Remarketing is a feature that lets you reach people who have previously visited your site, and show them relevant ads across the web or when they search on Google. When people leave your site without buying anything, for example, remarketing helps you connect with these potential customers again. You can even show them a tailored message or offer that will encourage them to return to your site and complete a purchase.
Use remarketing to match the right message to the right people at the right time. Here’s how: You add a piece of code (remarketing tag) to all of the pages of your site. Then, when shoppers come to your site, they’ll be added to your remarketing lists. You can later reach out to these potential buyers while they search on Google or browse other websites.
