Method for processing invalid click and system for executing the method

A method and a system for processing invalid click are provided to display no AD(Advertisement) in response to an AD display request received from an invalid click IP(Internet Protocol) address by checking the IP address of the user terminal generating the invalid click and registering the checked IP address as the invalid click IP address for the AD. An invalid click IP address checker(410) checks an invalid click IP address of a user terminal generating an invalid click for AD. An invalid click list storing part(420) registers and updates the checked invalid click IP address to an invalid click list by linking the invalid click IP address with the AD. A result page provider(430) provides a result page excluding the AD to the user terminal of the invalid click IP address when an AD display request is received from the invalid click IP address. The result page provider includes a result page generator(431), an IP address searcher(432) searching the IP address of the user terminal requesting the AD display request from the invalid click list, an AD checker(433) checking the AD linked with the IP address, and an AD processor(434) transmitting the result page excluding the AD to the user terminal.
