Retargeting is an advertising technique that shows ads to people who have already visited a website but did not make a purchase. You have likely experienced this: you visit an online store, look at a product, and then that same product follows you on social media or other sites. That is retargeting. It works using cookies and tracking pixels that record user behavior. Platforms like Google Ads and Facebook Ads allow you to set up retargeting campaigns to recover potential customers and increase conversions. It is a powerful strategy to remind users to return and complete their purchase.
