Internal linking
Links between pages on the same site; they define the content graph for crawlers and AI agents and distribute authority.
Definition
Internal linking is the practice of linking from one page on your site to another. For SEO, internal links distribute PageRank and help crawlers discover content. For AI agents, they define the navigation graph: which pages are important, how topics relate, and where to go for more detail. Key concepts include link depth (clicks from homepage — keep important pages within ~3 clicks) and anchor text (descriptive text that signals what the linked page is about).
Relevance to GEO
Strong internal linking helps agents discover and prioritize pages, follow topic chains, and treat well-linked pages as more authoritative. Avoid orphan pages (no inbound internal links); ensure every important page is reachable from a main entry point.
