What is Open Graph

Hi,

I don’t know anything about Open graph in SEO. Please help me and tell me what is Open Graph and how can I use this and how it will help me in SEO and every thing related to Open graph.

Open Graph is Facebook’s latest development to allow for the [easier] publishing of activity and comments. There’s certainly potential SEO benefits but I wouldn’t consider this to be an SEO tactic as much as a social / engagement one.
