Optimize Your Social Sharing
Why Preview Matters
Every platform renders metadata differently. WhatsApp favors small previews with specific aspect ratios, while X (Twitter) supports both small 'summary' cards and large 'summary_large_image' cards. Facebook uses a standard 1.91:1 ratio for link previews. Previewing your site allows you to ensure your branding is consistent and your call-to-action is clear across all apps.
CORS Proxy Technology
Fetching metadata from external websites directly in the browser is usually blocked by Cross-Origin Resource Sharing (CORS) policies. Our tool uses a centrally defined, high-performance proxy to bypass these restrictions securely, allowing you to debug any website's SEO health instantly.
