What is Internal Linking?

Internal linking is one of the most underutilised SEO techniques for SaaS websites. Beyond helping search engines crawl and index content, strategic internal links pass PageRank (link equity) from high-authority pages to newer or less-visited pages. The hub-and-spoke model is the most effective architecture: each topic cluster has a hub (pillar page) that links to all spoke (cluster) articles, and each spoke links back to the hub. Key rules include: use descriptive anchor text (never 'click here'), ensure no orphan pages exist, place the most important internal link high in the content, and limit internal links to 5-15 per blog post. For Reddwise, every new blog post must link to at least 2 existing articles, and those existing articles should be updated with a link back to the new post. Breadcrumb navigation automatically generates hierarchical internal links.
