What is Schema Markup?
Schema markup is code (semantic vocabulary) that you place on your website to help the search engines return more informative results for users. If you’ve ever used rich snippets, you’ll understand exactly what schema markup is all about. Websites that use schema markup will rank better in the SERPs than companies without markup. One study determined that websites with markup rank an average of four positions higher in the SERPs than those without schema markup. While it’s not totally clear that this higher result is due to the markup alone, there is obviously some correlation
