What does the Twitter / X Card check look for?
It checks for the Twitter/X Card meta tags that define your preview on X. Specifically:
- twitter:card — the card type, such as summary or summary_large_image.
- Card content — twitter:title, twitter:description and twitter:image (or the Open Graph equivalents X falls back to).
- Image suitability — whether the card image is present and appropriately sized for the chosen card type.
A twitter:card tag present passes; partial tags is a warning; none (with no usable Open Graph fallback) is a fail.
How is it evaluated, and how is it scored?
GEObubbly inspects the page's head for Twitter/X Card tags. It's an extended Structured Data check that runs directly against the page's markup.
Why Twitter / X Cards matter for SEO and GEO
Twitter/X Cards are the X-specific equivalent of Open Graph: a small set of meta tags that tell X how to render your link as a rich preview card. The twitter:card tag sets the type — summary for a compact card or summary_large_image for a prominent full-width image — and companion tags supply the title, description and image. Helpfully, X falls back to your Open Graph tags when the Twitter-specific ones are absent, so a page with good OG markup still previews reasonably on X. That fallback is why this is an extended rather than core check. Still, declaring an explicit card type — particularly summary_large_image — gives you precise control and the most eye-catching presentation when your content is shared on X, which can meaningfully improve engagement and click-through from the platform. Like Open Graph, it isn't a direct ranking factor, but it strengthens the social-sharing experience that drives discovery and reinforces consistent, on-brand previews across networks.
