Internal linking is unusually high-leverage because, unlike backlinks, it's entirely within a site owner's control — no outreach or luck required, just deliberate planning. It serves three functions simultaneously: it helps search engines discover new or deep pages faster, it distributes link equity from strong, well-linked pages toward newer or weaker ones that need a boost, and it helps users navigate to related, useful content, which supports engagement metrics. Best practice is to link using descriptive, varied anchor text (not always the exact match phrase), to link from genuinely relevant context rather than forcing unrelated links in, and to prioritize links from a site's highest-authority pages (its homepage, its most-linked blog posts) toward pages that most need the support.
Example
A new comparison page gets linked from three existing high-traffic blog posts within its first week, rather than waiting for it to earn authority purely through external backlinks and time.
