Twitter Cards are a set of meta tags that tell X (formerly Twitter) how to display your page when someone shares it - including which image, title, and description to show. These tags were not found on your site.
Why this matters
Without them, shared links on X may show as plain text with no preview image. Rich previews can make a shared link more eye-catching and may increase clicks.
How to fix it
Add a small block of meta tags to your page's head section starting with <meta name="twitter:card" content="summary_large_image">. Include a twitter:title, twitter:description, and twitter:image pointing to a high-quality image.
