What Does PageRank Measure in a site?

PageRank measure's a web page's importance on the internet. Page and Brin are the founders of page rank. Page and Brin's theory is that the most important pages on the Internet are the pages with the most links leading to them. PageRank thinks of links as votes, where a page linking to another page is casting a vote. because people do tend to link to relevant content, and pages with more links to them are usually better resources than pages that nobody links. It also looks at the importance of the page that contains the link. Pages with higher PageRank have more weight in "voting" with their links than pages with lower PageRank. It also looks at the number of links on the page casting the "vote." Pages with more links have less weight. Pages that are important are probably better authorities in leading web surfers to better sources, and pages that have more links are likely to be less discriminating on where they're linking. and page rank directly interacts with the revenue of that specific site's ads.
