Abstract: The invention is directed to techniques for generating web content to enable use of existing web content on a secondary web platform. Embodiments of the invention first extract an element of product content from product content for rendering a web page of a first web platform. The web content generator identifies whether the element of product content is authorized for use on a second web platform. If the element extracted is authorized for a second web platform, the element of product content is designated to be valid as web content for the second web platform. If not, the web content generator substitutes an authorized replacement product content element for the extracted element of product content. If no such authorized replacement product content element is available, the program generator designate the non-authorized extracted element of product content as needing replacement.
