@seoguruApr 22.2015 — #First try to avoid using too much rich snippets in your website.
Second, using a rich snippet in your website is very easy, just go and check this schema-creator.org, here you can create schema codes for 7 different categories. After filling the simple forms here and getting code from this tool you can simply check for any possible errors in your code by using Google structured data testing tool.
I hope this does not sound sarcastic, but the fact is that you can use Rich Snippet by following the [url=https://developers.google.com/structured-data/rich-snippets/]Google guide to Rich Snippets[/url]. Just click on the highlight.
