The Open Graph protocol is a markup that you can add to your HTML documents in order to logically structure your content and gain control over the fragments that are displayed when your URLs are published via social networks such as Facebook, LinkedIn, Twitter, VKontakte , Odnoklassniki and applications such as Slack, WhatsApp, Viber and Telegram .
Why should you care about using Open Graph?
The presence of an attractive image that catches your attention, as well as a catchy and informative name and description , encouraging people to click on your fragment, significantly increase traffic to the site if you want to use traffic from social networks. Thus, the Open Graph layout allows you to easily control the display of fragments of your URLs on social networks.
Social activity is a great way to prove to search engines that you have high-quality content that can be shared, unique and valuable to a wide audience. Of course, Open Graph does not increase the site’s rating directly, but it helps search engines to determine the context of your content, just like Schema.org.
In the end, all other things being equal, your SEO performance really benefits from using Open Graph microdata more than without it.
