How to Optimize Your Social Preview

When you share a link on Facebook, Twitter, or LinkedIn, they look for specific "Open Graph" (OG) tags in your HTML to decide what to display. If these tags are missing or incorrect, your link might appear as a plain URL, significantly reducing engagement.

Essential Tags Checklist

og:title: The headline of your content (Keep it under 60 characters).
og:description: A brief summary (Keep it under 110 characters).
og:image: The visual hook. Recommended size is 1200x630 pixels.
og:url: The canonical URL of the page.

Debugging Tips

If your image isn't showing up even after adding the tag, ensure the URL is absolute (starts with http/https) and publicly accessible. Localhost images won't appear on real social platforms, but our "Paste HTML" tool lets you simulate it!
