Internal linking is the SEO tactic most businesses completely neglect. It's not sexy. There's no $500/month tool to buy. But it works, and you can do it yourself in an afternoon.
Here's the thing: every link you add is a choice about which pages matter most on your site. Google notices. Your visitors notice. Get it right and you win on both fronts.
What Internal Links Actually Do
An internal link is just a clickable link from one page on your site to another page on your site. It sounds simple because it is. But the effects are powerful. (For more on this, check out our guide on our on-page SEO checklist.)
They help Google crawl your site. Google crawls by following links. If a page has no links pointing to it, Google might miss it entirely. Internal links create pathways. More pathways = more complete crawling.
They distribute authority. When you link to a page, you're essentially telling Google "this page matters." If important pages on your site link to a specific page, that page gains authority. You can use this strategically to push ranking power to your money pages.
They improve user experience. Good internal links guide visitors to related content they actually want. A visitor lands on your services page and sees related articles? They might click through and spend more time on your site. Google sees longer sessions and counts that as a positive signal. We cover this in more detail in our post about our beginner's guide to SEO.
They reduce bounce rate. A page with no internal links is a dead end. A page with thoughtful internal links to related content keeps people engaged.

The Simple Framework: Hub and Spoke
You don't need to overthink this. Use the hub and spoke model.
Hub pages are your main topic pages. For a yoga studio, that might be "yoga classes," "meditation," "pricing." For a consulting firm, it's "services," "case studies," "about us." These are pages you actually want to rank.
Spoke pages are supporting content—blog posts, detailed guides, FAQs. These provide depth and authority to your hub.
Here's the structure:
-
Hub pages link to spoke pages. Your main "Services" page links out to blog posts about specific services.
-
Spoke pages link back to hub pages. A blog post about "beginner yoga" links back to your "yoga classes" page.
-
Spokes link to related spokes. Blog posts link to related blog posts (but not excessively).
-
All important pages are linked from your homepage or main navigation. No page should be more than 3 clicks away from your homepage.
Best Practices for Internal Linking
Use descriptive anchor text. Don't link with "click here" or "read more." Use anchor text that actually describes where you're linking. "Learn about our SEO services" is better than "services." Google reads the anchor text and it helps rank both pages.
Link to pages that matter. Don't link to every page equally. Your important pages (services, main offerings, key conversions) should have more internal links pointing at them.
Use relevant links. If you're writing about content marketing strategy, link to your content marketing services page. Don't randomly link to your pricing page just because. Relevance matters.
Don't overdo it. 2-4 internal links per 1,000 words of content is plenty. Over-linking looks spammy and confuses readers. Quality over quantity.
Keep links in the body content. Links in your header, footer, and sidebar are okay, but the real juice comes from links within your actual content. Those are what Google values most.
Update existing content. You don't need to write new content to benefit from internal linking. Go back to your old blog posts and add links to newer content or your main service pages. This is quick, free, and works.
Common Mistakes to Avoid
Linking with "click here" or "more info." These anchor texts tell Google nothing. Use specificity.
Linking to unrelated pages. A blog post about email marketing shouldn't link to your pricing page just to boost traffic. Google gets suspicious of unnatural linking patterns.
Ignoring your important pages. If you have a page you want to rank but it gets zero internal links, you're handicapping it. Make sure your money pages have links pointing to them.
Creating orphan pages. A page with no internal links is invisible to Google and users. If you wrote it, link to it.
Excessive linking. Don't turn your blog post into a hyperlink farm. 3-4 relevant internal links per post is the sweet spot.
Forgetting about sitemap and navigation. Your sitemap and main navigation should link to all important pages. This is foundational.
A Concrete Example
Let's say you run a digital marketing agency. Here's how you'd structure internal linking:
Your homepage links to your main service pages: "SEO services," "paid ads," "social media."
Your "SEO Services" page (hub) has links to blog posts: "how to rank your site," "technical SEO checklist," "keyword research guide."
Those blog posts (spokes) link back to your "SEO Services" page with descriptive anchor text: "learn more about our SEO strategy."
Related blog posts link to each other: "keyword research" post links to "technical SEO" post.
Every blog post links from your main navigation, so Google can find them.
The result? Your service pages are discovered easily. They gain authority from blog content. Visitors move through your site. Google sees a clear structure. Everyone wins.
The 30-Minute Audit You Should Do Today
Open your main service pages or money pages. Use the browser's "Ctrl+F" to search for outbound links. Do these pages link to enough supporting content? Add 2-3 links if they don't.
Now audit your blog. Do older posts link to your main offerings? If not, add links. This is fast, high-value work.
Finally, check your sitemap. Are all important pages listed? They should be.
That's it. You've improved your internal linking structure in 30 minutes without hiring anyone.
Why This Matters for Your Business
Internal linking is one of the few SEO tactics you fully control. You don't need a third-party site to link to you. You don't need Google to change their algorithm. You just need to use the content you already have and connect it thoughtfully.
It compounds over time. A well-structured site with 50 blog posts and clear internal linking patterns is worth more than 50 disconnected blog posts with no links between them.
Good internal linking is the foundation. But if you want to audit your entire site and create a visibility strategy, talk to us. We'll tell you exactly what's working and what needs fixing.
