Why Twitter Card Previews Matter
When you share a link on X (formerly Twitter), the card preview is what makes your tweet stand out in a crowded feed. A well-crafted card with a clear title, description, and large image gets significantly more engagement than a plain URL.
X is unique among platforms in preferring twitter:card tags over Open Graph tags. If you only set og: tags, X may not render your card correctly.
