Abstract: Techniques for providing dynamic categories are disclosed. In some embodiments, a system for providing dynamic categories includes receiving user context data, and dynamically determining a plurality of categories for the user based on the user context data, in which the plurality of categories are for categorizing content on a web site. For example, the user context data can be based on monitored user behavior on a web site, and one or more of the plurality of categories can include a synthesized category on the web site that is dynamically generated based on the monitored user behavior on the web site.

Abstract: Techniques for dynamic landing pages are disclosed. In some embodiments, a process for providing dynamic landing pages includes selecting a dynamic landing page in response to a request for a Uniform Resource Indicator (URI) (e.g., destination URI) of a web site using a dynamic selector engine; and returning the dynamic landing page using a proxy service. For example, the dynamic landing page can correspond to a web page that is returned in response to the request for the destination URI, and the web page can include customized content (e.g., including a widget) that is targeted for a campaign, channel, source, and/or user.
