Click-Through Rate (CTR) in Google Analytics measures the percentage of users who click on a link, ad, or other clickable element compared to the total number of users who view it. It is calculated by dividing the number of clicks by the number of impressions and multiplying by 100. CTR helps assess the effectiveness of online campaigns, content, or ads in engaging users. https://itechsole.com/powerful-tips-to-effectively-optimize-google-analytics-ctr/
