A system and a method for providing AD(ADvertisement) in real-time based on a keyword typed by a user, and a computer-readable recording medium storing a program thereof are provided to display an AD image or copy received from a keyword AD server around a keyword input window receiving a keyword from a user by transmitting the keyword inputted from the user in a predetermined unit to the search AD server. A keyword transmitter(101) transmits contents inputted to a keyword input window by a user to a search AD server in a phoneme unit, a word unit, a special character unit, and an alphabet unit. A search AD extractor(102) extracts AD data related to the user input contents received from the keyword transmitter from a search AD database and transmits the extracted AD data to a user web browser. A search AD receiver(103) receives AD image or character string data including URL(Uniform Resource Locator) information from the search AD data extractor. A search AD output unit(104) outputs the AD image and character string data received from the search AD receiver around the keyword input window of the user web browser without refreshing or moving a screen of the user web browser.
