Facebook ad metrics

With all the Facebook ad metrics available, it's hard to know which to focus on. Learn the top 6 most important metrics (and the 3 you can forget) in this guide.

There are about as many Facebook ad metrics as there are stars in the sky—which makes knowing which metrics are actually important incredibly difficult (especially for beginners).

In this article, we'll break down the top 6 metrics that are important for your ads and why they're important, as well as list the main 3 metrics you can forget about entirely.

Let's get started!

How to track your metrics in Facebook Ads Manager

Before we dive into which metrics you should track and why, it's a good idea to first look at how to analyze your Facebook ad campaign data. And a good place to see that data will be inside the campaign view of Ads Manager.

When you first log in, Facebook will have a pre-defined list of performance metrics in its default view.

Facebook ad metrics - Facebook Ad Manager

This default view will contain information about delivery, bid strategy, budget, results, reach, impressions, CPA, amount spent, end date, frequency, and unique clicks.

All in all, most of these are useful and will be listed in our top metrics to track below—however, some will also be on the unimportant list (more on that in a second).

Facebook does provide us with some other pre-made metrics if we're looking for more specific information.

To access these, simply click on the 'columns' link underneath the ads tab.

Columns - Facebook ad metrics in ad manager

Here you'll see a list of different Facebook ad metric breakdowns that focus on specific points of information. Those interested in engagement, for example, would find the Engagement view useful as it contains information on your post likes, comments, saves, shares, and page likes.

If that isn't enough for you (or you don't see what you need), you can also customize a specific view to fit your needs by clicking Customize Columns at the end of the list.

Customize columns - Facebook ad metrics

As you can see, you can find any metric known to man (and Zuckerberg) here. If you want a specific breakdown of each conversion event, for example, this would be the place to find it.

There's even a way to add your own custom metric to your reporting as well:

Custom Facebook ad metrics

In the example above, I've created a formula to give us a breakdown of revenue by unique clicks.

You can also break down all this information further if needed. Under the 'breakdown tab', you'll see the list of additional options to view your results with:

Facebook ad metric breakdowns

By Time. View your results by day, week, 2 weeks, or month.

By Delivery. You can focus on a different subset of campaign data by using delivery to break down the data by things like age, gender, time of day, country, platform, and placement.

By Action. Here, you can break down the different types of actions a bit more in detail. You can view things like what type of post reactions you received (Like, Haha, Wow, etc.), whether your video was played with the sound on or off, or a breakdown of each card in your carousel.

The clear winner here for usefulness is the Delivery section, in my opinion. This is useful for things like:

  • Viewing your results by platform and device type to see if your audience has higher engagement with certain devices or placements (Instagram, etc.).
  • Checking to see if video, static images, or carousels performed better with media type
  • Breaking down performance in geographic areas if using a wide location target audience

Feel free to experiment with both the metrics you view and the available breakdowns to get clearer insights into your ad performance.

Now that we've learned where to view your results, it's time for the star of the show: which Facebook ad metrics matter and which don't.

3 Facebook ad metrics that only distract you

You may think you need to have the highest score in every possible metric to be successful with Facebook ads - but you couldn't be further from the truth. There are several metrics that are not as important as Facebook makes them out to be.

I, for one, love to rant endlessly about Facebook ads, so let's start off with one I hate the most.

Estimated ad recall lift

For most advertisers, this metric might be something you've never heard of (and for good reason, in my opinion). However, you may have seen a poll on your Facebook newsfeed asking if you remember seeing a brand's ad:

estimated ad recall lift

This poll is part of the estimated ad recall lift metric.

In short, the estimated ad recall lift is calculated as 'the difference between the predicted recall of people who saw your ads and the number of people who didn't see your ads'. You'd see this metric when using a video in a campaign or using the Brand Awareness objective.

Facebook gathers the results for this metric by asking users to fill out polls like in the example above and combining it with 'machine learning data' for an end result. They don't explain what components the said machine learning takes into consideration.

If it sounds sort of convoluted and confusing to you, you're not alone. Facebook's own documentation even states that this metric isn't as clear cut as others:

Estimated ad recall lift is labeled as an ‘estimated’ and ‘in development’ metric. This means that we are continuously improving our calculation methodology, and, as a result, we recommend that you should only compare this metric across campaigns running simultaneously.
Facebook's ad recall lift documentation

Given that information, we have to put this data point in the ignore pile. While having a memorable ad is a good sign that your campaign will perform well, it's best to take this metric with a grain of salt.

If you see your ad has a great click-through rate, your conversions are high, and your CPA is where you want it to be, there's absolutely no reason to change your campaign to improve this metric.


