  • Publication number: 20140100956
    Abstract: A user alert system is described herein that provides direct alerts to users of a real estate website each time a single event meets one of a user's criteria. Unlike periodic summary reports that summarize all events within a regular time period, direct or “instant” alerts are delivered as soon as possible after a condition is met for a subject property or other source of the event, so that the user receives the most timely notification possible. Users can create a set of search criteria and then save the search for future reference. The user alert system leverages these search criteria to identify any item that matches the user's search criteria and provide a real-time notification in a timely manner upon any real estate event occurring that matches the user's search criteria. Thus, the user alert system allows users to find out about changes much more rapidly.
