Abstract

A domain that hosts a general e-commerce marketplace establishes multiple sub-domains to host niche electronic marketplaces. These niche sub-domain sites are built around a concept and offer for sale items that relevant to that concept. The items may be selected from the general e-commerce marketplace at the host domain, or from other websites. The selected items are assigned at least one tag that is associated with the concept, thereby associating the items with the niche electronic marketplace. Other tags may also be assigned to the items to facilitate item searching and comparison. The sub-domain sites may also offer in-depth item information and a rich shopping experience that is tailored to the sophisticated shoppers who are familiar with the concept. As such, the sub-domain sites might offer professional-level commentary, community-based discussion forums, wiki-like product descriptions, blogs, and so forth.
