Final answer:
Re-targeting is indeed based on the requirement that a user has previously visited a company's website, which allows the company to display targeted ads to that user based on their browsing behavior on the site.
Step-by-step explanation:
The statement that re-targeting requires the user to have been to your company's website is true. Re-targeting, also known as remarketing, is a type of online advertising that helps companies to display ads to users who have previously visited their website. The goal is to reach individuals who have shown an interest in the products or services by visiting the site but did not make a purchase or complete a desired action. This is achieved by placing cookies on the user's device when they visit the website, which then informs re-targeting platforms to serve specific ads based on the pages and products the user has interacted with.
