Google Remarketing effectively increases conversions and revenue by showing ads to people who have previously visited your website, or interacted with your products. Google Display Remarketing is more aligned to middle funnel activities, helping brands increase awareness and consideration. Display Remarketing ads are shown via the millions of websites contained in the Google Display Network aka GDN and the Google partner websites. Also, it is much cheaper since it targets a narrow audience list rather than a wide one, increasing the chances of conversions, thereby improving ROI.
