How to Retarget on Facebook Ad

Getting traffic to your website is exciting, but seeing those visitors leave without making a purchase can be frustrating. The good news is that you don't have to let those promising leads slip away. This is where Facebook retargeting comes in, allowing you to re-engage people who have already shown interest in your brand. In this guide, we'll walk you through exactly how to set up a powerful retargeting campaign from scratch.

What Is Facebook Retargeting (and Why Does It Work So Well)?

Facebook retargeting, sometimes called remarketing, is the practice of showing targeted ads to people who have already interacted with your business online. These interactions could be visiting your website, watching one of your videos, engaging with your Instagram profile, or being on your email list.

Think of it like this: A customer walks into your physical store, looks at a specific jacket, tries it on, and then leaves without buying it. Retargeting is like having a helpful (and not creepy) store associate gently remind them about that jacket later in the day, maybe mentioning it's the last one in their size or that it pairs perfectly with a shirt they also looked at.

It's incredibly effective because you’re no longer advertising to a cold audience of strangers. You're talking to a warm audience - people who already know who you are. This leads to several powerful benefits:

• Higher Conversion Rates: Warm audiences are far more likely to convert than people who have never heard of you.
• Lower Cost Per Acquisition (CPA): Because your audience is so targeted, you often spend less to acquire each new customer.
• Increased Brand Recall and Trust: Staying top-of-mind builds familiarity and trust, making customers more comfortable buying from you.

The Foundation: Getting Your Facebook Pixel Ready

Before you can retarget website visitors, you must have the Facebook Pixel (now an entire dataset through the Events Manager) installed on your site. This small snippet of code is the engine behind your retargeting efforts. It tracks visitor activity, allowing you to create audiences based on specific actions they take.

Finding and Installing the Pixel

If you don’t have it installed yet, setting it up is your first step. It's more straightforward than it sounds.

1. Navigate to your Events Manager in your Facebook Business Suite.
2. Click the green plus icon labeled "Connect Data Sources" and select "Web."
3. Give your Pixel a name (e.g., "Your Company's Website Pixel") and enter your website URL.
4. Facebook will then give you options for installation. The easiest way is often through a partner integration. If you use a platform like Shopify, WordPress, or Squarespace, you can usually just copy and paste your Pixel ID into a designated field in your website's admin panel.
5. If you don't use a partner platform, you can install the code manually by adding it to the header section of your website’s code, or email the instructions to a developer.

To confirm it's working, install the Meta Pixel Helper extension for Google Chrome. Visit your website, and if the extension icon turns blue with a small green notification, your pixel is active and ready to collect data.

Creating Your First Retargeting Audience (The "Who")

With your pixel in place, you can now tell Facebook exactly who you want to retarget. You do this by creating a Custom Audience. This is a group of people who have taken specific actions that you define.

1. Go back to your Facebook Business Suite and navigate to the "Audiences" section.
2. Click the blue "Create Audience" button and select "Custom Audience" from the dropdown.
3. You'll see a list of sources. For retargeting, your primary source will be "Website."

From here, you can create all kinds of powerful audience segments. Here are some of the most effective ones to start with:

1. All Website Visitors

This is the broadest retargeting audience but a great starting point. You can create an audience of everyone who has visited your website within a specific timeframe (e.g., the last 30, 60, or 90 days).

• How to set it up: Under "Events," keep the default "All website visitors." Choose your desired retention window (30 days is common for this group).
• Ideal for: General brand awareness, announcing new products, or promoting top-of-funnel content to people already familiar with your brand.

2. Visitors of Specific Pages

This lets you get much more specific. Instead of targeting everyone, you can target only the people who visited certain product pages, pricing pages, or categories on your website. This shows you exactly what they are interested in.

• How to set it up: Change "All website visitors" to "People who visited specific web pages." Then, enter the keywords from the URL of the page you want to target (e.g., if the URL is yourstore.com/products/blue-running-shoe, you can use the rule "URL contains blue-running-shoe").
• Ideal for: Showing an ad with a testimonial about that specific product or highlighting a benefit they might have missed.

3. "Add to Cart" but Did Not Purchase (Cart Abandoners)

This is one of the highest-intent audiences you can target. These people liked an item enough to add it to their basket but didn't complete the checkout for some reason - perhaps they got distracted, had second thoughts about shipping costs, or just needed one more nudge.

• How to set it up: You’ll use a combination of rules. First, under "Events," select the AddToCart standard event. Then, click "Exclude people" and create another rule to exclude people who completed the Purchase standard event. This ensures you're only targeting those who added to their cart but didn't buy.
• Ideal for: Highly specific ads! Mention the item they left behind, offer a small discount or free shipping to win them back, and remind them why they wanted it in the first place. This is where you use your strongest call to action.

