What Is Internal Linking?
Internal linking refers to linking one page of your website to another page of the same website. These links help users navigate and help search engine bots understand your site’s structure, hierarchy, and content relevance.
Examples:
- Linking your homepage to your main category pages
- Linking your blog posts to related blog posts
- Linking cluster pages to pillar pages
Internal links guide visitors and search engines toward your most important content. When implemented effectively, they become a powerful SEO weapon.
Why Internal Linking Is Important for SEO
Internal links are essential because they:
1. Improve Crawlability
Search engines follow internal links to crawl deeper pages. If your pages aren’t well linked, they may remain undiscovered or indexed very slowly.
2. Distribute Link Equity
Internal links pass authority from high-ranking or high-authority pages to other important pages. This is known as link equity or “link juice.”
3. Build a Clear Site Structure
A strategic internal linking structure guides Google to understand relationships between your pages. This helps establish topical authority.
4. Increase Page Views & Reduce Bounce Rate
Users spend more time on your website when they find useful related content through internal links.
5. Boost Keyword Rankings
Using internal linking anchor text that includes keywords helps Google understand what the target page is about, improving its visibility.
Types of Internal Links
Before building a strategy, you must understand the types:
1. Navigational Links
These appear in menus, header, footer, and sidebar. They help users reach key sections easily.
2. Contextual Internal Links
These appear naturally inside the content body. They are the most important for SEO because they provide context.
Example:
“In our detailed guide on topic Organic Search vs Paid Search – Simple SEO Guide for Beginners, we explained difference between Organic and Paid Search.”
3. Footer Links
Useful for linking important but less frequently accessed pages.
4. Breadcrumbs
A secondary navigation system that enhances user experience and site hierarchy.
Internal Linking Strategy – Step-By-Step Guide
Step 1: Create Your Pillar Pages and Topic Clusters
A solid internal linking system begins with a strong content structure.
Pillar Pages
These are comprehensive, high-level pages that cover a broad topic.
Examples:
- “Internal Linking Strategy”
- “On-Page SEO Guide”
- Cluster Pages
These are smaller, in-depth pages related to a pillar topic.
Examples:
- “How to use anchor text for internal links”
- “Internal linking best practices for 2025”
How to link:
- Cluster pages must link back to the pillar page
- Pillar pages should link to all related cluster pages
- Cluster pages should interlink where relevant
This creates a topic cluster model, which is one of the most powerful SEO frameworks.
Step 2: Identify Important Pages You Want to Rank
Not all pages need equal link equity. Prioritize pages that:
- Drive revenue or conversions
- Are long-form guides
- Target high-search-volume keywords
- Are ranking on page 2 (positions 11–20)
- These will benefit most from contextual internal links.
Step 3: Fix Orphan Pages
Orphan pages are pages with no internal links pointing to them, making them nearly invisible to Google.
To fix them:
- Use tools like GSC, Ahrefs, Screaming Frog
- Identify pages with zero “Inlinks”
- Add contextual internal links from relevant content
A page must have at least 2–3 internal links for proper discovery.
Step 4: Add Contextual Internal Links From High-Authority Pages
This step provides the biggest benefit.
Identify your top pages:
- High traffic blog posts
- Authoritative guides
- Pages with strong backlinks
- Add contextual links from these pages to the pages you want to boost.
Anchor text example:
“A Simple Beginner’s Guide to Search Engine Optimization”
Always use descriptive, keyword-rich anchors.
Step 5: Use the Right Anchor Text
Anchor text is the clickable text of a link. It gives context to both users and search engines.
Types of anchor text to use in internal links
- Exact-match anchor text (used sparingly)
- Partial-match anchor text
- Long-tail keyword anchor text
- Natural descriptive anchor text
- Branded + keyword combinations
Avoid
- Generic text like “click here”
- Over-optimization of exact match
- Repeating the same anchor for every link
Google uses anchor text to understand what the target page is about, so it must be relevant.
Step 6: Maintain a Logical Click Depth
Click depth refers to the number of clicks required to reach a page from the homepage.
Best practice:
- Keep important pages within 3 clicks from the homepage
- Use breadcrumbs, sidebars, or “related posts” to reduce click depth
- Shallow click depth improves crawl speed and indexation.
Step 7: Use Internal Links to Update Old Content
Adding fresh internal links to old pages signals Google that:
- The page is updated
- The content is still relevant
- This often results in ranking improvements.
For old posts, add:
- Links to new articles
- Links to updated guides
- Links to pillar pages
This improves both user experience and SEO.
Step 8: Avoid Common Internal Linking Mistakes
Some practices can harm SEO rather than improve it.
Avoid:
- Creating too many internal links on a single page
- Using the same anchor text repeatedly
- Linking unrelated content
- Using footer links excessively
- Not updating internal links after URL changes
- Ignoring mobile-friendly navigation
- Internal linking must be intentional - not random.

Here are best practices to follow for the best results:
- Use 2–5 contextual internal links per 1000 words

- Use keyword-rich anchor text naturally
