Methods and apparatus for matching a real estate listing to a buyer profile and creating a marketing campaign based on the buyer profile are disclosed. The presently disclosed correlation and marketing system processes a plurality of previously executed real estate transactions to create a knowledge database. The knowledge database stores correlations between real estate attributes, buyer attributes, advertiser attributes, and publisher attributes. When a new real estate listing is entered in to the correlation and marketing system, the system uses the knowledge database to determine a buyer profile for that real estate listing. The correlation and marketing system also automatically generates a recommended marketing plan, marketing activities or media buys for that buyer profile based on the associated attributes. The real estate agent may then adjust the marketing plan. Once the marketing plan is accepted, it is automatically executed.
