This document discusses the semantic web and why websites should implement it. The semantic web aims to make data on the web more easily understood by machines by linking related information. This allows searches to return more relevant results and data to be more easily found, shared and combined across websites. The document provides examples of how semantic web technologies like HTML5 microdata can be used to tag website content so it is better understood by search engines and machines. It argues that implementing these standards will provide benefits to users by improving search and allowing richer integration of online information.
