It is a metric which shows how many clicks your online ads receive on an online platform or a Search Engine Result Page for a certain duration of time. Click-Through-Rate is calculated by dividing the number of clicks with the number of times of the ad or search result has been seen. This calculation will help you to understand whether the ad titles and messages match the interests of the web visitors or not. A higher Click-Through-Rate indicates more engagement and it takes an important role to increase the conversion rate.
