What is Facebook Ad Relevance Score?

Ever pull up your Facebook Ads Manager and wonder why the old "Relevance Score" is missing? You're not alone. While that simple 1-to-10 metric is gone, the principle behind it is more important than ever. This article will break down what the relevance score was, what replaced it, and how to use the new, more powerful metrics to make your ads cheaper and more effective.

What Exactly Was the Facebook Ad Relevance Score?

For many years, the Facebook Ad Relevance Score was a key metric for advertisers. It was a simple score from 1 to 10 that estimated how well your ad was resonating with the specific audience it was being shown to. Think of it as a grade from Facebook on your ad’s performance.

A high score (like an 8, 9, or 10) suggested that your target audience found your ad interesting and engaging. Facebook rewarded this with a lower cost-per-click (CPC) and higher reach. Conversely, a low score (3 or below) indicated a disconnect between your ad and your audience. This often resulted in higher ad costs and reduced delivery, as Facebook's algorithm didn't see the value in showing an ad that people weren't responding to.

The score was calculated based on positive and negative feedback. Positive feedback included things like clicks, shares, likes, and video views. Negative feedback included people choosing to hide your ad or report it. In theory, it was a helpful at-a-glance indicator. In practice, it was a bit too simple.

Goodbye Relevance Score, Hello Ad Relevance Diagnostics

In 2019, Facebook officially retired the single Relevance Score in favor of a more detailed set of metrics called "Ad Relevance Diagnostics." It was a smart move. While a "score of 4" told you something was wrong, it didn’t tell you what was wrong.

Was the ad creative boring? Was the offer confusing? Was the landing page terrible? The old score couldn’t tell you. The new diagnostics were designed to give advertisers more specific, actionable feedback by breaking relevance down into three distinct components:

• Quality Ranking: How does your ad's perceived quality compare to ads competing for the same audience?
• Engagement Rate Ranking: How does your ad's expected engagement rate compare to ads competing for the same audience?
• Conversion Rate Ranking: How does your ad's expected conversion rate compare to ads competing for the same audience with the same goal?

Instead of a numeric score, each of these is ranked using one of five labels: "Above Average," "Average," "Below Average (Bottom 35% of ads)," "Below Average (Bottom 20% of ads)," or "Below Average (Bottom 10%)." This setup makes it much clearer where your ad is excelling and where it needs work.

Breaking Down the Ad Relevance Diagnostics

Let's take a closer look at what each of the three ranking metrics actually means and what influences them.

1. Quality Ranking

Quality Ranking focuses on the user's perception of your ad. It's not just about pretty pictures, it’s about a safe and positive user experience.

What it measures:

This metric is based on feedback from people viewing or hiding your ad, as well as characteristics Facebook associates with low-quality ads. This includes:

• Using clickbait or engagement bait ("Tag a friend who needs this!" can sometimes get flagged).
• Overusing sensationalized language or ALL CAPS.
• Leading to a poor landing page experience (e.g., slow load times, too many pop-ups, not mobile-friendly).
• Low-resolution images or videos.

A Below Average quality ranking is a serious signal that people are actively having a negative reaction to your advertisement or its destination.

2. Engagement Rate Ranking

This one is more straightforward and measures how well your ad captures attention and encourages interaction.

What it measures:

It compares the expected engagement rate of your ad with that of other ads targeting the same audience. Engagement includes all the classic interactions: clicks, likes, comments, shares, saves, and video views.

A Below Average engagement rate ranking suggests your ad creative isn't compelling. Maybe the visual is boring, the headline doesn’t hook the reader, or the copy doesn't speak to their interests. Your audience isn't outright rejecting it (like with low Quality Ranking), but they are scrolling right past it without a second thought.

3. Conversion Rate Ranking

This is arguably the most important of the three, as it directly relates to your campaign's ultimate goal.

What it measures:

It evaluates the expected conversion rate from users who clicked your ad. It compares your ad to others who have the same campaign objective (e.g., Purchases, Lead Generation, etc.) and are targeting the same audience.

A Below Average conversion rate ranking indicates that even if people click your ad, they aren't taking the desired action on your landing page. This points to a problem with your post-click experience. Common culprits include:

• A disconnect between the ad's promise and the landing page's offer.
• A confusing or high-friction checkout or lead-form process.
• An unconvincing offer or a weak call-to-action (CTA).
• Your audience targeting might be slightly off — you’re attracting clickers, not buyers.

How to See Your Ad Relevance Diagnostics

Finding these metrics in Ads Manager is quick and easy. Just add them as columns to your reporting view.

