How to Create Remarketing Audience in Google Analytics

Ever notice how an ad for a pair of sneakers you checked out an hour ago quietly follows you to the next website you visit? That’s remarketing, and it's one of the most effective ways to get your brand back in front of people who are already familiar with you. Google Analytics gives you the tools to create these powerful audiences directly from your own website data. This article will walk you through exactly how to set up remarketing audiences in GA4, step-by-step, with practical examples you can use right away.

What Exactly Is a Remarketing Audience?

A remarketing audience, sometimes called a retargeting audience, is simply a list of users who have previously visited your website or used your app. Instead of showing ads to a broad, cold audience, remarketing allows you to focus your ad budget on a "warm" audience - people who have already demonstrated interest in your products or services.

Why is this so powerful? You’re no longer a stranger. These users know your brand, so you don't need to start your sales pitch from scratch. Your goal is simply to remind them of what they were interested in and give them a nudge to come back and complete an action, whether that's making a purchase, signing up for a newsletter, or downloading a resource.

Before You Begin: Required Setup

Before you can start building audiences, there are a few prerequisites you need to have in place. It only takes a few minutes to check these settings, and it will save you a headache later on.

1. Link Your Google Analytics and Google Ads Accounts

This is the most critical step. Your audiences are built in Google Analytics, but they are used in Google Ads. Linking the two platforms allows GA4 to share your newly created audiences with your ad account automatically.

How to check if they're linked:

• In Google Analytics, go to Admin (the gear icon in the bottom left).
• Under the Property column, look for Product Links and click on Google Ads Links.
• If you see your Google Ads account listed, you’re good to go. If not, click the blue "Link" button and follow the prompts to connect the correct account. You'll need admin access to both platforms to do this.

2. Activate Google Signals

Google Signals is a GA4 feature that collects additional anonymized data from users who have turned on "Ads Personalization" in their Google accounts. Activating it enables cross-device tracking, meaning if someone browses your site on their phone and later on their desktop, Google can recognize them as the same user.

This is incredibly important for remarketing because it gives you a more accurate user count and allows you to reach them with ads regardless of which device they’re currently using.

How to activate Google Signals:

• In GA4, navigate to Admin > Data Settings > Data Collection.
• You'll see a toggle for Enable Google signals data collection. Make sure it's turned on. You’ll also need to acknowledge the user data policies.

3. Check Your Permissions

To create or edit audiences in Google Analytics, you need to have the Editor role (or higher) for the GA4 property. If you can access the Admin section and see the "Audiences" option, you likely have the permissions you need.

A Step-by-Step Guide to Creating Your First Remarketing Audience in GA4

Once your accounts are linked and Google Signals is active, you’re ready to build your first audience. Let's walk through the process of creating a classic "cart abandoner" audience.

1. Navigate to the Audience Builder: In GA4, go to Admin > Audiences. If this is your first time, you may see some default audiences like "All users" and "Purchasers," but we want to build our own. Click the blue "New audience" button.
2. Choose to Create a Custom Audience: You’ll be presented with a few options. GA4 offers some helpful "Suggested audiences," but for maximum control, we'll start from scratch. Click on "Create a custom audience."
3. Name Your Audience: This might seem trivial, but name it something clear and descriptive. You will see this name in your Google Ads account, so "Cart Abandoners - Last 30 Days" is much more helpful than "Audience 1."
4. Define the Audience Conditions: This is where the magic happens. You’re going to tell GA4 the exact criteria a user must meet to be included in this audience.
5. Set the Membership Duration: On the right side, you'll see "Membership duration." This determines how long a user stays in your audience after they last meet the criteria. For cart abandoners, 30 days is a common choice. A high-ticket item might warrant a longer duration, like 60 or 90 days. Keep it on "Set a limit" and enter your desired duration.
6. Save Your Audience: Once everything is configured, click "Save" in the top right. Your audience will start populating with users who meet the criteria. Note that it can take 24-48 hours for a new audience to be fully available and populated within Google Ads.

5 Effective Remarketing Audiences You Can Build Today

Now that you know the mechanics, let’s explore some other high-value audiences you can create to reconnect with different types of visitors.

1. Visitors Who Landed on a Specific Page

This is useful for remarketing based on interest in a specific product, service, or feature.

• Logic: Include users when Page path and screen class contains /product-name/ or /services/specific-service.
• Use Case: Someone viewed your "Professional Web Design Services" page. You can remarket to them with ads featuring portfolio highlights and a direct call-to-action to book a consultation about web design.

2. Highly Engaged Users

These are users who love your content but may not have converted yet. They are a great audience for top-of-funnel promotions or brand-building campaigns.

• Logic: You can define this in several ways. One simple way: Include users with session_start event count > 3 (meaning they've visited multiple times).
• Use Case: Show these highly engaged users ads about your brand’s mission, customer testimonials, or special offers reserved for your "best fans." The goal is to build loyalty and stay top-of-mind.

3. Users from a Specific Geographic Location

Perfect for local businesses or promotions tailored to a certain region, city, or country.

• Logic: Include users when Geography -- Country exactly matches "United States" AND Geography -- Region contains "California".
• Use Case: A restaurant in Los Angeles can run a remarketing campaign with a time-sensitive dinner special exclusively for users who have visited their site from within Southern California.

4. Content Readers Who Haven't Converted

These are people who read your blog or resources. They are likely in the research phase and can be moved closer to converting with the right offer.

• Logic: Include users when Page path contains /blog/ and then add a group to exclude users who triggered a purchase or generate_lead event.
• Use Case: Remarket these users with ads offering a relevant, lead-generating asset - like a webinar, ebook, or free consultation - related to topics they read about to move them further down the funnel.

5. High-Value Purchasers

If you're an e-commerce store, you want to bring back customers who have spent a lot with you in the past.

• Logic: Include users when purchase event had a parameter of value that was greater than a certain threshold, like 100 ($).
• Use Case: Show these past high-spenders ads for new arrivals in premium categories or offer them an exclusive "VIP" discount to encourage a repeat purchase.

Activating Your Audience in Google Ads

Creating an Audience in GA4 is half the battle. Now, you’ll need to tell Google Ads to actually use it. After waiting a day or two for the audience to populate, log in to your Google Ads account.

1. Navigate to Tools & Settings >> Shared Library >> Audience Manager.
2. You should see the audience you built (e.g., "Cart Abandoners - Last 30 Days") listed with "Google Analytics" as the source.
3. Now, when you create a new display, YouTube, or search campaign, you can attach this audience at the ad group level under Browse >> How they have interacted with your business >> Website visitors. They are ready to go.

Final Thoughts

Creating a remarketing audience in Google Analytics is a straightforward yet incredibly powerful way to engage with visitors who have already shown interest in your brand. Whether you're reminding them about an abandoned cart or offering an exclusive deal to past purchasers, these targeted lists are a cornerstone of efficient digital marketing.

While setting up these audiences in GA4 and Google Ads is a fantastic first step, getting a true, end-to-end view of performance often requires juggling multiple tabs - GA, Google Ads, Shopify, and your CRM - to piece together the full story. That's why we wanted to streamline that process. We built Graphed to connect all your marketing data in one place. You can instantly ask questions like "How did my remarketing campaign for cart abandoners affect Shopify revenue this month?" and get the automated insights in seconds, saving you from the weekly grind of manual reporting.
