You’re doing everything the checklist says. Statics, video, UGC, carousels, all four running inside the same ad set. By any reasonable definition, that’s a diverse creative mix.
Ads Manager disagrees. Open the new Creative Diversity Score sitting quietly in your reporting, and there’s a real chance it still reads Low, even with all four formats live.
This isn’t a bug, and it isn’t you doing something wrong in the obvious sense. It’s a sign that the Creative Diversity Score isn’t measuring what most advertisers assume it’s measuring. Understanding the actual mechanic behind it matters, because this score is showing up next to your CPA in reporting, and a Low rating sitting beside decent performance numbers is confusing enough that it’s worth getting straight.
What the Creative Diversity Score Actually Is
Ads Manager now rates each ad set’s creative diversity as Low, Medium, or High. On the surface, it reads like a simple checklist, run more format types, get a better score. That’s the assumption most advertisers bring to it, and it’s the assumption that’s producing all the confused Low ratings on accounts that look genuinely diverse to a human eye.
Format variety alone doesn’t appear to be enough to move the Creative Diversity Score. Accounts running statics, video, UGC, and carousels together, a mix that covers essentially every major format type available, have still logged Low ratings. That gap between what looks diverse and what scores as diverse is the actual story here.
Meta hasn’t published detailed documentation breaking down exactly what the Creative Diversity Score weighs beyond format count, which means the honest answer right now is that the scoring logic isn’t fully transparent. What’s observable is the outcome: format count alone isn’t the primary input, or a four-format account wouldn’t be reading Low.
The Likely Explanation, and Why It's Not Confirmed
The most plausible read, based on how Andromeda and Meta’s broader creative systems have behaved elsewhere this year, is that the score is measuring variation within each format, not just the presence of multiple formats. Four different formats all built around the same hook, the same message, and the same visual structure may register as low diversity to a system that’s actually evaluating creative signal variety, not format labels.
This tracks with Meta’s broader 2026 direction. Creative volume and specificity have been weighted more heavily in delivery, and the platform has increasingly framed creative itself as a form of targeting signal rather than a static asset sitting next to targeting. A diversity score built on that same logic would care more about how differently your creative performs and looks across variations than about which format buckets you’ve technically checked off.
This explanation isn’t confirmed by Meta directly, so treat it as the most likely mechanic rather than settled fact. What is confirmed, from direct observation across multiple accounts, is that format count by itself doesn’t reliably move the score
Why This Score Matters Even Without Full Documentation
Ignoring an unclear metric is tempting, especially one without a public methodology. That’s a mistake here, because the Creative Diversity Score isn’t just sitting in a corner of your reporting for reference. It’s showing up directly next to your CPA, which strongly suggests Meta intends advertisers to read the two together, and likely intends the score to eventually correlate with delivery or optimization behavior, even if that connection isn’t explicit yet.
Waiting for full documentation before acting also risks missing an early signal. If the Creative Diversity Score is an early indicator of how Andromeda is actually evaluating your creative set, accounts that improve it now may be building a head start on whatever this metric eventually gets tied to, whether that’s more explicit or not.
How to Actually Raise a Low Creative Diversity Score
Stop treating format count as the lever. If you’re already running four formats and still reading Low, adding a fifth format is unlikely to move the needle, since format presence doesn’t appear to be the primary driver.
Focus instead on varying the actual creative substance within each format. Different hooks, different opening frames, different pacing, different visual structure across your video assets, rather than four videos that are essentially the same script reformatted. The same logic applies across statics, UGC, and carousels, real variation in message and structure, not just variation in file type.
Audit your current top-spending ad set specifically. If every asset in it opens with a similar hook or follows a near-identical structure despite different formats, that’s the most likely reason the score reads Low, and it’s the most direct thing to fix first.
Track the Creative Diversity Score next to CPA over several weeks as you make these changes, rather than expecting an immediate shift. Since the underlying methodology isn’t fully public, the safest approach is treating this as a directional signal to test against your own account’s real performance, not a rule to chase blindly.
Common Mistakes to Avoid
Assuming more formats automatically means a higher Creative Diversity Score is the core misunderstanding driving most of the confusion around this metric right now.
Ignoring the score because Meta hasn’t published full documentation risks missing an early signal tied to how Andromeda evaluates creative, especially given the score’s placement directly next to CPA in reporting.
Chasing a High rating for its own sake, without checking whether changes actually move your real performance numbers, treats an unexplained metric as a goal rather than a diagnostic tool. Until the methodology is clearer, performance should still be the primary measure of success.
Conclusion
A Low Creative Diversity Score on an account running four different ad formats isn’t a contradiction, it’s a sign that format variety and creative variety aren’t the same thing to Meta’s system. The most likely explanation is that the score is measuring real variation in hook, message, and structure within each format, not simply how many format types are present.
The practical move today is straightforward. Pull up your current ad sets, check whether your different formats are actually saying and showing different things or just repackaging the same creative idea, and treat the Creative Diversity Score as one more signal to test against your own CPA rather than a checklist to satisfy blindly.
FAQs
1. Why does my Creative Diversity Score read Low even with multiple ad formats running?
Format count alone doesn’t appear to be the primary factor. The score likely measures real variation in hook, message, and structure within each format, not just how many format types are present.
2. Has Meta published official documentation on how the Creative Diversity Score is calculated?
Not in full detail as of this writing. The scoring logic isn’t fully transparent, so current understanding is based on observed patterns rather than confirmed Meta documentation.
3. Does the Creative Diversity Score directly affect delivery or CPA?
This isn’t officially confirmed, but the score appears directly next to CPA in reporting, which suggests Meta intends the two to be read together, and possibly correlated over time.
4. What’s the fastest way to improve a Low Creative Diversity Score?
Focus on varying the actual creative substance, different hooks, structures, and messaging, within your existing formats rather than simply adding more format types to your ad set.
