Remarketing is a creative, innovative way to target people you know are searching for businesses like yours. This is an incredible new method for matching up the right ad with the right people. Remarketing lets your advertising identify people who have already visited your website during their online browsing. The pages they have clicked on help you to know what those viewers are interested in. Then you can launch an advertising campaign which makes your ad pop up when your previous online visitors are browsing across any other sites on the Google Display Network.
So your ad is appearing in front of people who have proved they are clicking on your site, and interested in your products or services - as they are going about their regular internet use, at home or at work. This is a highly effective strategic tool to get your ad in front of the eyes of genuinely relevant consumers.
