does: its free Preflight Plus tool scores a video against Google's ABCD framework and Meta and LinkedIn creative best practices before you spend, in about 30 seconds, with no card and no connected ad account. Paid plans add creative tagging, competitive analysis, a creative fatigue detector and AI briefs.⁶

Price: Preflight Plus is free. Paid plans (Essential, Pro+, Enterprise) are sold through a demo, with no public prices.

Limits: a best-practice score tells you whether one video follows the rules. From Alison.ai's published pages, it isn't a comparison between your variants.

5. Motion: best for tagging everything you've already run

What it does: Motion connects to your ad accounts, watches and tags every creative you've run, and gives you creative analytics and an ad leaderboard. Its AI also writes briefs, hooks and reports, with daily and weekly routines.⁴ Grouping ads by tag shows you when many "variations" share the same concept.

Price: Starter is $999/mo for brands spending up to $50k a month on ads, with unlimited seats and ad accounts. Pro and Growth plans are priced on a call.

Limits: it works on ads that have already run, so it finds duplicates after you've paid for them. The price puts it out of reach for small accounts.

6. GetCrux: best for AI tagging and pre-flight testing at scale

What it does: GetCrux combines creative insights, AI tagging, competitor insights, ad inspiration and creative generation. Its Professional plan adds "Creative Pre-Flight Testing" along with automated workflows and a Slack integration.⁵

Price: Starter is $1,500/mo for up to $100k monthly ad spend and 2 ad accounts, with unlimited team members. Professional and Enterprise are custom-priced.

Limits: pre-flight testing sits on the custom-priced plan, and the entry price is the highest on this list.

How to choose

• You run your own store and spend a few thousand a month: start with the free Triple Whale audit to see your current mix, then check new versions in SellTheClick before you launch them.
• You're a media buyer whose new ads never get spend: use Meta's Creative test so each variant gets delivery, and check versions beforehand so you aren't testing the same idea twice.
• You run an agency or spend $50k+ a month: Motion or GetCrux for reporting on everything you've run, plus a pre-launch check for new batches.
• You mostly make video: add Alison.ai's free Preflight Plus to catch best-practice misses in each video.

A free check you can do before any tool

Put your versions side by side and answer four questions for each one. Is the hook different in the first line or first seconds? Is the angle different (problem, proof, offer, story)? Is the format different (static, video, carousel)? Is the person or persona different? If two versions answer "no" to all four, they're the same idea. Keep the stronger one and replace the other with something that changes at least one of those.

FAQ

Does Meta tell you if two ads are too similar?

We found no similarity score in Meta's help documentation. Meta's Creative test tells you which variant performed better once both have spend, not whether they were too alike to begin with.

What is the best free tool to check ad variations?

For live ads, Triple Whale's Creative Diversity Audit is free and needs no account. For giving variants a fair run, Meta's Creative test is free in Ads Manager. For a single video's best-practice score, Alison.ai's Preflight Plus is free.

Is the Meta "Entity ID" real?

Meta hasn't documented an Entity ID that groups similar ads. The idea comes from practitioners explaining why near-identical ads share delivery. Treat it as a useful model, not an official rule.

What counts as a different ad, not a variation?

A change to the hook, angle, format or persona. A new background colour, font or one-word headline change usually counts as the same idea.

Do these tools need access to my ad account?

SellTheClick, Triple Whale's audit and Alison.ai's Preflight Plus don't. Motion and GetCrux connect to your ad accounts to analyze what you've run.

How many variations should I test at once?

Fewer, more different ones beat many lookalikes. Meta's Creative test supports 2 to 7 variants per test, which is a sensible ceiling for most accounts.
