Which search engines use schema?

Today, Google, Bing, and Yahoo! are announcing the creation and support of a common set of conventions for structured data markup on web pages through the launch of schema.org. Webmasters wishing to add markup to their pages to make their websites easier for search engines to comprehend should visit Schema.org, which promises to be a one-stop shop for resources.

The search engine is specifically informed by schema markup what your content on your website is attempting to say. Unstructured data is transformed into structured data. By incorporating schema, you can improve how a search engine crawls a website and improve its ranking while still adhering to other smart SEO practises.
