A database of user preference information is extracted and compiled from multiple websites by web-crawling robots without cooperation or specific participation by users. Users who interact with a website are frequently required to register and create a login or userID name that uniquely identifies them. Thereafter, when an individual rates an item, it is often recorded and published under their userID name such that other users can see how a specific individual rated the item. Although there is no requirement that a specific user register on different websites utilizing the identical userID, it is extremely common that this practice occurs and the use of identical userIDs on multiple sites is used herein to expand preference analysis beyond a single site. Once the database exists, users can request or be passively offered suggestions that result from preference associations across multiple websites as performed by a preference analysis and suggestion function.
