Structured Data in Action: Google Rich Snippets
As we also discussed in the last article, Google is using structured data to display Web content in search results using what they call “Rich Snippets.” The Rich Snippets feature will check a web page for structured data and display it accordingly in search results. Here is an example from Google's blog, that shows the search results of a page whose content is marked up with the hReviews format:
Most of the time optimization efforts for semantic search take place behind the scenes, but Rich Snippets is a way you can actually see tangible results right away.
Google also has a Rich Snippets testing tool you can use to check the content of your page to ensure your marked-up content is compliant. Here are the results from the page we placed our hCard example code onto:
If there are any errors in the mark up, the tool will point them out.
Using microformats to mark up simple content as structured data is not a difficult task as demonstrated here, but if you have a lot of relevant content to mark up like ongoing reviews or a lot of products, you should add microformat classes and styles directly into your existing CSS stylesheets. You can utilize tools like Oomph, a microformats toolkit, to help undertake the task.
Upcoming articles in this series will cover how to use the RDFa markup standard for structured data as well as an introduction to linked data.
