Squadhelp's remarketing strategy involves remarketing based on cookies, expanding to include more channels such as Twitter, LinkedIn, Quora, Pinterest, Reddit, and leveraging Google partnerships. The strategy ensures that if a person visits a domain, they will see ads showcasing that domain. Remarketing also exposes people to other domains they may not have seen before. Approximately 35% of Squadhelp's sales have been influenced by these remarketing ads, either through clicking on the ad for the visited domain or clicking on another domain in the ad that was not visited. Overall, the remarketing strategy is effective and works well for Squadhelp.
