Internal linking
Internal linking is the network of links connecting pages within a single site. It distributes authority across pages, guides crawlers through the structure, and shortens the path for users looking for specific information.
In practice
The governing rule: no important page more than three clicks from the homepage. On sites our engine generates, each city page links to its real neighboring municipalities — distances computed, not guessed — and each service page links to related services. A well-designed internal link structure frequently outperforms ten average external links for a given page.
