What is internal linking and why is it important for SEO?
Internal linking refers to the process of linking one page on a website to another page within the same domain. It’s a vital part of SEO internal linking because it improves crawlability, ensures proper indexation, and passes link equity throughout your site. A strong internal linking strategy helps search engines understand your website architecture and enhances user experience.
Without internal links, search engines struggle to find all your pages, especially if they’re buried deep in the navigation. When done right, internal link building also helps distribute link equity, improves on-page SEO, and guides users toward relevant content.
How does internal linking improve SEO rankings?
Internal linking improves SEO performance by:
- Enhancing crawlability for better indexation
- Distributing link equity to key content
- Supporting on-page SEO and anchor text optimization
- Strengthening the overall internal link structure
For example, linking from a high-authority blog post to a product landing page can help that page rank better in SERPs. This is especially helpful for newly created pages that need SEO support.
What are the best practices for internal linking?
The internal linking best practices 2025 include:
- Utilize keyword-rich anchor text naturally for effective anchor text optimization.
- The process of internal link building involves linking authority pages to new or low-performing ones.
- Maintain a clear site hierarchy
- Utilize contextual links in content clusters and pillar page strategy for effective content promotion.
- Perform internal linking audits as part of your SEO best practices
It is crucial to ensure that your internal links provide value to the reader. Don’t link just for SEO — guide users toward content that complements what they’re already reading.
How many internal links should I include per page?
A good range is 3–10 links per page depending on length. For the best internal linking strategy for blogs, place contextual internal links naturally throughout the article to relevant pages. Avoid over-optimization.
For example, a 2,000-word blog might comfortably include 10–12 internal links if spaced and structured logically within the content.
What’s the difference between internal and external links?
- Internal linking connects pages within your site and improves site architecture.
- External links point to other domains and help with off-page SEO credibility.
Both types of links serve different purposes and should be used together as part of your comprehensive SEO strategy.
What is link equity and how does internal linking pass it?
Link equity is the authority a link transfers from one page to another. Internal link building strategically passes this link equity to support deep pages and improve overall rankings. This is a crucial element in every internal linking strategy. When done right, even lower-traffic pages can boost higher-converting content through thoughtful linking and good anchor text optimization.
What is an orphan page in SEO?
An orphan page is one that lacks internal links pointing to it. These pages are hard to discover by search engines. A proper SEO internal linking audit can identify and fix orphan pages, keeping your internal link structure strong. Every piece of content should be accessible within 3 clicks from the homepage. Tools like Screaming Frog can help identify orphan pages in your sitemap.
What is anchor text and why does it matter in internal linking?
Anchor text is the clickable text in a link. Anchor text optimization ensures that internal links use descriptive, keyword-focused text that informs users and bots about the expected content. It also supports on-page SEO. The text advises the use of diverse and relevant anchor text for internal linking. For example, avoid repeated use of “click here” — instead, say “learn how internal linking improves SEO.”

- Trust-building content like testimonials or blog reviews
