Internal Linking Strategy: How to Build SEO Authority Across Your Website

Short answer: internal links help Google discover your pages and understand how they relate, and they guide visitors to the next useful page. Google’s guidance is simple: make every important page reachable through a normal link, and write link text that describes the destination. Beyond that, link structure is a design choice, not a formula. Last reviewed: 23 October 2026.

At 5D we plan internal links as part of the content structure. Explore our digital marketing services or the SEO Starter Package.

What Google says about links

  • Use crawlable links. Google generally follows links that are <a> elements with an href attribute. Links built only with scripts or without an href may not be followed.
  • Describe the destination. Anchor text should be descriptive, reasonably concise and relevant to the linked page. Google suggests reading the anchor on its own and checking it makes sense. Avoid “click here” and keyword stuffing.
  • Link every important page. Google advises that every page you care about should have a link from at least one other page on your site.
  • Links are how Google finds pages. Its starter guide says the vast majority of new pages it finds each day are found through links.

Google does not publish an ideal number of links per page or a “link depth” rule, and it does not describe anchor-text ratios as a factor. The advice below is our practice, not Google policy.

How to build an internal linking structure

1. Map your pages by role

Separate pages into three roles: main topic pages (the services or guides you most want to rank), supporting articles that cover sub-questions, and commercial pages (services, products, contact). Decide which supporting pages should lead to which commercial page.

2. Build topic clusters

Link the main topic page to its supporting articles, and link those articles back to it and to each other where relevant. This gives readers a path and gives Google clear context about what each page covers. Our view: this works because it mirrors how people research a topic, not because of a hidden ranking mechanism.

3. Write useful anchor text

Use natural phrases that tell the reader what they will find, such as “technical SEO audit checklist“. Vary wording naturally instead of forcing an exact keyword every time.

4. Send readers to the right commercial page

Link from guides to the service or product that genuinely solves the problem described, and make sure that page is current and fast. If you run paid campaigns such as Google Ads, use the same pages as landing destinations.

5. Find and fix orphan pages

Compare your sitemap with a crawl to find pages with no internal links, then link them from relevant pages or remove them if they have no purpose. Keep important pages within a few clicks of the home page, which is a usability goal that also helps discovery.

6. Maintain the links

When you publish a new article, add links to it from two or three related older pages. When you change or retire a URL, update links and add a 301 redirect. Check for broken links regularly; our on-page SEO guide covers the rest of the page-level work.

Common mistakes

  • Navigation or buttons that are not real links
  • Generic anchors (“read more”, “click here”) for important pages
  • Dozens of links packed together without context
  • Linking to a different page for the same topic from every article, which splits the signal about which page is the main one
  • Leaving links to redirected or deleted pages

Clear, consistent connections between pages help readers and search systems understand what your site is about. Google says AI features need no special optimization beyond the usual guidance. See how AI search is changing SEO.

Conclusion

Good internal linking is mostly editorial discipline: link related pages, describe them honestly, and keep the structure tidy as the site grows. It cannot guarantee a ranking, but it makes sure your best pages are found and understood.
