Internal Linking
In one line
Internal linking is the practice of connecting pages within the same domain — and it shapes crawl efficiency, how authority flows between pages, and how users move through the site.
Going deeper
Internal linking is one of the most underrated SEO levers. You don't need outreach or negotiation — you fully control it — and yet most teams leave it untouched.
The core idea is to channel authority from pages that have it to pages you want to lift. Home, top categories and popular blog posts usually act as authority hubs, while newer content or conversion pages are the receivers.
Internal links are also the skeleton of any topic cluster. Pillar and supporting pages need clean, two-way links between them before a search engine will treat the domain as consistently authoritative on a topic.
