PageRank is a link analysis algorithm used by the Google search engine, which allocates a numerical weighting to each element of a hyperlinked set of documents with the principle of measuring its relative importance within the set. In Google algorithm, PageRank is a probability distribution used to symbolize the likelihood that a person randomly clicking on links will arrive at any meticulous web page. PageRank can be computed for compilation of documents of any size. The PageRank calculations necessitate several passes, known iterations, through the collection to adjust approximate PageRank values to more closely reflect the theoretical true value. A probability is defined as a numeric value between 0 and 1. A 0.7 probability is commonly expressed as a “70% chance” of something happening. Hence, a PageRank of 0.7 means there is a 70% chance that a person clicking on a random link will be directed to the document with the 0.7 PageRank.
