Why Twitter Cards Matter for Your Website
When you share a URL on X (formerly Twitter), the platform reads the meta tags in your page's HTML to generate a rich media preview card. A well-configured Twitter Card with a compelling image, a clear title, and a concise description can increase your click-through rate by up to 40% compared to a plain text link. This tool lets you preview exactly what users will see before you post.
