Does Google have lookalike audiences?
Similar segments and customer match, yes — built from your own data.
The short answer
Similar segments and customer match, yes — built from your own data.
Upload a customer list and Google can find people who resemble them, or target your existing customers directly for retention and upsell.
The quality depends entirely on the list. A list of everyone who ever bought includes your worst customers; a list of repeat buyers is far more useful.
