An internal linking strategy is a deliberate plan for how pages on your own website link to each other. Done well, it helps visitors find what they need, helps Google discover and understand your pages, and points attention towards the pages that earn you business.
It is one of the few SEO levers fully in your control. No one else has to agree to link to you. The catch is that it needs thought: random links added to hit a number do very little, while a clear structure supports everything else you do in SEO.
What internal links actually do
Internal links do three jobs at once.
- Discovery. Search engines find pages by following links. A page with no links pointing to it may never be found or may be treated as unimportant.
- Context. The words used in a link, and the page it comes from, tell Google what the destination is about and how it relates to other pages.
- Priority. Pages that receive many relevant links from across your site tend to be seen as more important than pages that receive few.
They also serve people. A link from a helpful article to the relevant service page is simply a good way to guide a reader who is ready for the next step.
Start with structure, not with links
Before you add a single link, decide what your site is for. Which ten or twenty pages must perform? For most business sites these are the main service or product pages, key category pages and the contact or enquiry page. Everything else exists to support them.
A sensible structure usually looks like this: the homepage links to main service or category pages, those link to more specific pages beneath them, and supporting articles link back up to the relevant service. Every important page should be reachable in a few clicks from the homepage. Our guide to SEO friendly website design explains how to plan this at the design stage, when it is cheapest to get right.
Group related content together
Think in clusters. A dental clinic might have a main page on implants, supported by pages on the procedure, recovery, suitability and costs. Each supporting page links to the main one, and the main one links out to them. The cluster tells Google that you cover the subject in depth and makes it clear which page is the lead.
Writing anchor text that helps
Anchor text is the clickable wording. Descriptive anchors help both readers and search engines. Vague ones waste the opportunity.
- Good: 'our guide to choosing a Google Ads agency'. It tells the reader what to expect.
- Weak: 'click here' or 'read more'. It says nothing about the destination.
- Risky: the same exact-match keyword phrase used on every link to a page. It reads as forced.
Vary your wording naturally, the way you would when speaking, and let the surrounding sentence give context. The link should read like part of the sentence, not like something stuck on.
Where to place links
Links within the main body of a page, surrounded by relevant text, generally carry more meaning than links in a footer or sidebar. Navigation menus and footers are still useful for users and for core pages, but they should not be your only method of linking.
Consider these placements:
- In-article links to related guides and to the relevant service page.
- Breadcrumbs, which show where a page sits in the structure.
- Related-content sections at the end of articles, chosen by relevance rather than recency.
- Links from high-traffic pages to pages you want to grow.
Put the most valuable links where people are likely to see them. A link buried at the bottom of a long page is less useful than one placed where a reader naturally asks the next question.
Find and fix the common problems
Most business websites we review share the same handful of problems.
- Orphan pages. Pages with no internal links pointing to them. Google may not find them, and visitors certainly will not.
- Important pages buried deep. A key service page that takes five clicks to reach is telling Google it is unimportant.
- Broken links. Links to deleted or moved pages waste visitors' time and can pass crawlers to error pages.
- Links through redirects. After a redesign, many links still point to old URLs that redirect. Update them to the final address.
- Everything links to the homepage. Heavy linking to the homepage and contact page, with little going to services, concentrates attention in the wrong place.
- Competing links. Several pages linking with the same anchor to different targets, which can contribute to keyword cannibalization.
A crawl using a tool such as Screaming Frog or the site audit in any major SEO platform will list orphan pages, depth and broken links quickly. Interpreting the results is the harder part: not every orphan page needs a link, and not every deep page is a problem.
Examples from real business types
For an ecommerce store, category pages should link to their best products and to buying guides, and product pages should link back to their category and to related products. A shopper reading a guide on choosing a mattress should have a clear path to the mattress category.
For a B2B manufacturer, product pages benefit from links to application pages, case descriptions and technical explainers, and those supporting pages should link back to the relevant product. For a service business with several locations, each location page should link to the services offered there, and each service page should link to the locations that offer it, with genuinely different information on each.
In each case, the test is the same: does the link make sense for someone trying to make a decision?
How many links are too many?
There is no magic number. Google has said it can follow a large number of links on a page. The practical limit is usefulness. If a page has so many links that none stands out, readers will ignore them all. A 1,500 word article with a handful of relevant links reads well. The same article with fifty links looks spammy.
Ask of every link: would a reader of this page genuinely want to go there next? If yes, keep it. If it is there only to push a keyword, remove it.
A routine you can maintain
Internal linking is not a one-off project. Every new page needs links in and links out, and old pages need updating when something more relevant appears.
- When publishing a page, link to it from at least two or three relevant existing pages.
- Link from the new page to its parent or related service.
- Once a quarter, review the pages that earn you enquiries and check they receive links from relevant content.
- After any redesign or migration, check that internal links point to final URLs.
Where a CMS such as WordPress is in use, plugins can suggest links, but treat suggestions as prompts, not decisions. They do not understand your business priorities. If your site needs a bigger rebuild before any of this works, website redesign is the right starting point.
