Abstract: Client-server system for providing web site preview information of web site content and features to users. The user enters a web site URL they want to preview into a client application, which generates preview information about the web site content and features. The client generates the web site preview information by building the preview information from preview information sources including the web site and/or requesting preview information from the server/back-end of the client-server system. Both the client and the server build preview information by accessing preview information sources such as web pages and web page information databases, extracting the requested preview information, formatting the preview information in a standard preview format, and returning the preview information to the user for display.
