What is Internal Linking?
Internal linking is when you add clickable links on your website that take visitors to other pages on the same website. Think of it like creating a map that helps people (and Google) navigate your site more easily.
For example, if you write a blog post about "healthy breakfast ideas," you might link to another article on your site about "meal planning tips." That's an internal link.
Why does this matter? Internal links help search engines like Google understand which pages on your site are most important. They also help visitors find more helpful content, which keeps them on your site longer.
Why Internal Linking Matters for SEO
Internal links do three important jobs for your website:
1. They Help Google Find Your Pages
Google uses programs called "crawlers" that jump from link to link to discover content. If a page has no internal links pointing to it, Google might never find it. These hidden pages are called "orphan pages," and they won't show up in search results.
2. They Pass Along "Link Power"
Google gives each page a score based on how important it thinks that page is. When you link from one page to another, you're telling Google, "This page I'm linking to is valuable." This helps boost the linked page's chances of ranking higher in search results.
3. They Show Google What Your Site is About
When you link between related pages, you're creating topic groups that show Google you're an expert on that subject. For instance, if you have five articles about pizza recipes that all link to each other, Google understands your site is a good resource for pizza information.
How to Build an Internal Linking Strategy
The Hub and Spoke Model
Imagine a bicycle wheel. The center hub is your main guide or "pillar page" about a big topic. The spokes are smaller, specific articles that link back to that main page.
Example:
Hub: "Complete Guide to Digital Marketing"
Spoke 1: "Email Marketing for Beginners"
Spoke 2: "Social Media Tips"
Spoke 3: "SEO Basics"
Each spoke article links back to the hub, and the hub links out to all the spokes. This creates a strong topic cluster that tells Google you cover this subject thoroughly.
The Pyramid Structure
Think of your website like a pyramid:
Top: Your homepage
Middle: Main category pages
Bottom: Individual blog posts and product pages
Links should flow naturally from top to bottom and back up again. Your homepage should link to your main categories, those categories should link to specific articles, and those articles should link back up the pyramid.
Smart Anchor Text Rules
The clickable words you use for your links (called "anchor text") should describe what the linked page is about.
Good example: "Check out our guide on keyword research tools" ✓
Bad example: "Click here to learn more" ✗
Make your anchor text natural and descriptive, but don't stuff it with keywords or make it sound robotic.
Advanced Internal Linking Techniques for 2026
Using AI to Find Link Opportunities
New AI tools can scan your entire website and suggest where you should add internal links based on topic similarity. Instead of manually reading every article, these tools use "semantic search" to match related content automatically.
Insight: Companies using AI-powered linking strategies are finding 40% more internal linking opportunities than manual methods. The technology looks beyond just keywords to understand the actual meaning and context of your content.
Linking for Sales, Not Just Rankings
Most people only think about internal links for SEO, but they're also powerful for guiding visitors toward making a purchase or signing up.
Strategic approach: Create a linking path that matches the customer journey:
Awareness stage: Link from educational blog posts
Consideration stage: Link to comparison guides and case studies
Decision stage: Link to product pages and pricing
Fixing Keyword Cannibalization with Internal Links
Keyword cannibalization happens when you have multiple pages competing for the same search term. Instead of deleting pages, you can use internal links to tell Google which page is your "main" one.
Step-by-step fix:
Find pages targeting the same keyword
Choose your best, most comprehensive page as the primary
Add strong internal links from the other pages to your primary page
Update anchor text to reinforce the primary page's topic
Make sure the primary page doesn't link back to the competing pages
Insight: This method preserves your content while clearing up confusion for search engines. Many competitors only suggest redirects or removing pages, but internal linking offers a content-friendly solution.
How to Audit Your Internal Links
Step 1: Find Orphan Pages
Use a free tool like Google Search Console or a paid tool like Screaming Frog to identify pages with zero internal links. These pages are invisible to Google and need to be connected to your site structure.
