⚙️Technical Specifications & Card Rendering Architecture
Major social platforms parse Open Graph (og:) and Twitter Card (twitter:) tags to synthesize link cards. Missing or misconfigured tags result in broken cards or missing thumbnails.
• Open Graph 1.91:1 Ratio: Evaluates 1200x630px high-resolution banner dimensions required for high-DPI displays.
• Twitter Large Image: Simulates 2:1 and 1.91:1 image card scaling on Twitter web and mobile clients.
• LinkedIn Feed Card: Previews standard 1200x627px feed snippet card layouts with truncated descriptions.
• Automated Tag Generation: Produces valid og:title, og:description, og:image, og:url, og:type, twitter:card, twitter:title, twitter:description, and twitter:image tags.
• 100% Client-Side Simulation: Executes entirely in browser memory without sending URLs or content to third-party scrapers.
Consistently previewing social cards guarantees high engagement, prevents missing image placeholders, and ensures brand consistency across networks.
