Internal linking is the practice of linking from one page on your website to another page on the same website. An internal linking strategy is a deliberate plan for those links, so that visitors can find what they need and search engines can understand which pages are most important and how your topics relate to each other. For most business websites, a few simple habits make a noticeable difference to how well key pages are discovered.
Unlike backlinks from other websites, internal links are entirely under your control. That makes them one of the most practical SEO improvements a business can make without outside help.
Why do internal links matter for SEO?
Internal links help search engines discover pages, understand what each page is about and judge which pages matter most. They also keep visitors moving towards the pages that turn them into enquiries.
Google finds most pages by following links. A page that no other page links to, known as an orphan page, may be found only through your sitemap, and Google has little context about where it fits. A page linked from your main navigation, related service pages and several relevant articles sends a much clearer signal.
The words used in the link, called anchor text, also give context. A link that says “industrial packaging solutions” tells both readers and Google more about the destination than a link that says “click here”.
For visitors, internal links answer the question “what next?”. Someone reading an article about choosing a water treatment system should be able to reach your water treatment service page in one click, not hunt for it through the menu.
What types of internal links does a website have?
Most websites have four kinds of internal links, and each plays a different role. A good strategy uses all of them rather than relying only on the menu.
| Link type | Where it appears | Main purpose | Common mistake |
|---|---|---|---|
| Navigation links | Header menu and footer | Reach core sections from anywhere | Menus with dozens of items that dilute focus |
| Contextual links | Inside the body text of pages and articles | Connect related topics with descriptive anchors | Vague anchors such as “read more” or “here” |
| Breadcrumbs | Above the page heading | Show where a page sits in the hierarchy | Breadcrumbs that do not match the real structure |
| Related content links | End of articles, product pages, sidebars | Suggest the next useful page | Automated lists that pick unrelated posts |
Contextual links usually carry the most meaning, because they sit within relevant text and use descriptive wording. They are also the type most business websites neglect.
How should you structure internal links on a business website?
Organise your site into clear topic groups, each led by a main page, and link related pages to that main page and to each other. Your most important commercial pages should be reachable within a few clicks of the home page.
Start with your money pages
Identify the pages that bring enquiries or sales: core service pages, main product categories and key location pages if you have them. These are the pages your internal links should support most. Every relevant article, case study or FAQ should point towards one of them.
Build topic clusters around them
A topic cluster is a main page, often called a hub or pillar page, surrounded by supporting pages on related subtopics. For example, a company offering WordPress services might have a main WordPress development page, supported by articles on speed, security and maintenance. Each article links to the main page, and the main page links out to the articles that answer common questions.
This blog follows the same idea: our guides on WordPress speed optimisation and WordPress security both connect to our WordPress development service.
Keep click depth shallow
Click depth is the number of clicks needed to reach a page from the home page. Important pages buried five or six clicks deep tend to be crawled less often and found less easily by visitors. Bring them closer through the menu, hub pages or links from popular content.
Connect related services and sections
Customers rarely need just one thing. Someone reading about website design may also need hosting advice, content help or SEO. Link related services to each other where the connection is genuine, so a visitor who lands on the “wrong” page can move to the right one without going back to the menu.
Consider a hypothetical engineering company with pages for CNC machining, sheet metal fabrication and powder coating. Many buyers need all three for one component. A short paragraph on each page explaining how the services work together, with a link to each, helps buyers see the full capability and helps Google see how the pages relate.
Online stores need the same thinking. Category pages should link to subcategories and top products, and product pages should link back to their category and to genuinely related items. Our guide to e-commerce category page SEO covers this in more detail.
Use your strongest pages to support new ones
Some pages already attract more visitors and links than others, often the home page, a popular guide or a long-standing service page. When you publish something new and important, add a relevant link to it from one of these established pages. It helps the new page get discovered and crawled sooner than it would through the sitemap alone.
How do you write good anchor text?
Use short, descriptive words that tell the reader what they will find on the other side. The anchor should fit naturally into the sentence and match the topic of the destination page.
- Be descriptive: “our guide to schema markup for small businesses” is better than “click here to read it”.
- Vary naturally: you do not need the exact same phrase every time. Different wording that clearly describes the page is fine and reads better.
- Avoid over-optimisation: forcing the exact target keyword into every anchor across the site looks unnatural. Our article on SEO practices to avoid covers this and similar shortcuts.
- Do not mislead: an anchor that promises pricing should lead to pricing information, not a generic contact page.
How do you find and fix internal linking problems?
Run a crawl of your site, look for orphan pages, broken links, redirect chains and important pages with very few internal links, then fix them in order of business importance.
Common problems to look for
- Orphan pages: pages that exist in the sitemap but receive no internal links. Either link to them from relevant pages or remove them if they serve no purpose.
- Broken internal links: links pointing to pages that return a 404 error. These waste visitors’ time and crawl attention. Update or remove them.
- Links through redirects: after a redesign or URL change, old internal links often point to redirected addresses. Update them to point directly at the final URL.
- Thinly linked key pages: important service pages that receive only a menu link. Add contextual links from related articles and pages.
- Nofollow on internal links: there is rarely a good reason to add nofollow to links within your own site. If a page should not be indexed, use a noindex tag instead.
Google Search Console’s Links report shows which of your pages have the most internal links, which is a quick way to see whether your priorities match reality. Our Google Search Console guide explains where to find it, and our technical SEO audit checklist covers crawling tools in more depth.
How many internal links should a page have?
There is no fixed number. Add a link wherever it genuinely helps the reader take the next step, and stop when further links would distract rather than help.
A detailed article of 1,500 words might naturally include five to ten contextual links. A short service page might include three or four, pointing to related services, a relevant case study or guide and the contact page. A page stuffed with links in every sentence becomes hard to read and makes each link less meaningful.
Clean URLs also make links easier to manage. Readable, stable addresses mean fewer broken links when content is reorganised; see our guide on SEO-friendly URL structure.
A simple internal linking routine
Internal linking is not a one-time task. Build these habits into how you publish:
- When publishing a new page, add at least two or three links to it from existing relevant pages, not just links from it.
- When publishing an article, link to the service page it supports.
- Every quarter, check for broken links and orphan pages.
- After any redesign or URL change, update internal links to the new addresses rather than relying on redirects.
