Lookalike targeting is an advertising strategy that helps businesses reach new people who share similar characteristics, interests, or behaviors with an existing audience, such as current customers or website visitors. Advertising platforms analyze an eligible source audience to identify other users who may be interested in a business’s products or services.
It is commonly associated with Meta advertising, where the feature is called a Lookalike Audience. Other platforms offer similar audience-expansion capabilities under different names.
Key aspects of lookalike targeting:
Source audience: Uses an eligible audience, such as existing customers, purchasers, or website visitors.
Audience expansion: Helps discover new potential customers beyond the original audience.
Similarity modeling: Uses platform signals and available data to identify people with similar characteristics or predicted behaviors.
Customer acquisition: Supports campaigns designed to attract new customers and generate leads or sales.
Audience size: Depending on the platform, advertisers may choose between narrower, more similar audiences and broader audiences with greater reach.
Campaign optimization: Measures results using metrics such as click-through rate (CTR), conversion rate, cost per acquisition (CPA), and return on ad spend (ROAS).
Privacy compliance: Source data must be collected and used in accordance with applicable laws, consent requirements, and platform policies.
Example:
Suppose a Shopify jewellery store has a list of customers who purchased diamond rings. The store creates an eligible customer audience and uses it as the source for a Meta Lookalike Audience. Meta can then help the store reach new users who resemble that source audience, potentially increasing the number of relevant shoppers.
Why is lookalike targeting important?
It helps businesses expand beyond existing customers, discover new prospects, improve customer acquisition, and scale advertising campaigns.
In short: Lookalike targeting uses an existing audience as a model to help advertisers find new people who may be interested in their products or services.
