✍️ Introduction
Internal linking is one of the most important — and often overlooked — parts of SEO.
An internal link connects one page of your website to another page on the same domain. When implemented strategically, internal links can help users discover relevant content, help search engines understand your website structure, and direct attention toward important pages.
A strong internal linking strategy is not about adding as many links as possible.
It’s about creating a logical network of relevant pages that helps both users and search engines understand your website.
🔍 SEO Problem
Many websites have valuable content but lack a clear internal linking structure.
Common problems include:
- Important pages have very few internal links
- Blog posts are not connected to relevant service pages
- Internal links point to irrelevant pages
- Too many links are concentrated on a few pages
- Important pages are several clicks away from the homepage
- Anchor text is vague or repetitive
- Orphan pages exist without meaningful internal links
- Old content is not connected to newer content
- Internal links point to redirected or broken URLs
These issues can make your website harder to navigate and can weaken the relationship between related topics.

💡 Why It Happens
Internal linking problems usually happen because websites are built page-by-page instead of being planned as a connected information structure.
For example, imagine a website has:
SEO Services → Technical SEO → Technical SEO Audit → Crawlability → Indexing
If these pages are not properly connected, users and search engines may have difficulty understanding how the topics relate to each other.
A well-planned internal linking structure creates clear relationships between:
Pillar Pages → Supporting Content → Related Subtopics
This can also help distribute internal authority throughout the site and make important content easier to discover.
🛠️ How to Build a Strong Internal Linking Structure
1. 🏗️ Create Topic Clusters
Organise your content around major topics.
For example:
Pillar Page: Technical SEO
Supporting Pages:
- Technical SEO Audit
- Crawlability
- Indexing
- XML Sitemap
- Robots.txt
- Canonical Tags
- Core Web Vitals
Connect the supporting pages to the pillar page and link relevant supporting pages to each other's specialising.

2. 🎯 Link From High-Authority Pages
Find pages on your website that already have strong backlinks, traffic, or organic visibility.
Use relevant opportunities on those pages to link to important pages that need more visibility.
3. 🔗 Use Relevant Anchor Text
Avoid generic anchor text such as:
❌ “Click here” ❌ “Read more” ❌ “Learn more”
Instead, use descriptive anchor text that naturally explains the destination.
For example:
✅ “technical SEO audit” ✅ “XML sitemap optimisation” ✅ “local SEO strategy”
Get ABU AHAD’s stories in your inbox
Join Medium for free to get updates from this writer.
Keep anchor text natural and useful for the reader.
4. 🚨 Find Orphan Pages
An orphan page has few or no internal links pointing to it from other relevant pages.
Use a site crawler to identify pages that aren’t properly connected to the rest of your website.
Then add relevant internal links where they genuinely help users.
5. 📊 Prioritise Important Pages
Not every page deserves the same internal linking attention.
Prioritise pages that contribute directly to your business goals, such as:
- Service pages
- Product pages
- High-value landing pages
- Important category pages
- Key informational resources
6. 🔄 Update Older Content
When publishing a new article, don’t only link to the new article.
Go back to relevant older articles and add links to the new content where appropriate.
This creates a stronger and more connected content ecosystem.
7. 🧭 Keep Important Pages Accessible
Try to avoid making important pages unnecessarily difficult to reach through your site’s internal navigation.
Your website should have a logical hierarchy that users can understand.
8. 🛠️ Fix Broken Internal Links
Regularly identify internal links leading to:
- 404 pages
- Redirect chains
- Incorrect URLs
- Deleted content
Replace them with the correct, relevant destination whenever possible.
9. 🔍 Review Internal Links During Content Audits
Internal linking should not be a one-time task.
Whenever you update or audit content, check:
Can this page link to another relevant page?
And:
Are other relevant pages linking back to this page?
10. 🤖 Think About Users First
Don’t add internal links simply because you want more links.
Every internal link should have a purpose.
Ask:
“Will this link help the visitor understand the topic or take the next useful step?”
If the answer is yes, the link is probably worth considering.
📈 Example of a Strong Internal Linking Structure
A simple SEO content structure could look like this:
SEO Services ↓ Technical SEO ↓ Technical SEO Audit ↓ Crawlability & Indexing ↓ XML Sitemap ↓ Robots.txt
Then connect closely related pages horizontally:
Crawlability ↔ Indexing ↔ Sitemap ↔ Robots.txt
This creates a logical topic network instead of isolated pages.
✅ Action Checklist
☐ Identify your main pillar pages. ☐ Group related content into topic clusters ☐ Find orphan pages ☐ Identify high-authority pages ☐ Add relevant links to important pages ☐ Use descriptive anchor text. ☐ Link older content to newer relevant content ☐ Fix broken internal links ☐ Remove unnecessary redirecting internal links. ☐ Review important pages’ click depth ☐ Connect related supporting articles ☐ Audit internal links regularly. ☐ Prioritise user usefulness over link quantity
📌 Key Takeaway
A strong internal linking structure turns individual pages into a connected SEO ecosystem.
Don’t think of internal links as simple navigation links.
Think of them as a way to communicate:
Which pages are important? Which topics are related? How is your website’s information organised?
A strategic internal linking structure can make your website easier to navigate, easier to crawl, and easier to understand.
