What is internal linking?

Links are how search engines discover pages and how they infer which pages matter and what they are about. A page with no internal links pointing to it is hard to find; a page that many relevant pages link to, with clear anchor text, is easy to find and easy to understand.

Good internal linking is contextual: the link sits where a reader would want the next page, and the anchor text says what that page is. This site adds most of its in-article links from a curated map of phrases, under a few fixed rules. When two phrases overlap, the longest one wins, so "llms.txt generator" links to the free tool rather than to the article about llms.txt. Each phrase links at most once per article, and no page gets more than one link from the same article. An ordinary article gets at most eight of these links, plus up to three to glossary definitions, so none is over-linked. An article never links to itself.
