The platform algorithms can work with that data and actually start lending a hand in your targeting efforts. In Google and YouTube, they’re called Similar Audiences, and in Facebook and Instagram, they’re called Lookalike Audiences. In both cases, you decide which bucket to use as the source, the algorithm then looks deep into who those people are, and then matches up others in your specified geographical range who are most similar to them (and thus more likely to care about what you have to offer).
