Starke SEO ohne Social Preview

Social preview cards control how your links appear when shared on Twitter/X, LinkedIn, Slack, Discord, iMessage, and dozens of other platforms. Without Twitter Card markup, shared links show a plain URL or an unpredictable auto-generated preview that rarely represents your brand well. For sites that already rank well in search, social sharing is often a significant secondary traffic channel — and poor previews directly reduce click-through rates on shared links. The standard implementation requires just four meta tags: twitter:card (usually "summary_large_image"), twitter:title, twitter:description, and twitter:image. These should be aligned with your existing Open Graph tags (og:title, og:description, og:image) for consistency. Most CMS platforms and frameworks have plugins or built-in support for these tags. The twitter:image should be at least 1200x628 pixels for large image cards. Testing is straightforward using Twitter's Card Validator or by simply pasting a URL into a Twitter/X compose window.
