Anchor text is the visible, clickable wording of a hyperlink that helps people and search engines understand the destination’s subject.
Meaning and scope
Anchor text is the visible, clickable wording inside a hyperlink. In <a href="/glossary/sitemap-xml">XML sitemap guidance</a>, the words “XML sitemap guidance” are the anchor text. It serves people first: a reader should be able to predict the next page without opening it. Search engines can also use linked wording and the surrounding context to interpret a destination, but it is only one signal among many.
The term applies to internal and external links, although the editor controls them differently. Internal anchors are part of a site’s information architecture. External anchors are written by other publishers, so a site owner can observe them but cannot safely prescribe a “target ratio” for them. Google’s public guidance asks for descriptive, concise link text and warns against manipulative link schemes; it does not publish a safe percentage for exact-match anchors.
Writing useful anchor text
Start with the destination’s job. A link to a troubleshooting page can say “check the rendered canonical tag”; a link to a glossary entry can say “how XML sitemaps declare canonical URLs”. The label should distinguish the target from nearby links. “Read more”, a bare URL, and a repeated menu label can be acceptable in a constrained interface, but they provide little context when used as the main in-content link.
- Descriptive
- Names the destination topic or action in the sentence’s natural language.
- Concise
- Uses the shortest phrase that keeps the meaning; it does not turn a sentence into a keyword list.
- Accurate
- Matches the destination’s visible purpose, not a hoped-for query.
- Crawlable
- Uses a standard
<a href>link to the final public URL when the link should be discovered.
For images used as links, the accessible name needs the same care. A meaningful alt value can provide the link’s text alternative; decorative linked imagery may need an explicit text label elsewhere. Do not duplicate a long caption and an equally long alt attribute just to repeat terms.
Navigation exposes another boundary. A short navigation label may be the clearest available description because space is limited, while an editorial link in an explanatory paragraph can be more specific. Evaluate each pattern in its interface and task. Do not force every occurrence to contain a query phrase when a product category, account section or help topic has a clearer established name.
A practical review
Review anchors page by page, not as a hunt for a global percentage. Export or crawl the internal links, group them by destination, then read a sample in the source-page sentence. Mark three kinds of mismatch: text that promises a different destination, many links that use indistinguishable generic labels, and links that point through redirects rather than to the canonical URL.
- Choose an important destination and state what a reader should find there.
- List internal links to it with source URL, visible text, surrounding sentence and final resolved target.
- Replace misleading or duplicated labels where the sentence can carry a clearer description.
- Check that the final route is crawlable and does not add a locale prefix, redirect hop or irrelevant parameter.
- Re-crawl after the change and keep the before/after export so the review is reproducible.
Limits and common mistakes
Do not write anchors as if they were keywords to distribute mechanically. Repeating the same commercial phrase in navigation, footers and editorial copy can make the experience less clear and can create a pattern that is hard to justify. A good alternative is not arbitrary variation: it is wording that explains the specific reason for each link.
Do not ask partners to place paid or exchanged links with keyword-heavy anchors. Paid placements need the appropriate rel value such as sponsored or nofollow under Google’s guidance, and link exchanges intended primarily to manipulate rankings fall under link-spam policy. The useful editorial question is whether the link gives a reader a relevant, honest next step.
Finally, separate accessibility and SEO checks. Link text can be understandable while the destination is blocked, redirected or missing; a technically crawlable link can still be vague to a reader. Inspect both the rendered text and the resolved HTTP destination.
