Abstract: Disclosed is a web-site integration search method capable of consecutively searching a list of pre-registered search channels using a first keyword input by the user, even without inputting the first keyword in target search engines to be searched one by one. The method includes the steps of: inputting a first keyword in a keyword input window, and selecting one of multiple set search engines or all the set search engines; performing morpheme analysis of the input first keyword; generating a second keyword reconstructed through the morpheme analysis; adding an automatic execution instruction which sets the second keyword to be automatically input in an input window of the selected search engine; and receiving the second keyword, to which the automatic execution instruction has been added, transmitting the second keyword including the automatic execution instruction to a selected search engine through at least one output browser, and displaying searched information which is detected through the transmission.
