Nailing audience targeting is like hitting the bullseye in a dart game — it takes years of barroom skill training, the ability to disregard the cheap beer, and fancy foot wisdom on knowing how to plant them for a good throw. Ad creation and audience targeting are a bit like that. You’re not just sending out ads willy-nilly—you’re connecting with people who actually want what you’re offering. Custom and lookalike audiences are powerful tools that help you reach those people who “get” your brand.
Think of it as harnessing the psychology of tribe mentality—people love to belong to something that feels personal, where they find shared interests and identities (Uscreen). So, what exactly are custom and lookalike audiences, and when should you use each? Let’s dig in and see how to use these tools to run ads that don’t just reach people—they resonate and create a tribe that praises your product as the golden calf.
The Game-Changing Power of Audience Segmentation
Audience segmentation is a paradigm-shifting resource for digital campaigns. By splitting up your audience, you’re making sure your message hits the people most likely to connect with it. That the punch lands like a K.O. one. Custom and lookalike audiences take segmentation to another level: custom audiences help you stay in touch with people who are already in your corner, while lookalike audiences reach brand-new people who are basically “brand-fans-in-waiting.” Platforms like Facebook and Google Ads are all over this approach because it works.
Here’s the lowdown: custom audiences let you go after people who’ve interacted with you before—whether they’ve visited your site, signed up for an email, or made a purchase. Lookalike audiences help you take that vibe and find new people who are just as likely to engage. When used together, you’ve got a full-court press on reaching the right audience.
What is a Custom Audience?
A custom audience is built from your brand’s personal “inner circle”—users who already know you, or at least took a look your way. These audiences come straight from your own data, like email lists, website traffic, or customer info. So, custom audiences are for targeting those who’ve already interacted with your brand in some way. You’re speaking directly to people who showed interest and giving them a nudge to act.
Perks of Using Custom Audiences
Custom audiences let you zero in on those already familiar with your brand, creating campaigns that feel personal. It’s not just about showing people products—it’s about re-engaging with those who are a step away from converting. Personalization is everything here. When you tailor ads to past actions, like revisiting a product they checked out or an item they left in their cart, your message feels relevant. Data shows personalized ads increase user engagement because they tap into specific needs and behaviors (Lexology).
How to Crеatе a Custom Audiеncе
- Upload Data to Advеrtising Platform: Import your usеr data into your prеfеrrеd advеrtising platform (е.g. Googlе Ads and Facеbook Ads).
- Crеatе Custom Audiеncе: Usе thе platform’s tools to crеatе a custom audiеncе based on your uploadеd data.
- Targеt Your Audiеncе: Usе your custom audiеncе to targеt your ads to thе specific usеrs you want to reach.
When to Use Custom Audiences
- Retargeting Website Visitors: Think about when you browse a site and then see ads following you around online. That’s retargeting in action, and it works. With custom audiences, you can show people a little reminder ad for the product they left in their cart.
- Targeting Existing Customers for Upsells: Custom audiences make it easy to reach out to people who’ve bought from you before with new or related products. Think about it as gently nudging them to level up their experience.
- Segmenting Based on Engagement: Custom audiences also let you break things down. Target specific subsets, like people who watched your latest video or downloaded a freebie, with offers that align with their actions.
What is a Lookalike Audience?
A lookalike audience, on the other hand, is like Custom’s adventurous cousin. It’s built to find new people who have similar characteristics to those in your custom audience. Platforms like Facebook use algorithms to analyze the traits of your custom audience, then go searching for users who fit the bill. With lookalikes, you’re expanding your reach while still keeping it relevant.
Why Lookalike Audiences Are Gold
Lookalikes are the answer when you want to reach fresh faces without losing the personal touch. They help you discover new customers who have a good chance of converting because they resemble your existing audience. And they’re scalable, making them a smart play for customer acquisition.
For instance, if your custom audience is made up of past buyers who value sustainability, a lookalike audience would bring in new people who align with that eco-friendly mindset. You’re not just broadening your audience – you’re making sure new fans have shared values.
Lookalike Audience Use Cases
- Discovering New Customers: Want to grow your brand? Lookalike audiences help you reach people who haven’t found you yet but have the potential to become loyal customers.
- Scaling Successful Campaigns: If a campaign is killing it with a custom audience, replicate it to a lookalike to bring in similar, high-quality leads.
- Optimizing Lead Generation: Finding users similar to high-value customers helps you fill the pipeline with people who are ready to take action.

Key Differences Between Custom Audience and Lookalike Audience
Source of Audience Data
Custom audiences are crafted from your data—site visits, emails, purchases. Lookalike audiences? They’re platform-driven, using your custom audience as a model to find new people who match.
Purpose and Reach
With custom audiences, the goal is re-engagement—connecting with people who already know you. Lookalikes are about expansion—reaching out to people who’ve never heard of you but could be interested.
Precision and Targeting
Custom audiences offer extreme precision since they’re based on known users. Lookalikes, while still targeted, are more about casting a wider net with a built-in filter for relevance.
Scalability
Lookalikes are made for scaling up. They allow you to take a successful audience model and apply it to a bigger group, getting the best of both reach and relatability.
When to Use Custom Audience vs Lookalike
Retargeting and Engagement Scenarios
When you want to re-engage or retarget, custom audiences are your go-to. These are people who’ve interacted with your brand, even if it was just a quick peek at your site. With custom audiences, you can pull them back in with tailored ads, reminding them why they showed interest in the first place.
Customer Acquisition and Scaling Scenarios
Need to grow your customer base? Lookalike audiences are ideal for discovering new people with similar tastes, habits, or demographics. They help you scale your success by reaching new faces that resemble your top customers.
Using Both for a Full Strategy
Don’t limit yourself to one or the other. For optimal rеsults, consider combining both custom and lookalikе audiеncеs in your marketing campaigns. Start with custom audiences to convert the warm leads and crеatе highly targеtеd campaigns, then expand with lookalike audiences to scale your campaigns and build a broader community of engaged users. The two combined give you the power to stay personal and reach new people simultaneously.

Custom vs Lookalike Audience, Made Easy
Both custom and lookalike audiences play a one-of-a-kind role in reaching and sinking their tentacles into the right people. Custom audiences give you a direct line to folks who already have a reason to like you, making re-engagement easy. Lookalike audiences, on the other hand, let you step outside the usual suspects and connect with potential new fans who share the same vibe. Together, they’re a winning strategy—one that taps into tribe mentality, data-driven insights, and segmentation.
By learning when and how to use each, you’re setting up a campaign that feels personal, precise, and powerful — and full of protein and promise, very profitable and proficient. Dive in, test the waters, and let custom and lookalike audiences do the heavy lifting for your brand.
