It counts the number, and quality, of links to a page which determines an estimation of how important the page is. The more quality backlinks the higher Google Pagerank. It is assumed in several research papers that the distribution is evenly divided among all documents in the collection at the beginning of the computational process. The PageRank computations require several passes, called “iterations”, through the collection to adjust approximate PageRank values to more closely reflect the theoretical true value. The underlying assumption is that more important websites are likely to receive more links from other websites.
