Use Remarketing too! Remarketing is a fundamental concept of E-Marketing. This involves showing advertising to people who have visited your website. Google allows you to define remarketing lists (we often make a list by product or service universe of our website). Once the list is defined, Google asks you to put a marker on your website. It is this marker that will add a cookie on the visitor’s machine, which will then identify them wherever they are on the Web. You can then imagine advertisements that will appear on Display Network sites only to people recognized as former visitors to your site. When we know the importance of redundancy in communication, we quickly understand the opportunity that Google Ads offers.
