How does it work?

This assumes that Your page is not fully integrated with HTML5’s data properties for microdata. This plugin will create small code inside Your full content, with extra microdata from schema.org. This will be ONLY on singular pages – post, page or your custom post type.

Once we are on singular page:

• we will extract from it EXCERPT.
• If You haven’t provided excerpt, plugin will look-up for post content, and downsize it to 170 symbols up to full word.
• If your content consist ONLY of shortcode, it will strip it out, and leave empty content. 🙁
• If we have empty content, from previous step, we will use post title. Not best choice, but at least we have some description.
• If Your post do not have even title, plugin will give up and your description will be empty. (This is very bad :’) )

Other options, like datePublished, dateModified (if enabled), UserComments (if enabled), url are taken from post

• SMC Facebook
• Author’s Facebook page
