Internal Linking Best Practices: Complete SEO Guide

Internal linking is one of the most important parts of a well-structured website.

An internal link is a link that connects one page on your website to another page on the same website.

For example, an article about Google Crawling could link to another article about Google Indexing.

Internal links help:

• Users discover related content
• Search engines discover pages
• Search engines understand website structure
• Distribute link value between pages
• Create stronger topic relationships
• Improve website navigation

A good internal linking strategy can make your website easier for both users and search engines to understand.

What Is Internal Linking?

Internal linking means linking from one URL on your website to another URL on the same website.

For example:

Learn more about [Google Indexing] to understand what happens after Google crawls a webpage.

Here, the Google Indexing page is an internal link.

Internal Link Example

<a href="/google-indexing/">Google Indexing</a>

The link points to another page on the same website.

Internal Links vs External Links

There are two basic types of links.

Internal Link

Connects two pages on the same website.

Example:

example.com/seo/ → example.com/internal-linking/

External Link

Points from your website to another website.

Example:

example.com/seo/ → anotherwebsite.com/seo-guide/

Both can be useful, but they serve different purposes.

Why Are Internal Links Important for SEO?

Internal links provide several important benefits.

1. Help Google Discover Pages

Search engine crawlers can follow internal links to discover other URLs on your website.

If an important page has no internal links pointing to it, it may be harder for crawlers and users to discover.

2. Help Search Engines Understand Website Structure

Internal links create relationships between pages.

For example:

SEO

↓

Technical SEO

↓

Google Crawling

↓

Google Indexing

This structure helps communicate how different pages relate to one another.

3. Help Users Find Related Content

Internal links can guide visitors to the next useful article.

For example, an article about:

What Is Topical Authority?

could link to:

• E-E-A-T Explained
• Internal Linking Best Practices
• Google Crawling
• Google Indexing
• Technical SEO

This keeps users within your website while helping them find additional information.

4. Help Distribute Link Equity

Internal links can help distribute signals associated with links throughout your website.

For example:

Homepage

↓

SEO Guide

↓

Technical SEO

↓

Google Crawling

A page receiving strong internal links can become more accessible within the site’s overall structure.

Internal Linking Best Practices

1. Use Relevant Internal Links

The most important rule is simple:

Link to pages that are genuinely relevant to the current content.

For example, an article about Google crawling could naturally link to:

Google Indexing

But linking to an unrelated page about celebrity news would not provide value.

Relevance should come first.

2. Use Descriptive Anchor Text

Anchor text is the clickable text used for a link.

Weak Example

Click here to learn more.

Better Example

Learn more about Google indexing.

The second example tells the reader what they will find after clicking the link.

Use natural descriptive anchor text rather than forcing exact-match keywords into every link.

3. Link From High-Authority Pages to Important Pages

Suppose your website has one article that receives significant organic traffic and backlinks.

You can identify relevant pages that would benefit from links from that article.

For example:

Popular SEO Guide

↓

Technical SEO Guide

↓

Google Crawling Guide

↓

Google Indexing Guide

This can help users discover deeper content and strengthen the site’s internal structure.

4. Link New Articles to Older Articles

When publishing a new article, look for older relevant pages that should link to it.

For example, if you publish:

What Is E-E-A-T?

Search your existing website for articles about:

• SEO
• Content quality
• Topical authority
• Google Search
• Helpful content

Add relevant internal links from those pages to the new article.

5. Add Links From Older Articles to New Articles

Don’t stop after publishing the new article.

Go back to older relevant articles and add links pointing to the new page.

This creates a two-way content relationship where appropriate.

6. Create Topic Clusters

Internal linking works particularly well with topic clusters.

For example:

Main Topic: SEO

Pillar Page

Complete SEO Guide

Supporting pages:

• Keyword Research
• Technical SEO
• On-Page SEO
• Internal Linking
• Google Crawling
• Google Indexing
• XML Sitemap
• Robots.txt
• E-E-A-T
• Topical Authority

Connect related pages together.

Example:

Technical SEO

→ Google Crawling

→ Google Indexing

→ XML Sitemap

→ Robots.txt

This creates a clear topical structure.

7. Link to Important Pages From the Homepage

Important pages should be easy to reach.

For example:

Homepage

→ SEO

→ Trading

→ Technology

→ Digital Marketing

If a page is extremely important to your business or website, make sure users don’t have to navigate through dozens of unrelated pages to find it.

8. Don’t Use Too Many Internal Links

There is no universal “perfect” number of internal links per page.

The right number depends on:

• Page length
• Topic
• Website structure
• User intent
• Number of related resources

Don’t add links simply to increase the number of links.

Every link should have a reason.

9. Avoid Orphan Pages

An orphan page is a page that has no internal links pointing to it.

For example:

Homepage

→ Article A

→ Article B

→ Article C

But:

Article D

has no links pointing to it.

