Complete Guide to Twitter Cards

Most marketing pages, tools, and articles should use `summary_large_image`. It gives the link more room in the feed and makes the preview image worth testing. The small summary card can work for plain articles, but it usually feels weak when the image is part of the pitch.

If you are trying to get clicks, use the large card unless you have a specific reason not to.

Use `twitter:card`, `twitter:title`, `twitter:description`, and `twitter:image`. These tags let X know exactly how you want the card to render instead of forcing it to guess from the Open Graph fallback.

Keep the values consistent with your Open Graph tags. If one title says one thing and the other title says another, you are just creating another place for previews to drift.

Even if your Twitter Card tags are perfect, still keep `og:title`, `og:description`, and `og:image` accurate. Slack, Discord, LinkedIn, Facebook, iMessage, and plenty of other tools are going to look at the Open Graph tags first.

Think of Twitter tags as the platform-specific layer. Open Graph is the base layer that keeps the link from falling apart everywhere else.
