Remarketing is a tool that allows you to “jog the memory” of a previous site visitor. When someone visits your site and leaves without making a purchase or signing up, remarketing reaches out to them later in a different online location, reminding them of their interest in your product or service. Relevant ads are shown as they browse the web, use mobile apps, or search Google. This allows you to recapture the attention of someone who previously didn’t convert because the timing wasn’t right.
