PageRank is an algorithm developed by Google that determines the importance of a webpage. It is used to calculate a website’s ranking in search engine results pages (SERPs). A higher PageRank indicates that a website is more important and authoritative, and will therefore be ranked higher in SERPs.
There are a number of factors that affect a website’s PageRank, including the number and quality of backlinks, the age of the domain, and the website’s content. Websites with high-quality content and a lot of backlinks from other reputable websites will typically have a higher PageRank.
