Internal Linking, explained properly.
What is internal linking?
Internal linking is the practice of linking from one page on your website to another page on the same site. These links help users navigate, distribute authority (sometimes called link equity), and tell search engines how your content is structured. Google's SEO Starter Guide highlights strong internal linking as a signal of site quality. Linking to your technical SEO service, or to a meta title glossary entry, are both internal links. They are more than navigation: they are one of the most underrated tools in your SEO toolkit.
Why internal linking matters for SEO
If Google cannot find your content, it will not rank. Internal links help search engines discover new pages, understand your hierarchy and pass ranking power from high-authority pages to others that need a lift. They also support good crawlability. Done well, internal linking can: - Improve crawlability and indexation - Strengthen topical relevance and topical authority - Spread link equity across your pages - Reduce bounce rate and increase time on site
Types of internal links
- **Contextual links:** links in the body of your content, such as blog posts or service pages. - **Navigation links:** menus, footers and sidebars. - **Breadcrumbs:** hierarchical links like Home > Blog > SEO Tips. - **Related content modules:** "you might also like" blocks. Contextual links tend to be the most powerful for SEO, especially when surrounded by relevant content.
How Google uses internal links
Google follows internal links to discover new URLs, understand how pages relate to each other, and judge the importance of pages based on how many internal links point to them. Pages with more internal links are seen as more important, so use that to your advantage.
Best practices for internal linking
### 1. Use descriptive anchor text Avoid "click here" or "this page". Use natural, keyword-relevant anchor text that explains what the user will find. Instead of "learn more", try "learn more about our SEO training". ### 2. Link from high-authority pages Your homepage, top-performing blog posts and cornerstone guides carry more authority. Link from these to your newer or less visible content. ### 3. Keep a flat site structure No page should be more than three clicks from the homepage. Use internal links to flatten your architecture and improve accessibility. ### 4. Link to related content Guide users through their journey. If they are reading about Core Web Vitals, link them to page speed or technical SEO for context and conversion potential. ### 5. Use tools to audit and scale Screaming Frog and Sitebulb can crawl internal links and spot orphaned pages, which are pages with no internal links pointing to them.
Common internal linking mistakes
These issues appear in almost every audit: - Too many internal links on one page, which dilutes authority - Broken or redirected internal links, which hurt user experience and crawl efficiency - Linking to thin or irrelevant pages, which confuses users and bots - No internal links to high-value commercial pages, which is a big missed opportunity Fixing these is a quick win and one of the easiest ways to improve rankings without creating new content.
How internal linking fits a wider strategy
Internal linking is mapped during the SEO strategy phase, clustering related content and identifying which pages should support each other. Internal links are then used to strengthen topic clusters, support conversion journeys, and make sure every core page is supported and discoverable. This glossary is itself an internal linking asset: each term links to related terms and services, keeping users engaged and Googlebot crawling.
Internal Linking: common questions.
How many internal links should I add per page?
Enough to be useful, with no fixed target. Typical content pages have 5 to 20 internal links to related pages, navigation and supporting content. Pillar pages might have 30 to 50. Do not add internal links for the sake of a count; add them where they genuinely help users.
Should I always use exact-match anchor text for internal links?
No. Vary anchor text to look natural and show topical breadth. Mix exact-match keywords with related phrases, brand mentions and natural language. Exact-match anchors on every internal link look artificial and provide less topical signal.
Where should internal links point to?
Three patterns work well. From new content to related existing content, which helps topical clustering. From high-authority pages to pages you want to rank, which passes authority. Between sibling pages on related topics, which builds topic cluster signals. Avoid linking only to top-level pages; deep internal links matter.
Can I have too many internal links?
Yes, but only at extremes. A page with 200 or more internal links dilutes the value each one passes. For most pages, 10 to 30 internal links sits well within a healthy range. Focus on quality and relevance over quantity.
