Also called retargeting, Google remarketing is the technology that enables your Google Ads to follow potential customers as they move across the internet. When a user visits, a small snippet of code on your website adds them to a remarketing list. Then when they visit another website that uses the Google Ad network, they are served your ad. Google allows you to customize who sees your remarketed ads. For example, you can prioritize new or returning customers.