Next up is impressions. Facebook defines impressions as the number of times your ad was seen in total by everyone in your audience. Keep in mind one person can have multiple impressions (views) of your ads, so it's not reflective of how many people have seen your ad, just the total number of views.

Some of you might gasp because impressions didn't make the 'important' cut, but there's a solid reason behind it: As long as our ad is delivering (and you see your impressions go up), you don't need to worry too much about it.

While it's important that your ads are being delivered and seen, there's no set number of impressions your ad needs to meet in order to be successful. We also shouldn't consider it a 'north star' metric or one to solely base our judgment of performance on.

That being said, when you're debugging your campaign performance, if you noticed few impressions on your campaign overall, it could be a sign something is misaligned within your budget/bid that's preventing you from winning the ad auctions and having your ads delivered.

Should you monitor impressions? Of course. But it shouldn't be considered one of the top metrics to judge your campaign performance.

Ad Relevance Diagnostics

Previously, Facebook used a metric called the Relevance Score to determine how relevant your ad was to the audience you were targeting on a 1-10 scale. In order to make this a bit more actionable, Facebook replaced this metric with an entirely new system called ad relevance diagnostics.

While the goal is overall the same, this new system allows you to view the quality of your ad, engagements, and conversions.

Unfortunately, the new system they created is more complex than a 1-10 scale and has a swathe of different outcomes and troubleshooting tips depending on which part of the score you're struggling with:

Facebook ad relevance diagnostics

While it's true that having a good-quality ad typically results in better conversions and performance, it's actually not necessary to have the highest scores across these specific categories to meet your own advertising objectives.

Ironically, you may see your ads performing very well while having low scores in any of these areas.

To drive the point home, Facebook specifically mentions that this metric should only be looked at to diagnose underperforming campaigns and not successful ones:

High relevance is correlated with high performance, but it's not always the reason for high performance. As such, use ad relevance diagnostics to diagnose underperforming ads – not to optimize ads that are already meeting your advertising objectives. Achieving high ad-relevance diagnostics rankings should not be your primary goal and doesn’t guarantee an increase in results.
Facebook's ad relevance documentation

Like impressions, if your campaign is achieving a significant amount of conversions, meeting your ideal cost, and generating clicks, it's better not to lose sleep over low scores in any of the three categories.

The top 6 crucial Facebook ad metrics you must track

After sifting the duds from the winners, let's dive into the most important metrics you need to track to be successful with your Facebook ads.

Cost per result

Cost per result (CPR) is the average cost per action (CPA) you want from your campaign and is related to your campaign setup. For lead generation campaigns, your cost per result would refer to your cost per lead. For video views, cost per video view.

It's calculated as the amount of money you've spent divided by the total number of results.

Cost per Result formula

Why it's important:

After all is said and done, your team will likely want to know two things - the number of results you had and how much it cost to achieve them.

Your CPA will also give you critical information like:

  • Which audience or creatives are giving you the most results for the cheapest price
  • Which elements of your campaign you should remove from your focus
  • Where opportunity exists within your audience targeting

Given that the cost of advertising can outweigh your return if you're not careful, ensuring you're meeting your goals within budget is critical for your success.

Cost per result benchmarks

It’s difficult to know what sort of costs to expect, especially if you’re just starting out. Luckily Madgicx sees around $9.6B in ad spend pass through our system every year, so we have some benchmarking data available to help you budget accordingly.

While there are a lot of available goals to cover, we’ll focus on the most popular ones in this article. The first of which is the cost per lead.

The cost per lead fluctuates drastically during the year and has some of the biggest peaks and valleys of any chart in this post. We see highs of around $153.48 for leads during peak advertising seasons and around $51.16 after that season ends.

We broke this data up into quarters for a view of how the year performs overall:

Facebook ad cost per lead quarterly bar graph

Q4 (and Black Friday/Cyber Monday in particular) are jam-packed with ads from eCommerce advertisers pushing their holiday campaigns. The more traffic Facebook has, the more expensive this option becomes.

The average for this figure across the timespan above is $81.

Cost per purchase is next up to bat. Here, we don’t see as drastic of a change as in the previous graph, but we still see a significant change in highs and lows.

Here, we were able to see highs of around $64.01 per purchase and lows of $29.94. 

Facebook ad cost per purchase quarterly bar graph

The average for the time span above is $46.55.

Cost per conversion

While CPA looks at the main goal of your campaign, you can actually track the cost of other conversions that may be happening within your campaign.

For example, a traditional eCommerce ad would likely fire off the following conversion events as the user progresses through checkout:

  • View page
  • Add to cart
  • Add payment information
  • Purchase

Cost per result would refer to the purchase event, which is, of course, the most important goal for us. But looking at the cost per conversion for the other events in this campaign can be very useful for determining where we could improve our efforts.

