Structured data helps search engines take the guess work out of understanding your content and the structure or your website. Its essential SEO.
Structured data is a way of adding code to your website pages which spells out to search engines what certain elements are. Its like saying, "This is a product" or "This is the products price" or "This is my review rating" or "This is the address of my business".
