Google Dynamic Remarketing Ads
Target past visitors interested in the products you are selling by retargeting them through display ads.
Remarketing allows you to show ads to people who have previously visited your online store. Dynamic remarketing takes this a step further, letting you show previous visitors ads that contain products they viewed on your online store or added to their cart. With messages tailored to your audience, dynamic remarketing helps you increase sales by bringing previous visitors back to your online store to complete what they started.
