internal links and seo go hand in hand because internal links help search engines find your pages, understand what they are about, and decide which ones matter most. They also guide real people to the next useful step, which can improve engagement and conversions.

This guide explains what internal links do, how to build a sensible internal linking structure, and how to audit and improve what you already have. It is written for UK site owners, marketers, and content teams who want practical actions, not theory.

What internal links are and why they matter

An internal link is a link from one page on your website to another page on the same website. They sit in navigation menus, within blog posts, in footers, in sidebars, and in contextual content such as product guides.

Internal links matter for three main reasons:

• Crawling and discovery: Search engines follow links. If a page has no internal links pointing to it, it is easier to miss.
• Understanding: The words you use in the link and the surrounding text help explain what the destination page covers.
• Importance: Links signal which pages are central. Pages linked from many relevant pages often appear more important within your site.

How search engines use internal links

Search engines crawl the web by following links. On your site, internal links create pathways. A clear pathway helps bots reach deeper pages without wasting crawl time on dead ends, redirect chains, or repeated low value URLs.

Internal links and SEO also help with:

• Indexation: If a page is discoverable and provides value, it is more likely to be indexed and kept indexed.
• Context: A page linked from several related articles builds topical relevance. This is especially useful for content hubs.
• Canonical signals: Consistent internal linking to the preferred URL supports your canonical choice, for example linking to the clean version without tracking parameters.

Internal links and SEO: what actually moves the needle

Not every internal link change will shift rankings. The gains usually come from improving structure and relevance, not from adding dozens of links to every page.

1) Help key pages get found and prioritised

If you have pages that drive revenue or leads, they should not be buried. Link to them from places people and search engines naturally visit, such as:

• Top navigation and category pages
• High traffic blog posts
• Relevant guides and FAQs

2) Reduce orphan pages

An orphan page has no internal links pointing to it. Even if it is in your XML sitemap, it can still struggle to perform because it sits outside your site structure. Make a habit of checking for orphan pages after publishing new content.

3) Improve topical clusters

A strong approach is to build clusters: a central hub page that covers the main topic, supported by related pages that cover subtopics in detail. Link from the hub to the supporting pages, and link back where it makes sense.

Example cluster for a UK accountant:

• Hub: “Self Assessment tax return guide”
• Supporting: “Allowable expenses explained”, “Deadlines and penalties”, “How to register for Self Assessment”, “What to do if you missed a year”

4) Use internal links to shape journeys

Internal links are not only for bots. They help users move from information to action. A good pattern is:

• Informational page links to a comparison or checklist
• Checklist links to a service or product page
• Service page links to proof such as case studies, reviews, or accreditations

Types of internal links and when to use them

Navigation links

Menus and breadcrumbs set your core structure. Keep them stable and focused. If your menu has too many items, you dilute attention and make it harder to understand your priorities.

Contextual links within content

These are often the most valuable because they sit inside relevant text. They help both understanding and user flow. Add them where they genuinely help the reader take the next step.

Footer links

Footers are useful for essentials such as contact details, policies, and key categories. Avoid stuffing footers with dozens of keyword heavy links. Keep it tidy and user led.

Related content modules

“Related articles” or “You may also like” sections can work well if they are genuinely related and not random. If possible, base them on shared categories or tags, and keep the list short.

Anchor text: how to write it without overthinking

Anchor text is the clickable text in a link. Good anchor text is specific and natural. It should set expectations about what the user will see after clicking.

• Do: “See our guide to boiler servicing costs”
• Avoid: “Click here” or “Read more” with no context
• Do: Use partial matches and plain language
• Avoid: Repeating the exact same keyword anchor across many pages

A simple rule: write anchor text as if the link was removed and the sentence still needed to make sense. This will really help with your internal links and SEO.

Common internal linking problems (and how to fix them)

Broken internal links

Broken links waste crawl time and frustrate users. Fix them by updating the link to the correct URL or redirecting the old URL to the best replacement. Then update the internal links so they point directly to the final destination.

Redirect chains

If an internal link goes to a URL that redirects to another URL, you create unnecessary steps. Update internal links to point straight to the final URL. This is a quick win on large sites.

