Open graph is a protocol that allows web pages to become rich objects in a social graph. It is primarily associated with Facebook and enables websites to control the presentation of their content when shared on social media platforms.
Open Graph tags are meta tags added to the HTML of a webpage, providing information about the page's title, description, image, and other relevant details for a more visually appealing and informative social media sharing experience.
When a webpage includes Open Graph tags, sharing the link on Facebook can generate a preview that includes a specific title, description, and image, enhancing the content's visibility.
