For retargeting to work, it is necessary to place a pixel code on your website. This code creates a list of people who visit the site by setting anonymous retargeting “cookies” in their browsers. The list allows retargeting ads to display to potential customers while they visit other websites. Ads can adapt to different geographies, demographics, and other factors with tailored messaging, imagery, products, and experiences to enhance their relevance (and thus, engagement). Every time the customer sees your retargeting ads, the brand gains traction and more recognition.
