Point-and-click your way to Schema.org
“Google wants website owners to add as much structured data to their sites as possible in order to improve its search results and Knowledge Graph boxes with rich snippets like event listings, reviews and other information. Adding this kind of metadata to a site, however, isn’t always trivial, and many small businesses don’t really have the expertise to add microdata or RDFa markup to their sites.
Starting today, however, you won’t have to fiddle with your code to report this data to Google. The company’s new Data Highlighter now offers a point-and-click tool for tagging your site to its specifications without having to touch any code.”
