| Abstract: | The large- scale website is the core of the network in- formation, The bigness of its information and the rapidness of the renewal speed predominate over which of the middle and small scale website, So the quality of search to large - scale website homepage directly influence the performance of the search engine. On the base of analyzing classified refresh policy, This article proposed one increase type information renewal method according to the characteristics of large- scale websites.
