OpenGraph Tags - Functional specification

This documentation provides technical information about which OpenGraph tags Yoast SEO generates and outputs.

We output a variety of OpenGraph tags in the <head> of each page, in order to better inform data consumers about the content of the page in question. OpenGraph is consumed by Facebook, but also by Pinterest, LinkedIn, WhatsApp and even Google.
