Internal linking connects one page of a website with another page on the same site. Navigation, article references, breadcrumbs and related-content sections can all form part of that structure.
The purpose is to create useful routes. A visitor should be able to move from an initial question towards the next relevant piece of information without having to restart their search.
Why do internal links matter?
Links help people discover content and understand relationships between pages. Crawlable links also help search engines find destinations within a website.
A page stored in the CMS may remain difficult to discover if nothing useful points to it. Publishing a URL and creating a navigable information resource are different tasks.
What is anchor text?
Anchor text is the linked wording a reader sees. It should help describe what following the link will provide.
“Read the installation requirements” gives more direction than an unexplained “click here”. Keep the wording natural and appropriate to the surrounding sentence.
Navigation versus contextual links
Navigation provides recurring routes across the site. Contextual links appear where another page expands on a subject within the content.
Both are useful. A service may belong in the main menu, while a specialist explanation is more helpful beside the question that makes it relevant.
How many links should a page contain?
There is no single count that suits every page. Add routes that help the reader and remove repetition that makes the page harder to follow.
A long glossary explanation may justify several related references. A short booking page may need fewer choices. The task should guide the decision.
How should related content be chosen?
Select a small number of genuinely useful next subjects. A metric definition might connect to its calculation, interpretation and improvement process.
Avoid assigning the same unrelated set of articles everywhere merely to populate a component. Editorial relevance makes the relationship meaningful.
What changes during a redesign?
Menus, folders and slugs can change. Update internal links to the intended destinations instead of relying indefinitely on redirects.
Check shared templates as well as individual pages. A single incorrect menu link can affect a large part of the site.
How do you review internal linking?
Identify important pages and inspect how someone can reach them. Follow the route from the homepage, relevant services and supporting content.
Then examine the links from those pages. The aim is a coherent journey with useful choices, not a dense network built solely to increase a tool's link count.

A practical example
Illustrative example: a glossary entry about cost per click links to conversion rate where it explains acquisition economics. A reader can understand the traffic price first and then explore what happens after the visit, without encountering an unrelated sales interruption.
Why it matters
Internal links turn separate pages into a usable information structure. They help readers continue learning and make important content easier to discover.