1. Navigate to your Facebook Ads Manager dashboard.
2. Select the Campaigns tab, then click on the ad set and ad you want to analyze.
3. In the main reporting table at the Ads level, look for the "Columns" dropdown menu (it's usually set to "Performance" by default).
4. Select "Customize Columns..." from the dropdown.
5. A new window will pop up. In the search bar on the right, type "Quality Ranking" and check the box next to it.
6. Repeat the process for "Engagement Rate Ranking" and "Conversion Rate Ranking."
7. Click the blue "Apply" button at the bottom right.

Your dashboard will now show these three columns for your ads. Note that these rankings will only appear after an ad has received about 500 impressions.

Using the Diagnostics to Improve Your Ads

Now for the most important part: using this information to make better ads. Here are some common scenarios and how to troubleshoot them.

Scenario 1: Everything is "Above Average" or "Average"

Diagnosis: Your ad is performing well! The audience, creative, and post-click experience are all aligned.

Action: Don't fix what isn't broken. Let the ad run and monitor its performance. Consider using this ad's creative and targeting strategy as a model for future campaigns.

Scenario 2: Low Quality Ranking

Diagnosis: Your audience is finding the ad itself annoying or the destination page frustrating.

Action: Check these things:

• Review Ad Policy: Is your ad toeing the line of any Facebook policies? Even if it was approved, it might be borderline.
• Rework Copy and Creative: Remove any sensationalized language, excessive emojis, or clickbait-style phrasing. Ensure your images are high-quality.
• Optimize Your Landing Page: Use Google's PageSpeed Insights to check your site's load time. Make sure it’s mobile-friendly and that the content delivers on the ad's promise immediately.

Scenario 3: Low Engagement Rate Ranking, High Conversion Rate Ranking

Diagnosis: A relatively small group of people are responding to your ad, but the ones who click are highly motivated to convert. This suggests your offer is great, but your creative isn't stopping the scroll.

Action: Test New Ad Creative:

• Try a completely different image or video. A static image could be replaced with a short video, or a graphic with a photo of a person.
• Rewrite your ad headline to be more attention-grabbing.
• Change your primary text. Ask a question to spark curiosity or lead with a compelling benefit.

Scenario 4: High Engagement Rate Ranking, Low Conversion Rate Ranking

Diagnosis: Your ad is popular and gets lots of comments and clicks, but those clicks aren't turning into sales or leads. This is a classic case of attracting the wrong crowd or having a broken post-click experience.

Action: Dig Into Audience and Offer:

• Refine Your Targeting: Is your audience too broad? Try narrowing it down with more specific Lookalike audiences or layered interests.
• Check Your Landing Page: Ensure your call-to-action is clear and prominent. Is the value proposition of your product or service immediately obvious?
• Strengthen Your Offer: Perhaps the offer itself isn't compelling enough to get people to convert. Could you offer free shipping, a discount code, or a free trial?

Scenario 5: Everything is "Below Average"

Diagnosis: There’s a fundamental disconnect between the three core pillars of a successful ad: Audience, Creative, and Offer.

Action: Go Back to the Drawing Board:

Don’t just tweak — rethink the entire ad. Start with your audience research. Did you truly understand their pain points and motivations? From there, brainstorm a new creative angle and a more compelling offer that is tailored directly to that audience. It is almost always better to pause the ad and start over with a fresh approach than to try and save an ad that is failing on every level.

Lower Costs are the Ultimate Goal

So, why should you spend time worrying about these three metrics? Because high relevance puts you in the driver's seat of the Facebook ad auction. When your ads are highly relevant, Facebook rewards you with:

• Lower Costs: You will pay less for impressions (lower CPM) and clicks (lower CPC) because the algorithm knows it is showing an ad that people want to see.
• Better Reach: The algorithm will prioritize showing your ads over less relevant ones, meaning you reach more of your target audience for the same budget.
• Higher Return on Ad Spend (ROAS): Lower ad costs combined with better conversion rates directly translates to a better bottom line for your business.

Final Thoughts

While the old numeric Relevance Score may be a thing of the past, the underlying concepts have only become more sophisticated. By understanding and diagnosing your ads with Quality, Engagement, and Conversion Rate Rankings, you gain specific, actionable insights that the old system could never provide. Use them not as a grade, but as a guidepost to systematically improve your campaigns.

Mastering these metrics often involves cross-referencing performance with other data and your own analytics. One of the biggest time-sinks for marketers is bouncing between a dozen different platforms to figure out what's really working. So many people have to log in to Facebook Ads, then Google Analytics, then their e-commerce platform just to connect campaign results with actual business impact. At Graphed , we solve this by connecting all your data sources in one place. We let you ask simple questions in plain English — like "Compare Facebook Ads spend vs. Shopify revenue by campaign for last month" — and instantly turn it into a real-time dashboard, so you can spend less time wrangling data and more time acting on it.
