Information architecture (IA) is all about mapping out the content on your web site for easier findability. There’s no Silver Bullet information system that can be applied to each and every project, because each web site serves different audience. Information architecture organizes categories in a sensible way to site’s visitors. IA deals with meta-data and search interaction patterns and researching and specifying easy to understand interface labels.
The field of Information Architecture overlaps with Content Strategy, the practice of planning the content production, publishing schedule, information ownership and information life-cycle.
