What it means

A Lookalike Audience is a target segment generated by ad platforms containing users who mirror the characteristics and behaviors of your existing best customers, typically built from a source list like past purchasers or high-value leads.

Platforms like Meta and Google analyze thousands of signals in the source audience to find statistically similar users at scale, making it one of the most effective ways to find new customers who look like the ones you already have.

Finds new customers efficiently

It targets strangers who statistically resemble your best existing customers, not a random cold audience.

Scales what already works

It lets you expand reach without abandoning the profile that’s proven to convert.

Improves as your data improves

The better and larger your source list, the sharper the lookalike match becomes.

DNA’s Take

DNA's Take: We build lookalike audiences from your highest-value customer segments, not just anyone who converted, so prospecting budget is aimed at the people most likely to become genuinely profitable customers.
