Information architecture (IA) is the “structural design of shared information environments; the art and science of organizing and labelling websites, intranets, online communities and software to support usability and findability.” (UX) is user experience; how easy the site is to navigate, how user friendly it is, how efficient is it in terms of bounce rates and site visit duration. Together, IA and UX form a perfect blend to create the ultimate user experience on your website.
