Internal Linking

Internal linking is the practice of connecting pages within the same site using hyperlinks, which shapes how crawlers discover content and how authority flows between pages.

Internal links serve three technical jobs. They give crawlers paths to find new and updated URLs, so a page with no internal links pointing to it is hard for Google to discover. They distribute ranking signals across the site, concentrating more equity on the pages that receive the most internal links. And the anchor text of an internal link gives Google context about what the destination page is about, which helps it match the page to relevant queries.

Site architecture is internal linking at scale. A shallow structure, where important pages sit only a few clicks from the homepage, helps both crawl efficiency and the perceived importance of those pages. Orphan pages, which have no internal links at all, often go uncrawled and unindexed. Descriptive anchor text beats generic phrases like "click here" because it passes topical relevance. Links should point to canonical, indexable URLs rather than redirects or noindexed pages.

For large sites, internal linking interacts directly with crawl budget. A clean link graph keeps crawlers on the URLs that matter and away from low value or duplicate paths. Auditing for broken internal links, redirect chains, and orphan pages is a routine part of technical SEO.
