Google Remarketing
Remarketing is the option which shows your google ads to users who have visited your site in past, as and when they see google adwards while browsing the any web pages.
Technically google stores visited website details in your computer and whenever you surf any web page having google adwards, it shows your ad as matched based on remarketing concept.
When you use remarketing, you’ll tag pages of your site that correspond to certain categories you want to promote.
