CTR (Click-Through Rate)

/ˌsiː.tiː.ˈɑːr/ noun

The percentage of users who click on your result after seeing it in search results. Calculated as clicks divided by impressions. In GSC, a low CTR despite high impressions typically signals a title or meta description mismatch with search intent. AI Overviews have reduced average CTR for top-ranking Google results by up to 58% as of 2026.
