What are Open Graph tags?

Open Graph tags are meta tags that tell social platforms what title, description and image to show when your link is shared. Twitter uses its own twitter:card tags on top. If they are missing, networks guess, and your link looks broken. This tool fetches a page and shows exactly what each platform will display.
