Search Volume

Search volume is an estimate of how many times a keyword is searched in a period, usually a month, in one country or language. It comes from keyword tools that model the figure rather than count it, so it describes a string of words, not a set of people.

What the number is good for

Choosing between candidate pages. A phrase with volume can justify a page; a phrase with none may still carry demand that falls under the tool’s threshold or is spread across variants the tool cannot group. The number is most reliable for short, common queries and least reliable exactly where a small business competes: long, local, specific phrasings that each occur a handful of times.

Why it has no counterpart in AI answers

A question asked in conversation is one of many phrasings of the same need, and no assistant publishes counts for them. Google says its AI Overviews and AI Mode issue several related searches for one question, so a single query’s volume does not describe what gets retrieved for it either. The replacement this site uses is a panel of the questions customers of one trade in one place ask, put to one assistant, Claude with live web search, and asked again, on the same questions, once the fixes are live and every month with monitoring; the volume of a phrase is replaced by whether the business is named when the question is asked. The panel is described on the methodology page.

A common question

Does zero search volume mean nobody asks the question?

No. It means the tool’s model did not see enough exact-match searches to report a figure. The same need arrives at an assistant in dozens of phrasings, none of which the tool would count, and the assistant answers them all from the same pages.
