title: Schema.org: What to use, Microdata or JSON-LD?
body: <p>The data markup <a href="http://schema.org/" rel="nofollow">Schema.org</a> for search sites like Google, Yahoo!, Bing and Yandex is great for snippets. However, I perceive that most of webmasters use Microdata and almost never use <a href="http://json-ld.org/" rel="nofollow">JSON-LD</a>. I learned about JSON-LD recently and I have some doubts:</p>
  
  <p>Could I use it without compability problems with search engine?</p>