Too many links on a page

Long pages can naturally have more links, but if every other sentence contains a link, it becomes hard to read. Prioritise links that support the page’s purpose and remove the rest.

Pages competing with each other

If you have multiple pages targeting the same intent, internal links can make the confusion worse. Decide which page is the main one, strengthen it with internal links, and adjust other pages to support it. In some cases, merging content is the better option.

Orphaned or thin pages

If a page is thin and has no links, it is often a sign it should be improved, merged, or removed. Internal linking is not a substitute for useful content.

How to plan a sensible internal linking structure

A good structure is easy to explain. If you cannot describe how your site is organised in a few sentences, your users and search engines will struggle too.

Start with your main categories

For most UK business sites, categories map to services, product ranges, or locations. Keep categories broad enough to hold several pages, but not so broad that they become vague.

Create hub pages for important topics

A hub page is a strong overview that links to deeper pages. It can be a service hub, a buying guide, or a resource centre. The hub should answer the main questions and make it easy to navigate to specifics.

Link down and across where relevant

Link down from hubs to supporting pages. Link across between supporting pages when it helps the reader. Avoid linking across just to add links.

Use breadcrumbs where they fit

Breadcrumbs help users understand where they are, especially on ecommerce and large content sites. They also reinforce hierarchy.

Practical internal linking tips (step by step)

Step 1: List your priority pages

Choose 10 to 30 pages that matter most. For a UK business, this often includes:

• Core service pages
• Top product categories
• High converting landing pages
• Key guides that attract links and traffic

Step 2: Find pages that should link to them

For each priority page, identify 5 to 20 relevant pages that could link to it naturally. Look for:

• Blog posts on related questions
• FAQs that mention the topic
• Existing category pages
• Case studies that demonstrate the service

Step 3: Add contextual links where they help the reader

Place links in sections where the reader would logically want more detail or the next step. Keep the surrounding sentence helpful. Aim for clarity over cleverness.

Step 4: Improve your hub pages

If you have a hub page that is meant to be central, make sure it:

• Links to all key supporting pages
• Uses clear headings and short sections
• Includes a short “next steps” section with links to actions

Step 5: Fix technical issues in bulk

Run a crawl of your site using an SEO crawler and export reports for:

• 4xx internal errors
• 3xx internal redirects
• Orphan pages (if your tool supports it)
• Pages with very few internal links

Step 6: Set a simple publishing checklist

Every time you publish a new page, do this before it goes live:

• Add at least 2 to 5 internal links from relevant existing pages to the new page
• Add 2 to 5 links from the new page to helpful related pages
• Check the page is reachable from a sensible category or hub
• Confirm the URL is correct and consistent with your structure

Examples of internal linking that work well

Ecommerce example

A UK skincare shop has a category page for “Vitamin C serums”. A helpful internal linking setup could be:

• Category page links to a guide: “How to choose a Vitamin C serum”
• Guide links back to the category and to specific product pages as examples
• Each product page links to related categories such as “SPF” and “Moisturisers”
• Blog posts about dull skin link to the guide and category

Local service example

A Manchester plumber has service pages and advice content:

• Advice post: “What to do if your boiler pressure drops” links to “Boiler repair in Manchester”
• Service page links to proof: “Recent boiler repair jobs” and “Customer reviews”
• Location pages link back to the main service hub to avoid duplication

FAQ: internal linking

How many internal links should a page have?

There is no perfect number. Add links where they help the reader and support the page’s purpose. Focus on relevance and clarity rather than hitting a target.

Do internal links need to be dofollow?

Most internal links should be standard links. Use nofollow internally only when you have a clear reason, such as user generated content areas you cannot vouch for.

What is an orphan page and why is it bad?

An orphan page has no internal links pointing to it. It can be hard for search engines and users to find, which often limits traffic and rankings.

Should I link to the same page multiple times from one article?

Usually once is enough if it is placed well. A second link can make sense on long pages, but avoid repeating links in a way that distracts from reading.

Are breadcrumbs good for SEO?

Breadcrumbs can help users navigate and reinforce your site hierarchy. They are most useful on larger sites with clear categories.

How do I find internal linking opportunities quickly?

Start with your highest traffic pages and add links to relevant priority pages. You can also search your site for mentions of a topic and turn those mentions into contextual links.
