What Is Anchor Text?

Anchor text is the visible, clickable wording of a hyperlink — the words between the <a> tags. Engines have always read it as a relevance hint: the anchor describes what the linking page believes the destination is about, which makes it one of the few signals written by the linker rather than the linked.

Why anchors matter to machine readers

For a crawler, an anchor is a labeled edge in a graph: "this page relates to that page, and the relationship is called X." Multiply that across a site and anchors collectively sketch an entity map — which terms are synonyms, which concepts are parents and children, which pages define what. Retrieval-augmented engines benefit the same way: descriptive anchors give the fetched HTML self-explanatory context, whereas a paragraph full of "read more" links strips it. Screen-reader users, who often navigate by tabbing between links, get the identical benefit — accessibility and machine legibility converge here.

Descriptive-linking practices

• Name the destination's subject: "schema.org's DefinedTerm type," not "this page."
• Use the term's canonical name in glossary cross-links — consistent anchors across a library reinforce which page is the definition of record.
• Keep anchors short but complete — a noun phrase, not a full sentence, not a lone "here."
• Match anchor to heading — when the anchor echoes the destination's H1, every system reading the pair gets a coherent signal.
• Vary external anchors naturally — brand names, partial matches, and plain descriptions; uniform exact-match commercial anchors have been a spam fingerprint since Penguin in 2012.

Example

An API company audited its docs and found 1,400 instances of "see here" anchors. Rewriting them to descriptive noun phrases ("rate limit headers," "OAuth token refresh flow") produced a measurable side effect beyond UX: AI assistants answering questions about the product began linking the correct deep pages more often, because retrieval could finally tell the destinations apart. The internal linking graph existed before; the labels made it legible.
