How to Use Internal Linking for SEO: Beginner’s Guide (2025)

Internal linking is one of the most powerful on-page SEO techniques—and yet, it’s often the most overlooked. While backlinks get all the glory, your internal links are what help search engines crawl your site, understand your content hierarchy, and distribute authority between pages.

If you’re a WordPress beginner or just starting to learn SEO, internal linking might feel technical or confusing. But the truth is, it’s one of the simplest ways to improve your rankings, user experience, and content strategy—all without writing a single new blog post.

In this step-by-step guide, you’ll learn:

  • What internal links are and why they matter for SEO
  • Best practices for adding internal links naturally
  • How to structure your site for better crawling and authority
  • Tools that simplify internal linking in WordPress
  • Common mistakes to avoid—and how to fix them

What Is Internal Linking and Why It’s Crucial in 2025

Let’s start by understanding what internal linking is and why it’s absolutely essential for SEO in 2025.

What Is Internal Linking?

Internal linking is the practice of linking one page on your website to another page on the same domain. These links help users navigate your content—and help search engines crawl your site efficiently.

There are two main types of internal links:

  • Navigational links – Found in your menu, sidebar, or footer
  • Contextual links – Placed inside the body of a blog post or page (these are the most valuable for SEO)
For example, in this guide on internal linking, we might reference our SEO guide for beginners to give you foundational context. That’s an internal link.

Internal links aren’t just helpful for users—they’re vital for search engines.

Here’s why they matter more than ever in 2025:

  • They help Google discover new pages
    When a search engine bot lands on one page, it follows links to crawl the rest of your site. If a page has no internal links pointing to it, it might never be discovered—this is called an orphan page.
  • They distribute link equity (PageRank)
    Pages with more internal links pointing to them are seen as more important. Smart internal linking passes authority from high-performing pages to newer or lower-ranking ones.
  • They improve topical relevance and context
    Google uses anchor text (the clickable text of a link) to understand what the linked page is about. Linking to a guide using the anchor “on-page SEO checklist” helps reinforce that page’s topic.
  • They enhance user experience
    Internal links guide your readers to related content, keeping them on your site longer and reducing bounce rates—both of which are positive SEO signals.
Real Example:

If you're writing about SEO tips for WordPress, it makes perfect sense to link to your post on on-page SEO tips for WordPress beginners. This not only provides additional value to the reader, but it also reinforces the relevance and authority of both pages.

Internal Linking Best Practices for Beginners

Learning to use internal links effectively doesn’t require coding or plugins—just some smart strategies. Here are the top best practices every beginner should follow in 2025:

1. Use Descriptive, Natural Anchor Text

Anchor text is the clickable text in a hyperlink. It should be:

  • Relevant to the linked page’s topic
  • Natural, not forced or keyword-stuffed
  • Descriptive, so users and Google know what to expect

Don’t use: “click here” or “read more”
Do use: “check out our complete on-page SEO checklist”

Google uses anchor text to understand page relevance—so make it count.

Internal links perform best when placed within the body of your article, not just in footers or sidebars.

For example:
If you're discussing beginner tips, you could naturally mention and link to our SEO-friendly content guide.

Contextual links:

  • Improve SEO signals
  • Get more clicks
  • Help Google discover related pages faster

3. Keep It Balanced: Not Too Many, Not Too Few

You don’t need to flood your content with links. A good rule of thumb:

  • 2–4 internal links per 500 words
  • Only link when the page adds value for the reader

Overdoing it can overwhelm users. Under-doing it might leave SEO opportunities on the table.

Whenever you publish a new post:

  • Add links from older, relevant articles to it
  • Update the new post with links to existing content

This creates a connected content web that:

  • Spreads link authority
  • Helps Google find fresh content
  • Keeps your older content relevant and visible

Internal linking works best when it follows a strategy—not random guesswork. Here’s how to structure your internal links for SEO and usability.

1. Use the Pillar–Cluster Content Model

Create one comprehensive pillar post on a broad topic, then write supporting cluster posts on subtopics.

For example:
Your pillar could be What Is Technical SEO?, with cluster posts like:

Then:

  • Link clusters to the pillar
  • Link clusters to each other
  • Occasionally, link the pillar to the clusters

This helps search engines understand your site’s topical structure and improves rankings for all related content.

Don’t just link upward to a pillar page—also link sideways between related blog posts.

Example:
If you’re writing about internal linking, you should also connect to the post on on-page SEO checklist.

This improves:

  • Topic authority
  • User journey
  • Average session duration

Some pages are more important than others—like conversion pages, lead magnets, or cornerstone content.

Strategically:

  • Add internal links to these from your homepage
  • Link to them from high-traffic blog posts
  • Include them in your site navigation if relevant

This passes maximum link juice and visibility to your highest-value pages.

4. Don’t Forget About Orphan Pages

Orphan pages are those with no internal links pointing to them. Google may never find or rank them.

To avoid this:
Add at least one internal link pointing to each orphan page from a relevant post

Run an internal link audit

Find orphan pages using tools like Ahrefs or Screaming Frog

1. “I don’t understand what internal linking really means.”

Solution: Think of it like suggesting what your reader should read next. You’re simply connecting related posts on your site using clickable text.

2. “Where should I place the links?”

Solution: Inside the content. Contextual links (within paragraphs) are best. Avoid overloading sidebars or footers.

3. “How many internal links should I use?”

Solution: No fixed rule, but use 2–4 links per 500 words as a general guide. Don’t force it—link where it feels natural and valuable to the reader.

4. “How do I know what to link to?”

Solution: Start with your most important or related content. If you’re writing about SEO content, link to your on-page SEO tips. Over time, use audit tools to improve the structure.

5. “Can I mess this up and hurt my SEO?”

Solution: Internal linking rarely hurts SEO unless done excessively or manipulatively. If your links are helpful and relevant, you’re on the right path.
