What is Click-Through Rate (CTR)?
Click-through rate is the ratio of clicks to impressions for a given search result, expressed as a percentage. If a page receives 200 impressions in Google Search and 10 clicks, its CTR is 5 percent. CTR is reported at both the page and query level in Google Search Console.
Why it matters
CTR indicates how compelling your title tags and meta descriptions are relative to competing results, and improvements here can drive meaningful traffic increases without ranking changes.
