The present disclosure discloses a method, a web server and a web browser of providing information. The method of providing information includes: in response to receiving a webpage access request of a user, obtaining, by a web server, attribute information of second product information that matches with first product information corresponding to a webpage which the user requests to browse; finding second product information which satisfies the attribute information; and sending the found second product information to a web browser used by the user in order for the webpage browser to include the received second product information in the webpage for provision to the user. The technical scheme of the present disclosure solves the problem of repeatedly performing actions (such as searching, clicking, browsing, etc.) by a user in an electronic commerce website and thereby wasting a relatively large amount of processing resources of the electronic commerce website under existing technologies.
