In today's Drupal tutorial series I will write down my notes, how to add open graph protocol for Drupal 8 website.
The Open Graph protocol enables any web page to become a rich object in a social graph. For instance, this is used on Facebook to allow any web page to have the same functionality as any other object on Facebook. While many different technologies and schemas exist and could be combined together, there isn't a single technology which provides enough information to richly represent any web page within the social graph. The Open Graph protocol builds on these existing technologies and gives developers one thing to implement. Developer simplicity is a key goal of the Open Graph protocol which has informed many of the technical design decisions.

Though we have missing one important element - image - there are no image. And honestly speaking I would love to have better control of what is shared in the title section, I don't want | [site:name] shared in it. And maybe I would like to have a better control of what is written in description box. Do you find the same? Then, let's fix that, and here comes in open graph protocol.
