Google reads a variety of structured data from webpages, including e-commerce Product details, Recipes, Reviews, etc. — along with three standard Schema types from a website’s homepage: WebSite, Organization, and Person. In this post we’ll focus on the Organization markup, which Yoast SEO, WPSSO Core, and most SEO plugins add to a site’s homepage. Google uses the Organization markup to enrich its Knowledge Graph information for the website’s Organization (aka Business, Corporation, etc.).
See Google’s About Search Features and Structured Data General Guidelines webpages for more information about the current Schema types recognized by Google.
See Google My Business, Your business information in the knowledge panel, and Improve your local ranking on Google for more information about Knowledge Graph and Google’s local business markup.
An Organization markup from the Yoast SEO plugin (and most SEO plugins) looks like this:
