Structured Data for SEO-friendly content
What is Structured Data?

Structured data is data that's applied to a universal format, making it easily recognized, understood, and displayed by search engines.
Microformats, a popular type of structured data, allow text such as a business address or a product rating to be coded in such a way that places emphasis on the type of content and corresponding criteria.
How do microformats and structured data help my page?
Overall SEO
Microformatting adds a tremendous amount of weight to the type of data you're defining on a webpage. This provides webpages with better overall SEO ranking, because search engines have a better understanding of what the content refers to.
Helpful Snippets
Structured data is optimized in such a way that allows search engines (for example, Google) to craft helpful snippets for your page listings on the SERPs. Stocked with structured data recognizable to crawlers AND web browsers, the snippets are displayed beneath a link to your page on the SERPs.
Browsers who peruse these snippets get an extra-informative glimpse into your webpage, an understanding of how it relates to their search terms, and a legitimate incentive to click through to your site.
End result: help increase site exposure, popularity, and overall traffic.
Structured Data. It's a pretty big deal.
