PageRank

Definition

PageRank is Google's original algorithm for ranking web pages based on the quantity and quality of links pointing to them. Named after Larry Page, it treats each link as a vote. While Google no longer publicly shares PageRank scores, the underlying concept of link-based authority still influences rankings.

Why It Matters for SEO

PageRank established the foundational principle that links are endorsements. Modern ranking algorithms have evolved far beyond simple link counting, but the core idea that authoritative, well-linked pages rank higher remains central to SEO.
