What Is Ad Relevance Diagnostics?
Ad Relevance Diagnostics are Meta's three rankings. Quality, Engagement Rate, and Conversion Rate, showing how each of your ads compares against other ads competing for the same audience. They replaced the old 1 to 10 Relevance Score and give diagnostic-level clarity on why an ad is under-delivering.
How to read them
An ad shows Quality: Below Average (bottom 35%), Engagement: Average, Conversion: Above Average (top 35%). Translation: the auction is punishing the creative (low quality) but downstream conversion is fine. Fix: refresh the creative, the offer/LP is working, the ad itself is not.
Benchmarks
- Rankings only appear after 500+ impressions.
- Any ranking of 'Below Average, bottom 10%' should be paused or rebuilt.
- 'Average' is the middle 35%. 'Above Average' is the top 55%.
Why it matters
The three rankings tell you exactly where to fix. Low Quality → new creative. Low Engagement → weak hook or wrong audience. Low Conversion → landing page or offer issue. Without this breakdown you'd waste time changing the wrong lever.
Common mistakes
- 1.Ignoring diagnostics because they're 'just a score.' They correlate strongly with delivery cost.
- 2.Judging with < 500 impressions, rankings haven't stabilised.
- 3.Boosting posts and expecting rankings, some placements/formats don't produce them.

FAQs about Ad Relevance Diagnostics
How do I improve my Quality ranking?
New creative with a stronger hook, more native-feeling format, better resolution. Avoid clickbait, sensationalism, or 'engagement bait' phrases Meta penalises.
Do rankings affect delivery cost?
Yes. Below-average ads pay more per impression in the same auction. Above-average ads pay less. The gap can be 20 to 50%.
Where do I find the diagnostics?
Ads Manager → columns → customize columns → check Quality, Engagement, and Conversion rankings. They apply per ad, not per ad set.
