Internal linking is the practice of adding hyperlinks between pages on the same website. It serves two key purposes: helping visitors navigate to related, useful content, and helping search engines understand the relationship and relative importance between pages on a site.
Strategic internal linking can meaningfully boost the ranking potential of important pages by directing link equity toward them from other relevant, established pages on the same site — a lever entirely within your control, unlike earning external backlinks.
A common mistake is under-linking to newer or deeper pages, leaving them isolated with little internal support. A well-structured internal linking strategy, often organized around topic clusters and pillar pages, ensures authority flows to the pages that matter most.
Internal linking architecture is a core focus of our On-Page SEO service.
