An "aggregator site" is a site in which the website goes out and seeks the information. In other words, it's not information that is loaded into the system. Aggregator sites like sidestep, kayak, and mobissimo go out. They seek the information from, for example, the airline's website or the hotel's website and then they bring it back and present it to you so you are getting information that is very, very current and up-to-date.
