Lookalike Audiences
Lookalike Audiences are groups of people who resemble your best customers. You provide Google or Facebook with your customer list or people who've converted, and the platform finds similar people based on interests, behavior, and demographics.
Why it matters for your business
Lookalike audiences let you find more high-quality leads without manually defining who your ideal customer is. If you have a list of 100 customers, Google/Facebook can find thousands of similar people — usually with lower CPL than cold audiences.
In practice
A cleaning service has a list of 50 satisfied customers. They create a Lookalike Audience in Facebook. Facebook finds 10,000 people who look similar (same location, interests, age range, buying behavior). Ads to this audience typically convert better than generic local ads.
Common questions
How many customers do I need to create a Lookalike Audience?
Facebook requires at least 100 people in your seed list. Google Ads requires at least 500 for Lookalike Audiences. The bigger your list, the better the lookalikes usually perform.
What's a good Lookalike Audience size?
Start broad (1% of your country) and narrow over time. As you get data on what works, you can refine to smaller, higher-intent audiences.
