Definition
What this term means
The practice of creating hyperlinks between pages within the same website to establish content relationships, hierarchy, and navigation pathways. Internal linking tells both users and AI systems how your content is organised, which pages are most important, how topics relate to each other, and where to find supporting information on related subjects.
Why it matters
The business impact
Internal linking is one of the most direct signals you can give AI systems about your content structure and topical relationships. Strategic internal links within content clusters help AI crawlers discover all of your relevant content and understand how topics connect. Pages with strong internal link support accumulate more authority and are cited more frequently by AI systems than orphaned pages with no contextual connections.
Used in context
How you might use this term
“An audit revealed that a company's highest-value service pages had minimal internal links, effectively making them orphan pages barely connected to the rest of the site. After implementing a strategic internal linking programme connecting them to blog posts, case studies, and related services, AI crawling frequency and citation rates for these pages improved significantly.”

Content Cluster
A strategic content architecture where a central 'pillar' page covering a broad topic is supported by multiple related pages that explore specific subtopics in depth. All pages in the cluster are interlinked, creating a web of content that signals comprehensive coverage to search engines and AI systems. This structure helps AI models understand the breadth and depth of your expertise on a subject.
Crawl Budget
The total number of pages that search engine and AI crawlers will fetch from your website within a given time period. Crawl budget is determined by a combination of your site's perceived authority, server performance, URL structure, and content freshness signals. Crawlers allocate their budget based on these factors, spending more time on sites they consider valuable and efficient to crawl.
Topical Authority
The perceived depth of expertise that a website or brand demonstrates on a specific subject area. Topical authority is built by comprehensively covering a topic across multiple pieces of interlinked content, demonstrating to both search engines and AI systems that you are a definitive, go-to source for that subject. It goes beyond publishing a single article to creating a body of work that covers a topic from every relevant angle.
