Open Graph Protocol & Social Share Specifications
The Open Graph protocol(created by Facebook) and Twitter Card tags enable webpages to become rich interactive graph objects in social feeds and messaging platforms. When users paste a link into WhatsApp, Facebook, LinkedIn, X, or Slack, the platform's crawler fetches Open Graph metadata to render a high-converting visual preview card.

Frequently Asked Questions
Why is Facebook or Twitter showing an outdated share image?
Social platforms aggressively cache Open Graph metadata for up to 30 days. Use the official Facebook Sharing Debugger or Twitter Card Validator to force crawlers to scrape the latest metadata.
Does WhatsApp support Twitter Card tags?
No. WhatsApp strictly parses og:image and standard HTML <title> tags. Twitter Card markup is ignored by WhatsApp.
