A seat ticket auction method and system using the Internet is provided. A user submits a tender for the auction of each seat while referring to a seating table, and also performs a search of an exhibition before submitting a tender during the auction. Further, when the seating table is referred to, information for a seat appropriate for a person in a wheelchair, and a simulation (view) of what a user will see of the stage from a seat are displayed on the terminal of the user. Three tender types, a personal tender, a complete group tender and an incomplete group tender can be selected. For the complete group tender, when a bid is not successful for all the members of the group, the bid is abandoned.
