Abstract: The present invention is to provide a method for analyzing, matching and delivering questions of an online game, which is applied to a question-and-answer server (Q & A server) linked to a plurality of user terminals (such as personal computers, hand-held mobile phones and etc.) respectively. When the Q & A server receives a question signal transmitted from the user terminal, the Q & A server executes the steps of determining whether the question signal includes at least one of keywords preset in a keyword database; reading property tag corresponding to the keyword from a tag database; determining whether property tags preset in a plurality of user accounts in a user database are matched with the property tag corresponding to the question signal; and transmitting the question signal to user terminals corresponding to the user accounts, which have the property tags matched with the property tag corresponding to the question signal.
