What does CTR stand for in online advertising metrics?

Click-through rate, commonly abbreviated as CTR, is a metric that measures the effectiveness of an online advertising campaign by calculating the ratio of users who click on a specific ad to the total number of users who view that ad. CTR is expressed as a percentage, and it provides valuable insights into how compelling and relevant the ad is to the target audience.

Understanding CTR is essential in digital advertising because it helps advertisers assess the performance of their campaigns. A higher CTR indicates that the ad is successfully capturing user interest, leading to more clicks, whereas a lower CTR may prompt advertisers to reevaluate their targeting, ad copy, or creative strategies. In this context, CTR serves as a key performance indicator (KPI) that can guide optimization efforts for better engagement and higher conversion rates in advertising strategies.

The other options do not accurately describe CTR, as they pertain to different metrics or concepts within digital advertising.
