Microformats and Schema.org
The Yoast SEO plugin adds some schema.org markup to your pages. It adds it to the following things:
If you’re using the Yoast SEO breadcrumbs, the plugin adds RDFa markup to the breadcrumbs. While Google states they support the Schema.org markup for breadcrumbs at times and also has docs on microdata, we have found this to be the most reliable method of implementing breadcrumbs for rich snippets.
Homepage for search
We add JSON+LD Schema for your search engine to your homepage, more about that feature in this post.
If you need to edit the URL or remove the JSON+LD schema you can do with this guide: Change the JSON+LD
When you have our Video SEO plugin, we add Schema.org videoObject markup to your videos.
Address and opening hours schema
When you have our Local SEO plugin, we surround your address with Schema.org markup and your opening hours with opening hours markup.
