Internal linking
Internal linking is the set of links that connect the pages of a single site to one another. It distributes authority, guides navigation, and helps both Google and AI engines understand a site's thematic structure and page hierarchy.
Internal linking is the network of links that connect the pages of a single site. Done well, it channels authority toward the strategic pages, steers the visitor toward relevant content, and reveals to search engines and AI engines the hierarchy and thematic relationships between your pages.
How internal linking works
Each internal link passes a little authority and a relevance signal, carried by its anchor. Coherent linking connects pages on the same theme, from general to specific, and structures the semantic silo or the content cluster. AI engines also use it to map your expertise and navigate between your citable passages.
A concrete example
A "GEO" glossary page that links to "AI Overview," "brand mention," and the "GEO agency" service page — and receives links back from those pages — forms a dense cluster. This density of contextual links strengthens the entire theme in Google's eyes.
Why it matters
Without linking, even excellent content stays isolated and underused. Internal linking is what turns pages into coherent topical authority. It serves both SEO and GEO. To optimize it, see our SEO agency.
One relevant internal link beats ten forced ones. The descriptive anchor and the context make the difference.
Frequently asked questions
There's no ideal quota: each link should be relevant and contextual, with a descriptive anchor. A few useful links to related pages beat a pile of forced ones.
