Google's algorithm on PageRank is analyzed in details. Some disadvantages of this algorithm is presented, for instance, preferring old pages, ignoring special sites and inaccurate judge of hyperlinks pointed out from one page. Furthermore, author's improved algorithm is described. Experiments show that the author's consideration on evaluating the importance of pages can make an improvement over the original algorithm. Based on this improved algorithm a topicspecific searching system have been developed.
