A method for offering an AD(ADvertisement) with a keyword inputted to an address window of a web browser in a client level is provided to effectively expose the web site of an advertiser on the web browser by using a history list showing web sites, which are previously connected by a user. A web server of an operator makes a table by receiving AD information comprising the URL(Uniform Resource Locator) of the web site, which is an AD target, and AD copy(S300), and stores it to a table storing part by transmitting it to an address window plug-in of the web browser of a user terminal(S400). To be referred by the web browser for forming the history list according to the keyword inputted to the address window, the address window plug-in stores a character string of the table to a history storing part referred by the address window plug-in(S600). As the keyword is inputted, the web browser forms/outputs the history list by using the stored character string and is connected to the web site of the URL by making the address window plug-in search/offer the URL to the web browser(S700).
