How to Set Up and Actually Use Meta’s Audience Segments Reporting

ROAS is great. Conversion value? We love her. But if you want to really understand what's happening in your account, who's buying, and where you're wasting money or need to adjust, you need to be looking at Meta's Audience Segments Reporting.

This little-known breakdown gives you the kind of insight that can help you refine your creative, spot funnel leaks, and fix problems before your cost per purchase starts creeping up. And the best part? You probably already have access to it, you just haven't clicked the right button yet.

Let's fix that.

What Is Audience Segments Reporting?

Meta's Audience Segments Reporting is a breakdown tool inside Ads Manager. It shows you how different types of people interact with your ads, even if you're running broad targeting.

You'll see your stats broken down by:

• New customers

• Existing customers

• Engaged audience

Meta automatically categorises users based on their past interaction with your business, not just how you targeted them. That means you can learn a lot about who your ads are resonating with, and who's not quite there yet.

How To Set It Up (It's Easier Than You Think)

Before you can use this reporting properly, you need to make sure Meta has enough information to work with. Head to your Audience Segments section in Ads Manager. If you manage multiple accounts, make sure you have the right account selected in the top right hand corner.

Expand Engaged Audience and click the little arrow until it opens up. Here you'll select your existing custom audiences for your warm audience, think social engagement, website visits, email lists, and anything that indicates they've had an interaction with your business.

Then expand Existing Customers. Make sure you only add customers here, this is not the place for your mailing list. Add 180-day purchases from your pixel data, or upload a CSV of all your past customers if you prefer. Then hit confirm.

How To Access The Data

• Go to Ads Manager

• In the top menu, click Breakdown

• Choose By Delivery

• Select Audience Segments

That's it. You'll now see your ad performance split out by customer type.

What You Can Learn (and Why It Matters)

Here's where it gets juicy. You might discover:

• Most of your conversions are coming from existing or returning customers (great for loyalty, not so great for growth). If most of your budget is going toward people who would've bought anyway, that's going to affect your Marketing Efficiency Ratio and just cost you more in the long run

• New customers are clicking but not converting (your landing page might need work, or your messaging isn't strong enough for cold leads)

• Engaged audiences are watching your videos but not clicking (hook is good, CTA is weak)

This breakdown becomes especially important when you're running Advantage+ campaigns. Because you're handing over so much control to Meta, you need to monitor where your budget is actually going. You might think you're bringing in new customers, but if the majority of your spend is being absorbed by existing ones, you're not really growing, you're just preaching to the choir.

Ideally you'll see:

• New customers getting the majority of your budget

• Engaged audiences receiving the next largest share

• Existing customers getting the smallest slice

If it's the other way around, you're not building your funnel. You're inflating your results in the short term and heading for a ceiling.

You can use these insights to:

• Refine your creative

• Improve your offers

• Adjust your funnel strategy

• Spot creative fatigue before performance tanks

• Check your spend allocation and rebalance if needed

This is also particularly helpful for making sure your creative is covering all stages of the funnel, even if you're not actively running a structured funnel. You might not have campaigns split into TOF, MOF, and BOF, but you still need creative that speaks to each level of awareness. Audience segment reporting helps you spot those gaps.

Real World Example

We had a client who thought their TOF ads were working beautifully. Great ROAS, lots of conversions, but after digging into audience segments, we saw that nearly all purchases were coming from returning customers. Their TOF was essentially acting as a BOF.

We added exclusions, changed up the creative, and started getting new customers on board.

Audience Segments Reporting isn't flashy. It doesn't come with fireworks or a shiny dashboard, it's even hidden in the depths of the breakdown feature. But it tells you what you actually need to know: who is seeing your ads, what stage of the funnel they're in, and whether your content is working for them.

If you're not using it yet, now's the time to start. Your creative will thank you. Your budget will thank you. And your bank account definitely will too.
