Internal Linking Strategy: The Free SEO Boost You're Ignoring

← Back to all posts

Internal links are links from one page on your website to another page on your website. They're completely under your control, they cost nothing, and they directly affect how Google understands and ranks your pages.

Yet most small business websites barely use them.

Why Internal Links Matter

1. They Tell Google What's Important

Google follows links to discover and understand pages. Pages with many internal links pointing to them are seen as more important than pages with few. If your most important service page has only one link (from the navigation menu), you're telling Google it's no more important than your privacy policy.

2. They Distribute Authority

When one of your pages earns a backlink from an external site, that authority can flow to other pages through internal links. Good internal linking spreads the benefit of every backlink across your site.

3. They Help Users

Internal links keep visitors on your site longer by guiding them to related content. Someone reading about "how to choose a plumber" should see a link to your plumbing services page. That's good UX and good SEO.

4. They Help Google Understand Context

The text you use for an internal link (anchor text) tells Google what the linked page is about. "Click here" tells Google nothing. "emergency plumbing services in Leeds" tells Google exactly what that page covers.

The Internal Linking Checklist

Structure Links (Every Site Needs These)

[ ] Homepage links to all main category/service pages

[ ] Every page is reachable within 3-4 clicks from the homepage

[ ] Breadcrumb navigation present on all pages (with BreadcrumbList schema)

[ ] Footer links to key pages (services, location, contact)

[ ] No orphan pages (every page has at least one link to it)

Content Links (Blog + Service Pages)

[ ] Every blog post links to at least 1-2 relevant service pages

[ ] Service pages link to related blog content ("Learn more about [topic]")

[ ] Blog posts link to related blog posts

[ ] Pillar pages link to all their cluster posts (and vice versa)

[ ] "Related posts" section at the bottom of each blog post

Anchor Text Rules

Do: Use descriptive anchor text that includes relevant keywords

- Good: "our [emergency plumbing service](/services/emergency)" - Good: "learn about [Core Web Vitals](/blog/core-web-vitals)"

Don't: Use generic text

- Bad: "[Click here](/services/emergency) for more info" - Bad: "Read more [here](/blog/core-web-vitals)"

Don't: Over-optimise (using the exact same keyword every time looks spammy)

The Hub and Spoke Model

The most effective internal linking structure for content:

Hub (Pillar Page): A comprehensive guide on a broad topic

Links OUT to every related spoke/cluster post

Receives links IN from every spoke/cluster post

Spokes (Cluster Posts): Focused posts on specific sub-topics

Links TO the hub/pillar page

Links to 1-2 other relevant spokes

Example:

Hub: "The Complete Guide to Local SEO"

Spoke 1: "How to Set Up Google Business Profile" (links to hub)

Spoke 2: "How to Get More Google Reviews" (links to hub + spoke 1)

Spoke 3: "What Is NAP Consistency?" (links to hub + spoke 2)

This structure tells Google that your hub is the authoritative page on the topic, supported by detailed sub-topic content.

Quick Audit: Check Your Internal Links

1. Open your most important service page 2. Count how many other pages on your site link to it 3. If the answer is "just the navigation menu" -- you have work to do 4. Check your 5 most recent blog posts: do they link to any service pages? 5. If not -- add relevant links today

Common Internal Linking Mistakes

1. Only using navigation links. Menu links are important but they're the same on every page. Contextual links within content are more powerful. 2. Linking to the homepage excessively. Your homepage already gets the most links. Link to deeper pages that need the authority. 3. Forgetting to update old content. When you publish a new service page, go back and add links to it from relevant existing posts. 4. Using the same anchor text every time. Vary your anchor text naturally. Multiple links saying "plumber in Leeds" looks manipulative. 5. Having orphan pages. If Google can only find a page through your sitemap (not through any internal link), it's likely seen as low-importance.
