Search Volume
In one line
Search volume is the average number of times a keyword is searched in a given period — usually per month — and it's one of the basic inputs for prioritising SEO opportunities.
Going deeper
Search volume is most often expressed as MSV (Monthly Search Volume). Tools like Google Keyword Planner, Ahrefs and Semrush estimate it from clickstream data, and the numbers vary by tool — use them comparatively rather than as absolutes.
In practice, you rarely look at volume alone. It only makes sense alongside keyword difficulty, intent and conversion potential. A 200-volume transactional term frequently beats a 5,000-volume informational one for revenue.
One emerging nuance: as users shift queries to ChatGPT or Perplexity, raw search volume can drop while the underlying business value holds steady or rises. Don't read declining volume as a dead topic.
