An advertisement providing method and system may allow improving the frequency of advertising exposure. In a method for providing an advertisement, a client sends a request message to a server. The request message requests an action of the server. The server determines whether an error occurs when performing the action. If the error occurs, the server extracts advertisement data based on information in the request message. The server creates a response message by combining the extracted advertisement data with error occurrence information, and sends the response message to the client.
