What does retargeting do?

Retargeting, also known as remarketing, specifically targets users who have previously interacted with your website or app. It works by placing a cookie on a user's browser when they visit your site. Later, as that user browses other websites that are part of an ad network, ads for your business are displayed to them, encouraging them to return. This strategy is highly effective because it focuses on individuals who have already shown interest in your offerings, increasing the likelihood of conversion. The option about bringing brand-new users describes prospecting, not retargeting. The option about matching demographics of past customers describes audience targeting, which can be part of a broader strategy but isn't the core definition of retargeting.
