Definition
Search volume is the estimated number of times a keyword or phrase is entered into a search engine within a specific timeframe, usually measured monthly. It helps businesses understand the level of demand or interest for a given topic. High search volume indicates strong interest but often comes with high competition, while lower volumes may reflect niche opportunities with less competition.
For example, the keyword best running shoes may have thousands of monthly searches, while lightweight trail running shoes for women may have fewer searches but attract a more targeted audience ready to buy.

Search volume data is collected and estimated through keyword research tools that analyze search engine logs, clickstream data, and third-party metrics. Different platforms such as Google Keyword Planner, SEMrush, and Ahrefs may show varying numbers due to different methodologies.
Advanced SEO and PPC strategies use search volume not as a standalone metric but in combination with keyword difficulty, cost per click, and intent. Seasonal trends also influence search volume, making it important to track how demand shifts over time. Segmenting by geography, device, or audience provides deeper insights into where and how often keywords are searched.

Example
