In this article we will walk you through what Lookalike Audiences are, how they work, the benefits and how to create and optimise them for better results. Let’s get into the nitty gritty of Lookalike Audiences and how they can change your digital marketing.

1. What are Lookalike Audiences

A Lookalike Audience is a group of people who share the same characteristics, behaviours and interests as an existing audience you have identified as valuable, such as customers, email subscribers or website visitors. These audiences are created using machine learning algorithms that look at your existing customers data to find people who “look like” them.

For example, if you have a list of customers who regularly buy from your website, a Lookalike Audience would be people who show similar online behaviours, preferences and demographics. This allows marketers to reach people who haven’t interacted with the brand yet but are likely to be interested in it.

Lookalike Audiences are used on platforms like Facebook, Instagram and Google Ads. By utilising these platforms’ vast data and advanced machine learning, marketers can increase their chances of reaching a high quality audience that will engage, convert or become customers.

2. How Lookalike Audiences Work?

A Lookalike Audience is built off of a “source audience” which is the foundation for the lookalike model. Here’s how it works:

Choose a Source Audience: First a business chooses a source audience which can be existing customers, website visitors, app users or people who engaged with previous ad campaigns. Facebook recommends a source audience of at least 1,000 people to get accurate results but a larger source will get better quality.
Machine Learning Analysis: The algorithm analyzes the source audience to find common characteristics, behaviors and demographics. Key data points are age, location, online behaviors, purchase history and device usage.
Audience Matching: The algorithm then searches for people in the broader population who have similar attributes to the source audience. For example if the source audience is people who have bought athletic wear online the algorithm may create a lookalike audience of people who have shown interest in fitness, health or similar brands.
Audience Segmentation: Lookalike Audiences can be segmented by similarity. Platforms like Facebook allow you to choose a percentage range for similarity, smaller percentages will give you more precise matches and larger percentages will give you broader reach by including less similar people.

By analyzing user behavior patterns Lookalike Audiences allow you to target people who are most likely to engage with your content, products or services.

Frequently Asked Questions

What is a Lookalike Audience, and how does it work?

A Lookalike Audience is a group of people who share similar characteristics, behaviors, and interests with an existing audience of your customers, subscribers, or website visitors. Platforms like Facebook and Google use machine learning to analyze data from your source audience, identifying people who “look like” them. The algorithm studies demographics, behaviors, and interests to create a list of users who may be interested in your products or services. This allows marketers to expand their reach to new, relevant customers who are likely to engage and convert.

What is the difference between a Custom Audience and a Lookalike Audience?

A Custom Audience consists of people you already know—such as current customers, website visitors, or email subscribers. You upload your data or set up tracking on your site to reach them with targeted ads. A Lookalike Audience, on the other hand, is built based on the characteristics of your Custom Audience, but it targets new individuals who have not yet interacted with your brand. Essentially, a Lookalike Audience is a group of new people who resemble your existing audience and are likely to be interested in your business.

How can a Lookalike Audience benefit my advertising campaigns?

Lookalike Audiences provide multiple benefits to advertisers by enabling you to reach new, relevant people who are more likely to engage with your brand. This approach increases reach, boosts engagement rates, and drives conversions, making it ideal for improving ROI. Additionally, Lookalike Audiences allow for efficient budget allocation by focusing your ad spend on qualified leads. The similarity to your best customers enhances the likelihood of finding new loyal customers while helping you scale your campaigns effectively.

How do I create a Lookalike Audience on Facebook?

To create a Lookalike Audience on Facebook, follow these steps:

Go to Facebook Ads Manager.
Choose “Audiences” and click on “Create Audience,” then select “Lookalike Audience.”
Select your source audience, such as a Custom Audience from customer lists, website visitors, or past campaign engagers.
Choose a location (country or region) for the Lookalike Audience.
Adjust the audience size using the similarity percentage (1%-10%), where smaller percentages provide a more specific match.
Once set up, you can target the Lookalike Audience in your ad campaigns to reach new people who are similar to your best customers.

What factors should I consider when choosing the source audience for a Lookalike Audience?

The quality of your source audience greatly impacts the effectiveness of a Lookalike Audience. Choose a source audience that represents your ideal customers or those who are most engaged. For instance, a source audience of loyal customers or people who have made repeat purchases can yield better results than a general audience. Facebook recommends a source audience size of 1,000 people for best results, but the larger and more relevant the source, the more accurate the Lookalike Audience will be. Regularly updating your source audience to reflect recent engagement trends is also beneficial.

What percentage range should I select for my Lookalike Audience, and what does it mean?

The percentage range for a Lookalike Audience determines how closely the new audience matches your source audience. A 1% range is the most similar to your source audience, while a higher percentage broadens the reach, including users with similar but not identical characteristics. A 1%-3% range is typically ideal for targeting highly relevant users, while 5%-10% ranges can be used for campaigns focused on scaling reach. Testing different ranges allows you to find the best balance between reach and relevance for your specific goals.

How do Lookalike Audiences differ from Interest-Based Targeting?

Lookalike Audiences are based on the real data of your existing audience, identifying people with similar characteristics, behaviors, and interests, whereas interest-based targeting is broader, relying on general interests and behaviors selected within the ad platform. Lookalike targeting is typically more precise because it is modeled on actual customer data, making it more effective for reaching users with a higher likelihood of converting. In contrast, interest-based targeting is helpful for broader brand awareness and reaching people with interests related to your industry or products.

Can I use Lookalike Audiences in conjunction with other targeting strategies?

Yes, using Lookalike Audiences alongside other targeting options, such as geographic, demographic, and interest-based targeting, can help further refine your audience and increase relevance. For example, you might use a Lookalike Audience in combination with a specific geographic location or age range to match the profile of your target customers. Combining strategies can help you reach new potential customers who share similar traits with your existing audience while narrowing down criteria to fit your campaign goals.

What are common mistakes to avoid when using Lookalike Audiences?

Common mistakes include using a low-quality source audience, choosing a percentage range that’s too broad, neglecting to monitor performance, and failing to update the source audience. Using a source audience that doesn’t closely represent your target customers may lead to poor results. Similarly, if your Lookalike Audience range is too broad, it may dilute the quality of the audience. Neglecting to track performance metrics, such as engagement and conversion rates, can prevent you from optimizing your campaigns effectively. Regularly updating the source audience is also crucial to maintaining relevance.

How can I improve the performance of my Lookalike Audience campaigns?

To enhance your Lookalike Audience campaign performance, start with a high-quality source audience that reflects your best customers. Experiment with different similarity percentages, testing 1%-3% for precision or 5%-10% for reach. Monitor your campaign metrics, such as click-through rates, conversions, and ROI, to identify areas for optimization. Use A/B testing with various ad creatives, formats, and messaging to discover what resonates best with your audience. Regularly refresh the source audience, especially if you notice changes in audience behavior or new customer trends.
