Remarketing (also known as retargeting) is a digital marketing technique that involves targeting users who have previously interacted with a website or brand, but have not yet made a purchase or completed a desired action.

Remarketing works by using cookies or other tracking technologies to identify users who have visited a website or engaged with a brand in some way, such as by adding items to a shopping cart or viewing a specific product page. These users are then targeted with ads or other marketing messages across various channels, such as social media, search engines, or display networks.

The goal of remarketing is to encourage users to return to a website or complete a desired action, such as making a purchase or filling out a form. By targeting users who have already shown an interest in a brand or product, remarketing can be a highly effective way to improve conversion rates and drive revenue.

However, remarketing can also be seen as intrusive or annoying by some users, especially if they feel that they are being followed or targeted too aggressively. As a result, many companies are now using more subtle and personalized remarketing tactics, such as customized email campaigns or targeted messaging based on user behavior.
