The practice of linking between pages on the same site, used to help both users and search engines navigate a site’s structure and understand which pages matter most. Internal links pass authority between pages, establish topical relationships (a pillar linking to its cluster articles, for example), and give crawlers a path to discover deeper content that might otherwise sit orphaned. It’s one of the highest-leverage, lowest-cost technical SEO levers because it requires no new content — just better connections between what already exists. See the internal linking strategy guide and designing an internal linking experiment.
