Internal linking and topical authority
Internal links are one of the most underused SEO levers. Here is how to use them to build topical authority and help both crawlers and AI engines understand your site.
Internal links are the connections between your own pages. They are fully in your control, cost nothing, and yet most sites barely use them. Done well, they spread authority, guide crawlers, and signal what your site is really about.
Why internal links matter
- They pass ranking signals from strong pages to weaker ones.
- They help crawlers discover and prioritize pages.
- They map relationships, which helps engines understand topics.
- They keep readers moving through your content.
Build topic clusters
Organize content into clusters: a broad pillar page on a topic, linked to and from focused pages on subtopics. This structure concentrates authority and tells engines you cover the subject deeply.
Use descriptive anchor text
The clickable text of a link describes the destination. Use clear, relevant phrases instead of generic "click here". Anchor text is a strong relevance signal for both search and AI engines.
A practical routine
- When you publish a page, link to it from related existing pages.
- From the new page, link out to your most relevant pillar and supporting pages.
- Periodically find orphan pages with no internal links and connect them.
- Fix broken internal links, they waste authority and frustrate readers.
Every new page is a chance to strengthen the pages you already have.
