Internal Linking Density.
How densely pages link to each other within the site. Strong internal linking signals topical authority and improves crawl depth for both search and AI engines.
How to improve internal linking density
- Every page should link to 3-5 related pages within the site
- Use descriptive anchor text matching the linked page's intent
- Maintain a clear cluster-and-pillar structure with bidirectional links
- Add 'Related content' widgets to programmatic pages
- Avoid orphan pages — every page should be reachable from the homepage in 3 clicks
How to measure progress
Crawl the site with Screaming Frog or similar. Count internal links per page. Identify orphan pages.
Common mistakes that erode internal linking density
- Linking only from blog posts, never to them
- Generic anchor text ('click here', 'this page')
- Orphan pages buried in /tags or /archive without contextual links
How CiterLabs handles internal linking density
CiterLabs's own site uses a Related Content widget on programmatic pages and dense bidirectional cluster linking.
