In order to trace the changes of a Web page, the search engine needs to save many snapshots of it, that will increase the storage usage of the server. This paper introduces the method of delta encoding to save disk space. In order to let users understand global changes of all the snapshots and the detail changes of every two snapshots easily, this paper introduces the method of visualization.

Key wordsDelta encoding      Page snapshot      Visualization
