Remarketing options can vary across advertising platforms but you’ll normally find variations of the following:
Standard remarketing: Show display ads to previous visitors as they browse the web and/or apps.
Dynamic remarketing: Automatically show the product or service people viewed in your display ads.
Customer list remarketing: Show remarketing ads to new audiences that show similar interests and behaviours as your existing customers.
In Google Ads, you can also use remarketing lists for search ads (RLSAs) to show text ads to previous visitors when they search for something relevant in Google Search.
