Internal Links

Internal links are hyperlinks that connect one page of a site to another on the same domain. They guide visitors through your content, help search engines discover pages, and pass ranking signals — often called link equity — from stronger pages to the ones you want to rank.

Three jobs internal links do

A single internal link works on three levels at once. It gives users a path to related content, it lets crawlers find and re-crawl pages, and its anchor text tells search engines what the destination is about. A link reading "winter tyre fitting guide" passes far more topical context than one reading "click here."

A structure that actually helps

Random cross-linking rarely moves rankings; deliberate structure does. The topic-cluster model works well: a comprehensive pillar page links down to every supporting article, and each supporting article links back up to the pillar and sideways to its siblings. This concentrates relevance around the pillar and helps it compete for the head term.

• Link new pages from established, well-crawled pages so they get discovered fast.
• Point a few links from high-authority pages at a page you're trying to lift.
• Use descriptive anchors, not "read more."
• Fix orphan pages — any page with zero internal links is nearly invisible.

Before and after

A blog with 40 posts and no structure had a buried "beginner's guide" stuck on page 3. Adding contextual links to it from the eight most-visited related posts — with varied, descriptive anchors — pushed it to position 4 within six weeks, no new backlinks required.

Internal linking is one of the highest-impact tasks in on-page SEO, and it's how you distribute link juice across a site.