4. Video Viewers

If you use video content in your marketing, you can retarget people based on how much of your video they watched. Someone who watched 75% or 95% of your video is much more engaged and interested than someone who only watched for 3 seconds.

• How to set it up: In the "Create a Custom Audience" menu, choose "Video" as your source. You can then select people who watched a certain percentage or length of your videos (e.g., 50%, 75%, 95%).
• Ideal for: Moving people down the funnel. If they watched an educational video, you can retarget them with an ad for a related product or a webinar sign-up.

5. Social Media Engagers

This lets you target people who have interacted with your Facebook Page or Instagram Profile. This includes actions like liking a post, sending a message, saving a post, or visiting your profile.

• How to set it up: Choose "Facebook Page" or "Instagram Account" as your source. You can target everyone who engaged or narrow it down to people who took specific actions, like "People who sent a message to your Page."
• Ideal for: Building a loyal audience and encouraging followers to take the next step, like visiting your website or joining your email list.

Building the Retargeting Campaign (The "How")

Once you've saved your Custom Audience (give it a descriptive name like "Website Visitors - 30 Days" or "Cart Abandoners - 7 Days"), it’s time to build the campaign that will use it.

In Facebook Ads Manager, create a new campaign. Here’s a quick walkthrough:

1. Choose Your Objective: For retargeting, you’ll most often use the "sales" objective (which used to be called "Conversions"). This tells Facebook's algorithm to find the people in your audience who are most likely to make a purchase.
2. Define Budget and Schedule: Set your daily or lifetime budget. You don't need to start with a large budget for retargeting since the audiences are typically smaller and more targeted.
3. Select Your Audience (At the Ad Set Level): This is the key step. In the "Audience" section of your ad set, you'll see a field called "Custom Audiences." Start typing the name of the audience you just created and select it from the list.
4. Demographics & Placements: You can generally leave the location, age, and gender targeting very broad, as your Custom Audience has already pre-qualified these people. For placements, "Advantage+ placements (formerly Automatic Placements)" is often fine to start with.
5. Create Your Ad Creative: Now for the ad itself. Remember, your ad copy and creative should be different for a warm retargeting audience than for a cold one. They already know you, so you can tailor your message.

A few ad ideas for different audiences:

• For Cart Abandoners: Use a carousel ad to dynamically show the exact products they left in their cart. Your headline could be something like, "Still thinking about it?" or "Did you forget something?"
• For Product Page Viewers: Remind them of the core benefit. You can show user-generated content, a strong testimonial, or a short video of the product in action.
• For All Website Visitors: Reinforce your brand's unique value proposition. Why should they choose you? This is a great place to showcase your best-selling product or your brand story.

Best Practices for Effective Retargeting

Setting up the campaign is one thing, making it effective is another. Here are a few pro tips to remember:

• Use Frequency Caps: You don’t want to bombard people with your ads. In your ad set settings, you can set a frequency cap to limit how often a single person sees your ad in a given period. It's better to show an ad 3-5 times a week than 10 times in one day.
• Exclude Previous Converters: There’s nothing more annoying than seeing an ad for a product you just bought. In your ad set's audience settings, make sure to exclude the custom audience of people who have already purchased.
• Keep Your Ad Creative Fresh: If your audience sees the same ad every single day, they'll start tuning it out (this is called ad fatigue). Rotate your creatives every couple of weeks to keep things interesting.
• Test Different Time Windows: Experiment with different time windows for your audiences (e.g., 7 days vs. 30 days). Someone who visited your site yesterday is much "hotter" than someone who visited 60 days ago. You might want to bid more aggressively for the more recent visitors.

Final Thoughts

Facebook retargeting is one of the most cost-effective strategies for turning casual browsers into loyal customers. Once you have the technical pieces set up, the real art is in continuing the conversation with your audience by delivering relevant, helpful ads that gently guide them back to complete their journey with your brand.

Of course, knowing if your campaigns are truly effective means keeping a close eye on your performance data. Often, this requires jumping between Facebook Ads Manager, your e-commerce platform like Shopify, and Google Analytics just to connect the dots. We built Graphed to simplify this. Instead of juggling a dozen browser tabs, you can connect your data sources in a few clicks and ask questions in plain English like, "Compare ROI across all my Facebook retargeting campaigns this month" to get a real-time, unified dashboard instantly. This frees you up to focus on strategy, not spreadsheet wrangling.
