In more detail
Lookalike audiences are a paid social targeting tool on platforms like Meta, TikTok, and LinkedIn. You upload a source, or seed, audience: past buyers, email subscribers, page engagers, or website visitors. The platform analyzes what those people have in common (interests, demographics, online behavior) and finds new users who match that profile. The point is to reach cold prospects who resemble people who already like your brand, instead of guessing at interests manually. The quality of the seed list matters more than its size. A small list of your best customers usually beats a big list of random sign-ups.
Example
Say you upload your 2,000 highest-spending customers as the seed. On Meta you can then create a 1 percent lookalike, which targets roughly the 1 percent of users in your country who most closely match that group. A 1 percent audience is tighter and more similar to your seed, while a 5 or 10 percent audience is broader and reaches more people but matches less precisely.
