The Social Media Link Preview Tool is essential for content marketers and developers. When you share a link on WhatsApp, Slack, or Twitter, a "Card" appears with an image and description. If this card looks broken, people won't click.

This tool scrapes your URL just like a social bot would and reconstructs the preview card. It allows you to verify that your Open Graph tags are set up correctly before you launch a marketing campaign.

Key Tags to Check

  • og:image: The most important visual element. Ideally 1200x630 pixels.
  • og:title: The headline of your snippet. Keep it under 60 characters.
  • og:description: A short summary (2-4 sentences) enticing users to click.

Frequently Asked Questions

Why doesn't my image show up on Facebook?

Common reasons include: the image is too small (should be at least 1200x630px), the `og:image` tag is missing, or the server is blocking the Facebook crawler.

I updated the image, but the preview is old.

Social networks cache previews for days. You need to use the official 'Card Validator' or 'Sharing Debugger' from Facebook/Twitter to force them to clear their cache.
