PageRank is an algorithm originally developed by Google to measure the importance of web pages based on the quantity and quality of links pointing to them.
PageRank works by modelling links as votes. Each link transfers a portion of authority from one page to another, with links from highly trusted pages passing more value than links from weaker ones.
Although Google no longer shows public PageRank scores, the concept is still embedded in modern ranking systems. Both internal and external links contribute to how PageRank flows through a website.
Effective SEO focuses on directing PageRank toward important pages using clear site structure, internal linking, and earned backlinks.
