What Are AI Lookalike Audiences?

AI lookalike audiences are targeting segments built by machine learning. You feed the AI a “source audience” — your best customers, your highest-LTV buyers, or your most recent purchasers — and it finds new people who share the same demographic, behavioral, and interest signals. These lookalikes are far more likely to convert than cold targeting.

Step 1: Define Your Source Audience

Upload your customer list — ideally your best customers, not all customers. The AI will find people who look like your top 20%, not your average buyer. Quality of source audience determines quality of lookalike.

Step 2: Let AI Find The Patterns

Machine learning identifies the signals that define your source audience: age, location, interests, purchase behavior, device usage, and dozens of other data points. It then matches those signals against the broader population to find lookalikes.

Step 3: Test Audience Size & Narrowness

Start with a 1% lookalike (the closest match) and test broader 2-5% audiences. Narrower audiences cost more per reach but convert better; broader audiences scale further but convert at a lower rate. Test both and let the data decide.

Step 4: Refresh & Iterate

Lookalike audiences fatigue over time. Refresh your source audience monthly with your newest best customers, and let the AI rebuild the lookalike. This keeps your targeting sharp as your customer base evolves.

We build and refresh AI lookalike audiences for every campaign — so your ads reach people who look like your best customers, not random clicks from people who'll never buy.

Test at least 2–3 ad creatives per ad group; the algorithm rewards fresh creative.
