Check twitter:card and the related title, description and image metadata. When using Open Graph alongside it, keep the information consistent rather than supplying conflicting titles or images.
Verify supported card formats, image requirements and presentation against current platform documentation and actual sharing results. Do not present an old Card Validator preview workflow or unverified tag-precedence rule as current guidance.
If the preview differs from expectations, inspect server metadata, crawler access, the image URL and cache state. Card display is distinct from an actual site visit or inquiry.
