The present invention makes it possible to preread Web pages according to individual users' visiting habits and preferences in combination with mass users' visiting history, and find out Web pages that a user is most likely to click through computational analysis of weights and preference coefficients on different page elements of Web pages, thereby realizing more precisely prereading, significantly increasing success rate of preread. Further, pages are downloaded in idle period, which advantageously saves time for users by substantially avoiding waiting.
