A method for pushing information, comprising: receiving a login request message including an instant messaging identifier sent by the user; after successfully authenicating the user, determining a target database; sending a query request including the user's instant messaging identifier to the target database, wherein the target database stores a plurality of user's instant messaging identifiers and corresponding data information, and data information that corresponds to the user's instant messaging identifier includes a Universal Resource Locator; receiving a query result from the target database, the query result including the data information corresponding to the user's instant messaging identifier, wherein the data information corresponding to the user's instant messaging identifier is looked up in the target database based at least in part on the user's instant messaging identifier; acquiring data content corresponding to the URL included in the data information corresponding to the user's instant messaging identifier, wherein the data content is merchandise information that the user is going to publish; determining an instant messaging client to push the acquired data content, the determination being based on the user's instant messaging identifier, comprising: determining whether the data information includes time information, wherein the time information includes a time interval, wherein the data information looked up using the user's instant messaging identifier is valid within the time interval and invalid at other times; and in response to a determination that the data information includes the time information: comparing local operating time with requirements of the time information, comprising; determining whether the local operating time falls within the time interval; and in the event that the local operating time does not fall within the time interval, determining that the local operating time is not within the requirements of the time information; and in response to a determination that the local operating time is not within the requirements of the time information, omitting to determine the instant messaging client based on the user's instant messaging identifier; and pushing the data content to the determined instant messaging client, comprising: omitting to push the data content in the event that the instant messaging client is not determined. receiving a login request message including an instant messaging identifier sent by the user;
