When someone shares your URL on Facebook, LinkedIn, X, or Slack, the platform reads your Open Graph meta tags to build the preview card. Missing or broken OG tags result in a blank card or a random snippet of text — which means fewer clicks.
The most important tags: og:title, og:description, and og:image (minimum 1200×630px). Add twitter:card with value summary_large_image for X.
SEOLint checks Open Graph, Twitter Cards, and 40+ other issues automatically.
