What is Internal Linking?
Internal Linking refers to the link structure between pages on the same site. It governs PageRank flow, crawler discovery efficiency, and topical relatedness. In the GEO era it also drives entity coreference — AIs use anchor text to decide whether two pages describe the same entity.
How do you apply it in practice?
Best practice:
• 3–10 contextual internal links per page.
• Use descriptive keyword anchors, not 'click here'.
• Pillar links to all subtopics; subtopics back-link to pillar.
Why does it matter for AI search citations?
Generative search engines tend to extract sentences that are clearly defined, consistent and quotable on their own. Writing concepts like "Internal Linking" as one consistent definition across your site, backed by structured data and verifiable sources, lowers the chance of being misread. This improves readiness only; it does not guarantee citations or ranking gains — measure actual citations to know.

Topic Cluster
A Topic Cluster is a Pillar Page plus N subtopic pages connected by two-way internal links. It signals to Google that you cover a topic comprehensively and is the standard tactic for building Topical Authority.
Anchor Text
Anchor text is the visible text of a hyperlink. Google uses it to infer the target page's topic; over-optimization (a single keyword anchor exceeding ~30%) can trigger a Penguin-style demotion. In GEO it also influences AI entity resolution.
