A lookalike audience is a Meta/Google audience built from your existing clients, used to target new prospects who share similar characteristics, typically producing 30-50% lower CPLs.
A lookalike audience is generated when you upload a list of existing clients (or high-value leads) to Meta or Google and the platform identifies millions of users with similar digital footprints. For UK financial advisers, lookalikes built from enrolled-client lists typically produce 30-50% lower CPLs than interest-only targeting. Quality depends entirely on the seed list — cleaner data means better lookalikes.
