To help you participate in structured data features, Google has just recently released two news tools, the Data Highlighter, and the Structured Data Markup Helper tool.
Data Highlighter
The Data Highlighter basically helps identify what sort of content you have on your site, and teaches Google the pattern of structured data about events on your website. Using the Data Highlighter, you won't have to modify the HTML of your existing page. Start by logging into Google Webmaster Tools, and then from the left sidebar, go to Optimization >> Data Highlighter. Then click on the button on the right that says Start Highlighting.
The Data Highlighter basically helps identify what sort of content you have on your site, You can now tell Google whether your site is among the following types listed.
- Articles
- Events
- Local Bussiness
- Movies
- Products
- Restaurants
- Software Applications
- TV Programs
After this, you will see an overview of that page, and you will have to tag each part of the page with your mouse. You can, for example, specify the author, the publishing date, and the average rating for an article. Tagging options vary depending upon what option you chose (i.e. Article, Product etc).
The process will take a few minutes, at the end of which the content will be 'highlighted' automatically.
Structured Data Markup Helper
It works in much the same way as Data Highlighter. You first have to tag various page elements with your mouse. Then, this tool will generate sample HTML code for you with microdata markup included. You can use this code as a reference for implementing structured data directly into your site's source code. Using these tools, you can really stand out from the competition. You can tell Google exactly what your website is about, and we think these tools are a huge step forwards.
