What is Internal Linking?
Internal linking is the practice of linking from one page on your website to another page on the same website. It's one of the most powerful and underutilized SEO techniques.
Why internal linking matters:
1. Helps search engines discover and crawl pages 2. Distributes PageRank (link equity) across your site 3. Establishes content hierarchy and topical relationships 4. Improves user navigation and engagement 5. Reduces bounce rate by guiding users to related content
Best practices: - Use descriptive, keyword-rich anchor text (not 'click here') - Link from high-authority pages to important pages you want to rank - Ensure every page has at least 3-5 internal links pointing to it - Use contextual links within content (more valuable than navigation links) - Build topic clusters: pillar pages linking to related spoke articles
Systematic internal linking can deliver 40-80% growth in organic sessions. It's often the highest-ROI SEO activity because it requires zero external resources.
Example
A blog post about 'How to Fix Core Web Vitals' should link to your glossary entry on Core Web Vitals, your technical SEO guide, and your free audit page — using keyword-rich anchor text for each.
