Remarketing is a digital marketing strategy that targets ads to users who have previously interacted with your website or mobile app. By placing a small piece of code, or pixel, on your site, you can track visitors and display personalized ads to them as they browse other websites or use social media. This approach keeps your brand top-of-mind, encouraging potential customers to return and complete desired actions, such as making a purchase or filling out a contact form. Remarketing campaigns can be customized based on user behavior, making advertising highly relevant and effective. This targeted method enhances engagement and increases conversion rates by re-engaging interested users who initially left your site without converting.
