Google updated their webmaster tool with Data Highlighter and announced the launch of a new tool to help webmasters to create rich snippet markup (structured data) for their website’s pages. The tool is a point-and-click tool that lets a webmaster click on words or phrases and add elements of structure data to it without having to go into the code and add it to the HTML.
Google wants to show relevant and fresh updated content to their users and now they are pushing the website owners to add as much structured data to their sites as possible in order to improve and bring semantic in its search results and Knowledge Graph boxes with rich snippets like event listings, reviews and other information. However adding this kind of Microdata isn’t always easy for many small SEO or any other service providers don’t really have the expertise to add Microdata, Microformat or RDFa markup to their webpage and website
However,now you won’t have to fiddle with your code to report this data to Google. Google’ new Data Highlighter now offers a point-and-click tool for tagging your site to its specifications without having to touch any code.
For the time being, this tool is only available in English and only for structured data about events. Google promises to expand this project to other data types and languages in “the months ahead.”
Here is a statement from Google about Data Highlighter
Data Highlighter is a point-and-click tool that can be used by anyone authorized for your site in Google Webmaster Tools. No changes to HTML code are required. Instead, you just use your mouse to highlight and “tag” each key piece of data on a typical event page of your website.

This tool is very easy and simple to use but still I am not using this tool. Since it is currently available for Events markup and I had a doubt what if I use both HTML markups for rich snippet and then also use this tool to add markup will Google will consider it or not. If Google will consider than which markup will be considered by Google. For this lets wait for another Google update.
