Abstract: Co-brands, virtual wrappers for web sites that allow clients to expand client inventories across different web sites, are disclosed. Different types of travel inventory can be provided across these web sites. A client can create different URLs, domains, look and feel, product filters, pricing rules, business logic, payment methods, languages, currencies, etc. off a single instance. A client can create a co-brand and, using an administrator application, configure its settings to target specific geographic locations, targets markets or even themes. Additionally, co-brands are used to allow third party vendors to direct traffic to client sites. Co-brand tools are designed to make items such as navigation, images, buttons, domain names, colors, fonts, languages and currencies. Co-brands make it easier for travel companies to have sites based on demographics, destination, and events that can lead to greater adoption and conversion.
