If you’re advertising on Facebook or Instagram, chances are you’ve relied on CTR (Click-Through Rate) and CPC (Cost Per Click) as your go-to metrics. After all, they’re right there in the dashboard—bold, immediate, and easy to compare.
But here’s the truth: clicks don’t always bring real revenue. Sales do. Leads do. Real engagement does.
CTR and CPC are only indicators of surface-level interaction. They tell you something’s happening, but not whether it’s meaningful, profitable, or sustainable. If you're serious about growing your business, you need to look beyond these vanity metrics and uncover what truly drives results.
So, how do you analyze performance beyond CTR and CPC? Let’s dive into the metrics that matter and what they reveal about your ads.
The metric that matters most: results
At the heart of every campaign lies a question: What action do I want users to take? This could be a purchase, a lead form submission, a webinar registration, or even an app install. Facebook calls this your “Result”, and tracking it alongside Cost Per Result (CPR) should be your primary focus.
The key here is aligning your campaign objective with the business outcome you care about. For example:
-
Selling products;
-
Running lead generation;
-
Building community.
Pro tip: set your campaign objective in Ads Manager to match the result you want. Facebook optimizes delivery based on this choice — pick wisely.
Consider this hypothetical: you're promoting a free strategy session. One campaign gets a high CTR but leads to only 5 bookings. Another gets half the clicks but 15 bookings. Campaign B is delivering better result, even if the top-level metrics suggest otherwise.

ROAS: Return on Ad Spend (with nuance)
ROAS (Return on Ad Spend) is one of the most powerful metrics for eCommerce and product-based businesses. It tells you how much revenue your ads are generating for every dollar spent. A ROAS of 4.0 means you earned $4 for every $1 invested — a great benchmark depending on your margins.
But ROAS isn’t always simple. It’s deeply influenced by your:
-
Attribution window (1-day click vs. 7-day click/view);
-
Average order value (AOV);
-
Sales cycle length;
-
Funnel structure (top vs. bottom).
Try this experiment: compare ROAS under multiple attribution settings. You might be underreporting revenue if customers take time to purchase.
Tip: pair ROAS with Customer Lifetime Value (CLTV) to understand whether a lower initial return is acceptable for long-term profit.

Landing Page View Rate: who actually went waited?
You got the click, now what?
Not everyone who clicks your ad lands on your site. Some hit the back button. Others bounce while the page loads. That’s why Landing Page Views (LPVs) matter so much more than clicks alone.
Use the Landing Page View Rate (LPVs divided by link clicks) to gauge technical performance and message consistency. A low rate may indicate:
-
Slow page load times;
-
A mismatch between ad promise and page content;
-
Poor mobile responsiveness.
Tip: use Facebook’s built-in Instant Experience to reduce load times or tools like Google PageSpeed Insights to identify bottlenecks.
From there, examine the Conversion Rate per LPV. If visitors land but don’t act, it’s not a traffic problem — it’s a page problem.
Ask yourself: Is my landing page experience strong enough to convert attention into action?
Engagement Quality: not all likes are equal
Too many advertisers lump all engagement together — likes, shares, saves, comments — as a single signal. But not all engagement carries the same weight.
For instance:
-
Likes are passive;
-
Comments indicate emotional or intellectual response;
-
Shares amplify your message to new audiences;
-
Saves suggest intent to revisit or purchase later.
If you're running a storytelling-based campaign or soft-sell video ad, high-quality engagement tells you that your message is resonating—even if immediate conversions are low.
Optimize by: prompting responses. Ask questions. Use poll stickers in Stories. Include a CTA like “Tag a friend who needs this”.
Consider this hypothetical: a fitness coach runs two ad videos. One garners 200 likes, the other 70 saves and 40 comments. The second ad, though technically “less popular”, has higher downstream value and community impact.
Frequency and ad fatigue: know when to switch
One silent killer of Facebook ad performance? Ad fatigue.
Frequency measures how many times, on average, a person has seen your ad. Once that number goes beyond 3, especially for cold audiences, performance often dips. People start ignoring your ad—or worse, hiding it, leading to negative feedback and increased CPMs.
Here are the key signs of ad fatigue:
-
CTR drops, CPC rises;
-
Engagement flatlines;
-
Relevance and quality rankings decline.
You can fix it by:
-
Swapping out creatives weekly (especially top-of-funnel);
-
Testing new copy hooks and value props;
-
Refreshing audience segments if reach is limited.
What to check in Ads Manager: look at Frequency, CPC trend lines, and Feedback Score weekly. Don't wait until your ROAS tanks.

Cost Per Result: your efficiency engine
While CPC tells you how much you pay for a click, Cost Per Result (CPR) tells you how much you’re paying for what you actually want.
This metric adjusts for different goals. For example:
-
Cost Per Lead (CPL);
-
Cost Per Purchase (CPP);
-
Cost Per App Install (CPI).
It’s a flexible but vital metric to measure efficiency across all funnel stages.
Here's a scenario: two campaigns promoting the same webinar.
-
Campaign A: $3 CPC, $25 CPL;
-
Campaign B: $6 CPC, $15 CPL.
Campaign B is the winner even if it looks worse on the surface.
Optimization tip: always set up conversion tracking properly. Without it, Facebook can't optimize delivery and you can’t measure CPR accurately.
Quality Ranking: how Facebook sees your Ad
Facebook scores your ad’s quality by comparing it to others competing for the same audience. The Quality Ranking metric is a hidden gem that affects your cost and reach—even when other metrics seem fine.
Poor rankings often result from:
-
Low engagement;
-
Negative feedback (hide/block/report);
-
Weak alignment between creative and audience expectations.
Monitor these three rankings:
-
Quality Ranking (ad vs. others);
-
Engagement Rate Ranking;
-
Conversion Rate Ranking.
Then do this to improve them:
-
Use more personalized creative;
-
Refine audience targeting;
-
Ensure your landing page matches your ad’s message.
Think of Facebook as a popularity contest. Ads that deliver value get rewarded with cheaper reach. Bland, annoying, or confusing ads get punished.
Final thoughts
CTR and CPC might be easy to track but they rarely tell you the full story.
If you're serious about driving real results, shift your attention to metrics that reflect value, not just activity. Measure:
-
What your audience does;
-
How much you’re paying per outcome;
-
How your content resonates;
-
What Facebook thinks of your ad.
By mastering these deeper signals — Conversions, ROAS, LPV, Engagement Quality, Frequency, Cost Per Result, and Quality Ranking — you’ll build campaigns that scale with confidence and consistency.
The question isn’t just “What’s working?” It’s “Why is it working and how can I double down?”
Start there. The rest will follow.
