Internal Link Flow
The deliberate design of internal links to signal topical authority to AI crawlers and route importance to your key pages.
Plain Language Definition
Internal link flow is the deliberate planning of how your website’s pages link to each other to guide search engines through your most important content and establish topical hierarchies. Hub pages link to related deep pages; deep pages link back to the hub and to related topics. This structure tells AI crawlers what you are an authority on and how different topics relate.
Technical Definition
Mathematical planning of internal link topology to route PageRank-equivalent flow signals and establish clear topical hierarchies — directing crawler traversal through logical conceptual paths that signal content authority distributions to search and AI retrieval systems.
Why This Matters for AI Search Visibility
AI crawlers treat internal links as relevance signals: pages that many internal pages link to are treated as more important. Deliberately routing internal links through your most authoritative content — glossaries, pillar pages, case studies — amplifies those pages’ authority signals.
