- Search intent
- The purpose behind a query—for example, learning, finding a specific site, comparing options or completing a task.
- Broad keyword

- Narrow keyword
- A more specific phrase that adds role, audience, problem or condition. It often points to a clearer content need.
- Search volume
- An estimate of how often a phrase was searched within a stated tool, place and time period. It is not a permanent or universal count.
- Competition
- A tool-specific estimate of how many pages or advertisers compete around a phrase. Different tools define it differently.
- CPC
- Cost per click: an advertising estimate, not a measure of educational importance or truth.
- SEO
