Internal links connect one page on your website to another page on the same website. They help visitors discover related information and help search engines find pages and understand how content is connected. A good internal linking strategy is useful, relevant and easy to maintain. This guide explains how to plan and audit internal links without adding links just to manipulate rankings.
What is internal linking?
An internal link is a hyperlink that points to another URL on the same website. Examples include links from a blog post to a related guide, a service page to a case study, or a category page to an individual product.
Why internal links matter
- Discovery: Search engines commonly discover URLs through links from pages they already know.
- Navigation: Readers can move to useful supporting information without starting a new search.
- Context: Descriptive link text helps users and search engines understand the destination.
- Site structure: Links show how important pages and related topics connect.
Internal links do not guarantee rankings. Their value comes from helping users and crawlers access useful content in a logical way.
Types of internal links
- Contextual links: Links placed naturally inside article or page content.
- Navigation links: Main menu and other site-wide navigation links.
- Breadcrumb links: Links that show the page’s position in the site hierarchy.
- Related content links: Links to relevant articles, guides or products.
- Footer links: Supporting links in the footer, used when they help navigation.
How to build an internal linking strategy
1. Map important pages
List your main service pages, category pages, cornerstone guides and pages that support business goals. Identify which pages should be easy to reach from relevant sections of the website.
2. Group content by topic
Create topic groups around a central guide or category. Supporting articles should link to the central resource when it genuinely helps readers, and the central resource should point to useful supporting pages.
3. Find relevant linking opportunities
Review existing pages and look for places where another page answers a question, explains a term or offers a useful next step. Add a link only when it improves the reader’s experience.
4. Write descriptive anchor text
Anchor text is the visible clickable text. Use wording that tells readers what they will find after clicking. For example, technical SEO checklist is more informative than click here when linking to a technical SEO checklist.
Keep anchor text natural and varied where appropriate. Avoid forcing exact-match keywords into every link or using vague text for important destinations.
5. Link to the correct destination
Check that the target URL loads, is the preferred canonical URL and provides the information promised by the anchor text. Avoid redirect chains and links to broken or irrelevant pages.
6. Check important pages for orphan status
An orphan page has no meaningful internal links pointing to it. Important pages should normally be reachable through relevant navigation or contextual links. Do not add links to every low-value URL simply to remove an orphan warning from a crawler.
Internal linking examples
A beginner SEO guide could link to a detailed keyword research guide when explaining keyword selection. A local SEO article could link to a Google Business Profile guide when discussing business listings. A product category page could link to buying advice that helps shoppers compare products.
How many internal links should a page have?
There is no universal ideal number. Add enough links to help users explore useful related content, but avoid cluttering paragraphs, menus or footers with unnecessary links. The right number depends on the page length, purpose and available supporting resources.
Internal links and nofollow
For ordinary links between pages you control, use standard crawlable links in most cases. Do not add nofollow to every internal link as a routine SEO tactic. Use link attributes according to the purpose and trust context of the link.
How to audit internal links
- Crawl the website with a crawler or review important pages manually.
- Export source URLs, destination URLs, anchor text and HTTP status codes.
- Find broken internal links and update them to relevant working destinations.
- Identify important pages with very few internal links.
- Review orphan pages and decide whether they should be linked, consolidated or removed.
- Check for excessive links to redirects and update them to final URLs.
- Review anchor text for clarity, relevance and repetition.
- Re-crawl after changes and document the results.
Common internal linking mistakes
- Adding links that do not help the reader.
- Using the same exact-match anchor text unnaturally across the site.
- Linking to broken, redirected or irrelevant pages.
- Leaving important pages difficult to discover.
- Relying only on automated related-post widgets without reviewing relevance.
- Creating very deep navigation paths for important content.
- Removing old pages without updating links that point to them.

FAQs
Are internal links important for SEO?
Yes. They help people navigate and help search engines discover pages and understand relationships between content.
Should every blog post link to another post?
Link to another page when it adds useful context or a helpful next step. Do not add irrelevant links just to meet a target.
Do internal links pass PageRank?
Google uses links as part of its systems, including for discovery and understanding. Avoid treating internal linking as a guaranteed ranking formula.
What is an orphan page?
An orphan page has no internal links pointing to it from other pages on the site. Important orphan pages should be reviewed for discoverability and purpose.
