Term: "Dynamic Content"

Dynamic content is web content such as Search Engine Results Pages (SERPS) that is generated or altered based on database information or user activity. Web pages that remain the same for all visitors in every context contain "static content." Many e-commerce sites now create dynamic content based on purchase history or cookies that have been left on the viewers PC and other factors. Search engines have a difficult time indexing dynamic content if the page includes a session ID number, and will typically ignore URLs that contain the variable "?" search engines will punish sites that use deceptive or invasive means to create dynamic content.