Your cost per conversion is calculated as the amount spent divided by the number of conversions.

Cost per Conversion formula

Why it's important:

If you see your cost per conversion along your entire funnel is high, it's likely the audience you're targeting isn't suited for what you're trying to sell. Likewise, cost-per-conversion issues across your ads can mean that your creative and your ad copy need more work.

Cost per conversion benchmarks

Just like for the CPR metrics, there are a ton of conversions you can track with your Facebook ads. Let’s focus on cost per add-to-cart and cost per landing page view.

The cost per add-to-cart saw highs of around $11 and lows of $3.80.

Facebook cost per add to cart quarterly bar graph

The average cost of add-to-cart actions across the timespan above was $7.55.

The next item here is the cost per landing page view. This data set saw highs of $1.83 and lows of $1.05, with a little fluctuation in between. 

Facebook cost per landing page view quarterly bar graph

The average cost of landing page views across the timespan above was $1.50.

Conversion rate

You probably get it by now—conversions are important. It shouldn't be surprising then to see the conversion rate in this list.

Conversion rate is calculated as the number of people who clicked on your ad and then took your desired action, displayed as a percentage.

conversion rate formula

Why it's important:

Since the goal of your campaigns is to get as many results as you can, the conversion rate is extremely important in determining how successful you are at getting your audience to take that action.

Monitoring the conversion rate can help:

  • Provide you information on your ability to convert your overall traffic for your audience segments
  • Determine benchmarks on how much traffic you need to achieve x result
  • Show you where along your funnel dropoff occurs so you optimize that portion further

Overall, cost per result/conversions, as well as your conversion rate, should be your 3 main staples when trying to determine what is going right (or wrong).

Return on ad spend (ROAS)

On theme with our conversion obsession is also our cost obsession—and no other metric more clearly states this than the return on ad spend or ROAS.

Return on ad spend is different from the cost per result in that it tells us how much money we made vs. the cost that we incurred to generate that revenue. It's calculated as the website purchase value divided by the total amount spent.

ROAS formula

For example, if we have achieved $20k in revenue from a campaign and only spent $5k, our ROAS is 4. This means for every $1 we spent, we actually made $4.

Why it's important:

The reason why this metric is important is that it gives us a direct figure for how much return we see on our ads and is one of the clearest ways you can determine if your campaign was a true success by revenue standards.

Just like with the cost per result/conversions, ROAS is great for determining which campaigns generated the best results - in this case, the most revenue per dollar spent.

ROAS benchmarks

ROAS here didn’t fluctuate as much as some of the other data sets on this list and kept fairly consistent across the time frames. We saw highs of 2.03 and highs of 1.88.

The average ROAS across the time span above was 2.

Outbound click-through rate (Outbound CTR)

No true list of Facebook ad metrics is complete without looking at the click-through rate. However, we want to take a look at outbound click-through rates in particular. 

The normal click-through rate calculates clicks on your ad regardless of whether they are on or off Facebook’s site. That means someone who has clicked on your ad and gone to your Facebook business page would be counted in this figure.

Outbound clicks, however, are only counted when a user is leaving Facebook (to visit your website, for example). For those with a traffic goal, tracking outbound CTR would be a more specific and insightful data point.

Outbound CTR measures the number of people who have clicked on your ads and have left Facebook, divided by the number of times your ad was seen, expressed as a percentage.

Outbound CTR formula

Why it's important:

Outbound click-through rate makes the list of top performance metrics for one major reason - it's the best way to determine if the creative you're serving to your audience is actually interesting to them at all.

The click-through rate is useful for:

  • Determining which ad creative is most appealing to your target audience
  • Seeing if your audience targeting is actually aligned with the product or service you're offering

If you have a low CTR, chances are either your ad copy needs to be reworked to relate the value of what you're offering, or your audience needs to be narrowed to those who would benefit most from your solutions.

Outbound click-through rate benchmarks

For outbound CTR, we found benchmarks that ranged from .99% at the most to .61% at the lowest.

Facebook ad outbound CTR quarterly bar graph

All in all, the average outbound CTR, factoring in all of the percentages above, is .79%.

Engagement rate

Last (but certainly not least) in this article is the engagement rate. The engagement rate refers to the number of people who are engaging with your ad (likes, clicks, shares, comments, etc.), expressed as a percentage.

Engagement Rate formula

Why it's important:

Along with click-through rate, engagement rate is another great way to determine if your audience is actually interested in your ad campaigns. While the click-through rate solely focuses on clicks, the engagement rate also factors in social proof as well.

While it's good to track clicks separately, engagement on your ads is also important, as the more positive social proof an ad has, the more users are likely to try out your brand for the first time, and it can also increase your overall reach.