Step 2: Check Your Click Depth
"Click depth" means how many clicks it takes to reach a page from your homepage. Important pages should be 2-3 clicks away maximum. If a valuable page is buried 7 clicks deep, visitors and Google won't find it easily.
Step 3: Look for Broken Internal Links
Broken links create dead ends that frustrate users and waste the "link power" you've built up. Regularly scan for 404 errors and fix them.
Step 4: Review Your Anchor Text
Make sure you're not using the same anchor text for every link. Variety looks more natural to Google. Also check that your anchor text accurately describes the destination page.
Internal Linking for Different Website Types
For Blogs
Link from new posts to older, related content. This keeps your archive active and helps Google recrawl older pages. Aim for 3-5 contextual links per article.
For E-commerce Sites
Use internal links in:
Product descriptions (link to related products)
Category pages (link to buying guides)
Blog content (link to product pages)
Insight: E-commerce sites often overlook blog-to-product linking. Strategic links from educational content to product pages can increase conversions by 15-25% according to recent studies.
For Service-Based Businesses
Connect your service pages to relevant case studies, testimonials, and FAQ pages. This builds trust and helps potential customers find the information they need to hire you.
Measuring Your Internal Linking Success
Track Position Changes in Google Search Console
After adding internal links to a page, note the date and watch its rankings over the next 4-8 weeks. Google Search Console will show you if the page is climbing in search results.
Monitor Click-Through Rates
If your internal linking strategy is working, you should see:
More pages per session (people clicking through to more content)
Lower bounce rates (fewer people leaving immediately)
Longer time on site
Use Link Score Metrics
Some SEO tools assign a "link score" showing how well-connected each page is. Pages with higher scores typically rank better because they receive more internal link equity.
Common Internal Linking Mistakes to Avoid
Too many links on one page: Keep it to 100-150 internal links maximum per page
Linking to irrelevant pages: Only link when it genuinely helps the reader
Using only sidebar/footer links: Contextual links within content are much more powerful
Forgetting about mobile navigation: Make sure your internal links work smoothly on phones
Never updating old content: Go back and add links from old articles to your new content
Accessibility and User Experience
Here's something most SEO guides ignore: internal linking affects how people with disabilities experience your website.
Key considerations:
Screen readers announce link text aloud, so "click here" doesn't tell blind users anything useful
Keyboard navigation relies on logical link structure
Color contrast matters for link visibility
Insight: Websites that optimize internal linking for accessibility see better engagement metrics across ALL users, not just those with disabilities. Clear navigation benefits everyone.

Final Thoughts
Internal linking is one of the easiest SEO strategies to implement yourself, and it costs nothing but time. Unlike getting backlinks from other websites (which is hard), you have complete control over your internal links.
Start small: pick one important page on your site and find five places to link to it from other relevant content. Track the results for a month. You'll likely see that page start climbing in search rankings.
The websites that dominate Google search results all have one thing in common: smart internal linking strategies that help both search engines and real people navigate their content. Now you have the knowledge to build the same advantage.
Frequently Asked Questions
How many internal links should each page have?
There's no perfect number, but most experts recommend 3-5 contextual links within your main content, plus navigation links. Avoid exceeding 150 total links per page, as this can dilute the value passed to each link.
Does internal linking directly improve keyword rankings?
Yes, but indirectly. Internal links help Google discover and understand your content, pass authority to important pages, and show topical relationships. Pages with strong internal linking typically rank higher than orphaned pages.
What's the difference between internal and external links?
Internal links connect pages on your own website (like different rooms in your house). External links point to other websites (like directions to your neighbor's house). Both are important for SEO, but you have full control over internal links.
How do I find internal linking opportunities on my site?
Start by listing your most important pages (pillar content, top products, key services). Then search your site for relevant keywords those pages target. Anywhere you mention those topics is a potential spot to add an internal link. AI tools can also automate this process.
Can too many internal links hurt my SEO?
Yes, if you go overboard. Hundreds of links on one page looks spammy to Google and confuses users. Focus on quality over quantity—link only when it genuinely helps your reader find related, useful information.
