What Is PageRank?

PageRank is the importance of a website, and one very important factor in determining how and where it appears in search engine results. The most important factor in PageRank is linkage. Every link is considered a vote for a page; links from established and credible sources count more. In addition, linking out to other credible pages can increase PageRank. Google’s algorithms are based on the assumption that important pages and information will be linked to more than the less important.
