Internal Linking.

Internal linking is the practice of creating hyperlinks between pages on the same website. Internal links serve three purposes: they help search engine crawlers discover and navigate pages; they distribute link equity (PageRank) from high-authority pages to those needing a ranking boost; and they guide users to related content that extends their session and deepens their engagement with the site.

Strategic Internal Linking

Effective internal linking is intentional, not accidental. Audit which pages receive the most external backlinks (high-authority 'hub' pages) and ensure they link to strategically important pages that need authority. Use descriptive, keyword-relevant anchor text rather than generic phrases. Add contextual links within body content—these pass more equity than navigation or footer links. Identify orphan pages (reachable only via sitemap or external links) and add internal links to them.

Internal Linking and Topic Clusters

The topic cluster model is fundamentally an internal linking strategy: the pillar page links to all cluster pages, and each cluster page links back to the pillar. This bidirectional linking creates a tightly connected content hub that collectively outranks siloed individual pages. Regular content audits should identify internal link opportunities in existing content—adding 2–3 relevant internal links to each new piece of content and retrospectively adding links from older posts to new ones is standard practice.
