Why Is Internal Linking So Important?
Internal links are your website's navigation system — for users, search engines, and AI crawlers alike. They distribute authority (link equity) across your entire site and help with topical categorization.
Core Principles of Effective Internal Linking:
- Flat hierarchy: Every important page should be reachable in a maximum of 3 clicks
- Contextual links: Links within body text with descriptive anchor texts
- Hub-and-spoke model: Pillar pages link to cluster pages and vice versa
- Breadcrumbs: Structured navigation that also serves as Schema.org markup
- Footer and sidebar links: Supplementary navigation for secondary pages
Common Mistakes:
- Orphan pages without incoming links
- Excessive navigation with hundreds of links per page
- Generic anchor texts like "click here" or "learn more"
- Broken links leading to 404 error pages
Optimal Site Architecture:
- Homepage → Category pages → Detail pages → Content clusters
- Topical silos for clear relevance signals
- XML sitemap as additional orientation for crawlers
