Why Change Your Facebook Ad Audience?

Before jumping into the "how," it's helpful to understand the "why." Tweaking your audience isn't just about random trial and error, it's a strategic move to improve your campaign's performance. Here are a few common reasons you might need to make a change:

• Poor Performance: The most obvious reason. If you're seeing a high cost-per-click (CPC), low click-through rate (CTR), or a disappointing return on ad spend (ROAS), your audience might not be the right fit for your offer.
• Ad Fatigue: If you show the same ads to the same people for too long, they'll start to ignore them. You can spot this by watching your ad's Frequency metric. If it gets too high and performance dips, it's time to find a fresh audience.
• New Customer Insights: Maybe you've discovered that a different demographic engages more with your brand or that users with a specific interest are your most profitable customers. You’ll want to apply these new insights to your ad targeting.
• Testing and Scaling: To grow your business, you need to find new customer segments. Changing or adding audiences, like testing a Lookalike Audience against an interest-based one, is the primary way to find new pockets of customers and scale your campaigns.

First, Understand Facebook's Campaign Structure

To change your audience, you first need to know where audience settings live within Facebook's system. Wasting time clicking through campaigns and ads is a common frustration, but it's easily avoided once you understand the simple hierarchy:

Campaign > Ad Set > Ad

Here’s a simple breakdown:

• Campaign: This is the highest level, where you set your main advertising objective, like getting more website traffic, generating leads, or driving sales.
• Ad Set: This is the crucial part for our task. The ad set is where you define who you want to target. All of your audience settings - location, age, gender, interests, custom audiences - are controlled at the ad set level. You also set your budget and schedule here.
• Ad: This is the specific creative your audience will see - the image, video, headline, and copy. You can have multiple ads within a single ad set.

Think of it like this: your Campaign is the overall goal (e.g., "Sell more products this month"). The Ad Set is the specific group of people you're trying to sell to (e.g., "Women aged 25-40 in California who are interested in yoga"). The Ad is the actual advertisement they see. Therefore, to change your audience, you will always make edits at the Ad Set level.

How to Edit the Audience for an Existing Ad Set

If you've identified an underperforming audience in a live ad set and want to change it directly, the process is straightforward. This is a good option for making small corrections. Be aware, however, that editing a live ad set will push it back into Facebook's "learning phase", which can temporarily affect performance as the algorithm recalibrates.

Here’s how to do it step-by-step:

Step 1: Navigate to the Ads Manager

Log in to your Facebook Business account and go to the Ads Manager. You’ll see a dashboard with a list of your campaigns.

Step 2: Select Your Campaign and Ad Set

Find the campaign containing the ad set you want to modify. You can either click on the campaign name to see its ad sets or click the "Ad Sets" tab in the navigation menu on the left.

Step 3: Open the Editing Panel

Hover over the name of the ad set you wish to change and click the "Edit" link that appears just below its name. This will open a side panel where you can modify all of the ad set's settings.

Step 4: Go to the "Audience" Section

In the editing panel, scroll down until you see the "Audience" section. This is where you can change every aspect of your targeting.

Step 5: Modify Your Targeting Details

Here you can make your desired changes. This could include:

• Custom Audiences: Add or remove custom audiences (like website visitors or email lists) or Lookalike audiences.
• Location: Change a country, state, city, or even drop a pin with a radius for local businesses.
• Age & Gender: Adjust the age range or gender you're targeting.
• Detailed Targeting: This is where you change interests, behaviors, or demographics. You can add new ones or remove those that aren't performing. You can also add exclusion criteria here to narrow your audience.

Step 6: Publish Your Changes

Once you are happy with your new audience configuration, click the green "Publish" button at the bottom right of the screen. Your changes will be reviewed and, once approved, your ad set will begin delivering to the new audience after it goes through the learning phase again.

The Pro Method: Duplicating an Ad Set to Test a New Audience

Editing a live ad set is fast, but it has a downside: you lose the performance data and optimization progress of the original audience. A more strategic and common practice among experienced advertisers is to duplicate the ad set and change the audience in the copy. This lets you run an A/B test to see which audience performs better without disrupting what’s already working.

This is the best method if you're trying to discover new profitable segments or want to test a hypothesis without risking your current results.

Here’s how to do it:

Step 1: Go to Your Ad Sets Tab

Navigate to the Ads Manager and find the ad set you want to use as your baseline. This is usually your best-performing ad set or the one you want to improve upon.

Step 2: Duplicate the Ad Set

Select the ad set by clicking the checkbox next to its name. In the toolbar that appears above, click the "Duplicate" button.

Step 3: Rename Your New Ad Set

A new ad set draft will be created, often with " - Copy" in the title. Immediately rename it to something that describes your new audience (e.g., "Lookalike Audience - 1% US Purchases" or "Interests - Yoga + Lululemon"). This keeps your account organized and makes performance analysis much easier later on.

Step 4: Change the Audience in the New Ad Set

Just like in the editing method, scroll down to the "Audience" section of your newly duplicated ad set. Now, modify the targeting to what you want to test. Change the interests, swap in a Lookalike Audience, or adjust the demographics. The key here is to only change the audience variables so you can accurately compare its performance against the original.

Step 5: Review and Publish

Ensure that the budget and other settings are what you want them to be, then click "Publish." Your new ad set will go into review, and once approved, it will start running alongside your original ad set. You can then monitor the performance of both to declare a winner.

Best Practices to Keep in Mind

Whether you edit or duplicate, following a few simple rules will help you get more reliable results and avoid common mistakes.

• Change One Thing at a Time: If you change the age range, location, and all the interests at once, you won't know which change was responsible for the performance boost (or drop). If you're testing, be scientific. Test Lookalikes vs. Interests first. Then test different types of interests against each other.
• Mind the Audience Overlap: If you run several ad sets at once, you might have them targeting similar groups of people. This causes your own ad sets to compete against each other, driving up your costs. Use audience exclusions to prevent this. For example, if you're targeting a Lookalike Audience, you might want to exclude your recent website visitors, who you’re targeting in a separate retargeting campaign.
• Give it Time: Don't make a decision after just one day. Every time you make a significant edit or launch a new ad set, it needs time to exit the learning phase and collect enough data for you to make an informed judgment. Let it run for at least 3-5 days before deciding if the new audience is a success or failure.

Final Thoughts

Changing the audience on your Facebook ads is a fundamental skill for any marketer. By understanding how to do it at the ad set level, you can quickly pivot when performance stalls. More importantly, using the duplication method allows you to test systematically, which is the key to unlocking new customer segments and scaling your business sustainably.

Knowing which audiences to test often comes from understanding the full picture of your marketing and sales data. Often, marketers are stuck looking at Facebook Ads Manager, but the real story is in how those ads translate to actual sales on Shopify or leads in Salesforce.
