Definition
Open Graph is a protocol created by Facebook (Meta) that defines how a web page is presented when shared on social media. Open Graph tags (og:title, og:description, og:image, og:url, og:type) are placed in the HTML head and control the title, description, image, and URL displayed in share previews on Facebook, LinkedIn, Pinterest, and other platforms. Although Open Graph does not directly affect SEO rankings, it improves social engagement and referral traffic by making shares more attractive.
