# What is Click-Through Rate (CTR)? Examples with PlainSignal & GA4

**Click-Through Rate (CTR)** is a fundamental metric in digital analytics that quantifies the percentage of users who click on a link, ad, or call-to-action after seeing it. It illustrates how engaging and relevant your content or campaigns are to the target audience.

A high CTR typically signals effective messaging and design, whereas a low CTR highlights areas for improvement, such as copy, visuals, or targeting. CTR is essential across various channels—websites, email, paid search, and social media—providing a direct measure of user interest and campaign performance.
