Want to get more out of your Facebook ads? If your goal is higher engagement — more clicks, likes, shares, and conversions — then it’s time to stop targeting cold audiences and start speaking directly to people who already know your brand.
That’s where Custom Audiences come in.
Custom Audiences are one of Facebook’s most powerful tools. They let you reconnect with people who have interacted with your business before. Whether they visited your website, followed you on Instagram, or made a purchase, these users are already familiar with you and are much more likely to engage with your ads.
Let’s explore how to use Custom Audiences to increase engagement and get better results from your Facebook campaigns.
What Are Custom Audiences?
Custom Audiences allow you to target specific groups of people based on how they have interacted with your business.
These interactions can include:
-
Visiting your website;
-
Watching your videos;
-
Engaging with your social posts;
-
Adding products to their cart;
-
Making a purchase.
Instead of advertising to people who have never heard of you, focus on those who already know your brand. This makes your ads more relevant and increases the chances of engagement.
Poor audience targeting is one of the biggest reasons Facebook ads fail to deliver: this beginner-friendly guide breaks down how to do it right.
Why Custom Audiences help maximize engagement
Reaching a warm audience is one of the best ways to improve ad performance. These are people who have already shown interest in your business. When you follow up with a relevant ad, they are much more likely to take action.
Here are some ways Custom Audiences help increase engagement:
-
Retarget website visitors who didn’t convert;
-
Remind cart abandoners to complete their purchase;
-
Reconnect with past customers through special offers;
-
Reach social media followers who have interacted with your posts.
Focusing on people who are already interested in your brand improves ad efficiency and helps drive better results.
How to use Custom Audiences to increase engagement
Here are practical strategies to help you get the most out of custom audiences:
Retarget social media engagers
People who like, comment on, or share your posts have already shown interest. Running ads to this group helps keep them engaged with your content and your brand.
Tip: personalize your message based on how they engaged. If someone liked a product post, show them that product again with a discount or new offer.
Reach website visitors
By installing the Facebook Pixel, you can track visits to your website and create audiences based on that activity.
Tip: show ads related to the pages they visited or products they viewed. This keeps your content relevant and top of mind.
Recover abandoned carts
Many online shoppers leave items in their cart without checking out. Custom Audiences let you target these users with reminders.
Tip: highlight the items they left behind in your ad. Add a time-sensitive offer or free shipping to encourage them to return and complete the purchase.
Re-engage previous customers
Your existing customers already trust your brand. They’re more likely to buy again, especially if you offer them something new or exclusive.
Tip: promote related products, loyalty rewards, or upcoming launches to your previous buyers. Keep them in the loop and make them feel valued.
Target based on specific actions
You can create Custom Audiences based on actions like signing up for a newsletter, watching a video, or downloading a guide.
Tip: use follow-up ads that directly relate to those actions. For example, if someone downloaded a guide about skincare, show them products that align with that interest.
Best practices to maximize engagement with Custom Audiences
Follow these strategies to get the best possible results from your campaigns:
-
Make ads personal: Tailor your messaging to each audience segment based on their past behavior.
-
Use Dynamic Product Ads: These automatically display products that users viewed or added to their cart.
-
Adjust frequency: Show ads enough to stay visible but not so often that they become annoying.
-
Exclude recent buyers: Avoid targeting people who just made a purchase. This saves budget and keeps your ads relevant.
-
Build lookalike audiences: Once you have a strong Custom Audience, create a Lookalike Audience to find new potential customers with similar traits.
Test different ads to see what works best. Keep improving your ads so they stay effective and relevant.
