Introduction
Every page on your website should help visitors discover another useful page.
This is exactly what internal linking achieves.
Internal links connect related pages across your website, helping users navigate naturally while also helping search engines understand your content structure.
A strong internal linking strategy improves user experience, distributes authority across your website, and strengthens your overall SEO.
Quick Answer
An internal link is a hyperlink that points from one page on your website to another page on the same website.
Unlike backlinks, which come from external websites, internal links remain entirely under your control.
Why Internal Linking Matters
Internal links help search engines:
Discover new pages
Crawl your website more efficiently
Understand relationships between topics
Identify your most important pages
Distribute authority throughout your website
They also help visitors explore related content without returning to Google.
Internal Links vs External Links
Internal Links
Connect pages within your own website.

Search Intent Explained
External Links
Point to pages on different websites.
Both types are valuable, but internal links directly strengthen your own website.
Build Topic Clusters
Google prefers websites that demonstrate expertise on a topic.
Internal linking helps create topic clusters.
Example:
On-Page SEO Guide
│
├── Title Tags
├── Meta Descriptions
├── Heading Tags
├── URL Structure
├── Image SEO
├── Alt Text
├── Internal Linking
└── Anchor Text
Every supporting article links back to the pillar guide while also linking to related articles.
Improve User Experience
Visitors rarely arrive on your homepage.
Most users land directly on one article.
Internal links encourage them to continue reading by offering relevant next steps.
This increases:
Time on site
Pages per session
User engagement
Pass Authority Between Pages
Some pages naturally earn more backlinks than others.
Internal linking helps distribute some of that authority to related pages.
This can improve the visibility of newer or less authoritative content.
Use Natural Anchor Text
Anchor text is the clickable part of a link.
Good example:
Learn more in our Keyword Research Guide.
Poor example:
Click here.
Descriptive anchor text helps both users and search engines understand what they'll find after clicking.
Link Relevant Content
Every internal link should make sense.
Ask yourself:
Would this genuinely help the reader?
Only link pages that naturally relate to the topic.
Common Internal Linking Mistakes
Avoid:
Linking every sentence
Using "Click here" repeatedly
Linking unrelated articles
Creating orphan pages with no incoming links
Forgetting to update older articles with links to newer content
Best Practices
Every article should:
Link back to its pillar page
Link to related supporting articles
Use descriptive anchor text
Help users continue learning
A good internal linking strategy grows stronger every time you publish new content.
