It stands for "Click-Through Rate," which indicates the percentage of users who click on a specific ad compared to the total number of users who view it. A higher CTR suggests that the ad is engaging and relevant to the audience. Advertisers often analyze Ruf CTR to optimize their campaigns and improve performance. By understanding which ads generate more clicks, marketers can adjust their strategies, such as changing ad copy or targeting different demographics, to enhance overall engagement and conversion rates.
