twitter:description

The description shown beneath the title in X (Twitter) Card previews — falls back to og:description.

twitter:description appears below the title in summary and summary_large_image cards on X/Twitter. Maximum visible length is approximately 200 characters before truncation. Falls back to og:description if not explicitly set.

Write twitter:description as a short, compelling hook — something that makes the reader want to click. The X context is different from Google search: users are in a fast-scrolling, social-engagement mindset, so the tone can be more engaging and less formal than a meta description.

For viral-potential content (guides, tools, data), test different descriptions by looking at tweet engagement. The card description is often the deciding factor for whether someone clicks through from their timeline.
