SEO and AI search glossary

These are the terms used across the rest of the site, defined once and linked from wherever they appear. Rank tracking and AI search have collected a lot of vocabulary in a short time, and a good deal of it is three names for the same idea.

Where terms overlap, there is one canonical entry and the variants point at it, rather than a near duplicate page per synonym. Each definition says what the term measures, who measures it, and what it does not tell you.

Where a metric belongs to a specific vendor, the entry names the vendor. SERPs reports website authority from its own backlink data and does not calculate any vendor's branded authority score.
