To show ads to people who have visited your marketplace, add the AdWords remarketing tag to your marketplace. The tag is a short snippet of code that adds your website visitors to remarketing lists; you can then target these lists with your ads.
If your website has a Google Analytics tag, you can use that tag instead and skip adding the AdWords remarketing tag.
