The definition
An ad-platform audience built by finding people statistically similar to a source list, like your customers. Quality depends entirely on the source.
Why it matters to an owner
Feed it your best customers, not your whole list. The algorithm clones whatever you hand it, including your mistakes.
This is the work. Want it done?
Everything here is free to use yourself. That’s the point. If you’d rather a senior marketer just handle it, in your accounts and your name: 20-minute call, no pitch deck.
