PageRank is Google's original algorithm for measuring the importance of web pages based on their links. Pages with more quality links are considered more authoritative.
PageRank, named after Google co-founder Larry Page, treats links as votes. A link from an important page counts more than one from an unknown page.
Google no longer shows a public PageRank score, but the underlying concept — links as authority signals — remains core to how ranking works today.
The public score is gone, but link-based authority is still fundamental.
