Open Graph, widely known as OG, is a Facebook resource that provides developers with a way to link Facebook features to their existing websites and applications. This feature makes a significant difference because it does not miss out on any important user information. By using open graph technology, you can easily embed social media into your websites. 

The OG protocol is used as an efficient marketing technique by social media marketers. Website owners can choose the title, image, and description according to their requirements to display it on the social media channel. Facebook is the most common social media platform that integrates the open graph protocol to be linked on any website.
