PageRank
Google's core algorithm signal that weighs inbound links; high-quality backlinks from authoritative sites improve rankings.
Definition
PageRank is the link-based ranking signal at the core of Google's algorithm: pages that receive links from other important pages are considered more important. A single high-quality backlink from an authoritative domain can significantly affect rankings. Links pass PageRank by default; rel="nofollow" or rel="sponsored" instructs Google not to pass it. Internal links distribute PageRank within your site.
Relevance to GEO
Domain and page authority (influenced by PageRank and backlinks) correlate with how often AI systems cite a source. Building quality backlinks and a strong internal linking structure supports both traditional SEO and GEO visibility.