Article D is effectively isolated from the site’s internal link structure.

Important pages should generally be connected to relevant parts of the website.

10. Use Breadcrumbs

Breadcrumb navigation can help users understand where they are within your website.

Example:

Home → SEO → Technical SEO → Google Crawling

Breadcrumbs can also provide additional internal links.

For larger websites, breadcrumbs can be particularly useful.

11. Link Deep Pages

Don’t link only to your homepage and major category pages.

Use internal links to connect deeper pages.

Example:

SEO

→ Technical SEO

→ Google Crawling

→ Google Indexing

→ Crawl Budget

→ Robots.txt

This creates a stronger website architecture.

12. Use Contextual Links

Contextual links are links placed naturally within the main content of an article.

Example:

Before optimizing your website, it is useful to understand how Google crawls websites.

The link is directly related to the sentence and gives the reader an obvious next step.

Contextual links are often more useful than adding a large list of unrelated links at the end of an article.

13. Link to the Most Relevant Page

Suppose you have three articles:

• What Is SEO?
• Technical SEO Guide
• Google Crawling Guide

If you’re writing about Googlebot, the Google Crawling Guide is probably the most relevant destination.

Don’t link to multiple pages just because they contain the word “SEO.”

Choose the page that best satisfies the reader’s next question.

14. Avoid Duplicate Internal Links When They Add No Value

If the same destination is linked repeatedly in a short section, it may not improve the user experience.

Use internal links naturally.

A long article can contain multiple links to an important page when appropriate, but avoid excessive repetition.

15. Keep Important Pages Close to the Main Navigation Structure

A strong website architecture might look like:

Homepage
│
├── SEO
│   ├── Technical SEO
│   │   ├── Google Crawling
│   │   ├── Google Indexing
│   │   ├── XML Sitemap
│   │   └── Robots.txt
│   │
│   ├── On-Page SEO
│   │   ├── Title Tags
│   │   ├── Meta Descriptions
│   │   └── Image SEO
│   │
│   └── Content SEO
│       ├── Topical Authority
│       └── E-E-A-T

This type of structure makes relationships between topics easier to understand.

How Many Internal Links Should a Page Have?

There is no fixed ideal number.

A 500-word article may need only a few relevant links.

A 3,000-word comprehensive guide may naturally contain many more.

Instead of asking:

“How many internal links should I add?”

Ask:

“Which pages would be genuinely useful to someone reading this article?”

That is a better SEO approach.

Internal Linking Strategy Example

Imagine your website is focused on SEO.

You have these articles:

1. What Is SEO?
2. What Is Topical Authority?
3. E-E-A-T Explained
4. How Google Crawls Websites
5. How Google Indexes Websites
6. Internal Linking Best Practices
7. XML Sitemap Guide
8. Robots.txt Guide
9. Technical SEO Guide

You could create this structure:

What Is SEO?

→ Topical Authority
→ E-E-A-T
→ Technical SEO

Technical SEO

→ Google Crawling
→ Google Indexing
→ XML Sitemap
→ Robots.txt
→ Internal Linking

Topical Authority

→ E-E-A-T
→ Internal Linking
→ Content Clusters

This creates a connected SEO knowledge base.

Internal Linking and Topical Authority

Internal linking can support a topical authority strategy by connecting related pages.

For example:

Topical Authority

↓

Topic Clusters

↓

Internal Linking

↓

Google Crawling

↓

Google Indexing

Each article addresses a different part of the larger subject.

The links connect these concepts and make the overall website structure clearer.

Internal Linking and Google Crawling

Internal links are particularly useful for helping crawlers discover URLs.

Consider this structure:

Homepage

↓

SEO Category

↓

Technical SEO

↓

Google Crawling

↓

Google Indexing

A crawler can follow these links to discover deeper pages.

This is one reason important pages should not be isolated.

Internal Linking and PageRank

Google’s original PageRank system used links as an important signal.

Internal links can help distribute link-based signals within your own website.

However, modern Google Search uses many systems and signals, so internal linking should not be viewed simply as a way to “push PageRank” to every page.

The best strategy is to create a useful, logical link structure.

Common Internal Linking Mistakes

Mistake 1: Using “Click Here” Everywhere

Use descriptive anchor text.

Mistake 2: Linking Unrelated Pages

Only link when the destination is relevant.

Mistake 3: Creating Orphan Pages

Important content should be connected to the website.

Mistake 4: Adding Hundreds of Links

More links don’t automatically mean better SEO.

Mistake 5: Ignoring Older Content

Update older articles with links to newer relevant content.

Mistake 6: Using Exact-Match Anchor Text Repeatedly

Keep anchor text natural and varied.

Mistake 7: Linking Only to the Homepage

Your deeper pages also need internal connections.

Mistake 8: Forgetting Mobile Users

Internal links should be easy to see and tap on mobile devices.
