Click-through rate, also known as CTR, refers to the number of individuals who, once they have initially clicked and opened a post, ad, or other type of link on a social media platform, continue to click on all of the pages associated with that posting to read and learn more about the subject, purchase a product, or complete some action related to it. It is a valuable tool as it measures and indicates the effectiveness and success of the social media content in convincing people to search out your web properties. Click-through rate is calculated by the number of user clicks received divided by the total number of impressions, and the results are generally presented in the form of a percentage.
