Twitter Card Checker
Score whether X can unfurl a real card type, title, description and image — not a ranking trick.
What this tool gives you
Check Twitter Card tags
Fetch a public page or paste the head. The checker scores X/Twitter unfurl hygiene — not ranking folklore.
What this checker looks for
Twitter Card tags fill the X preview. They do not make ChatGPT cite you.
twitter:card
summary_large_image for tools and articles.
twitter:title
Name the page, not only the brand.
twitter:description
One sentence that says the job.
twitter:image
Absolute https 1200×630 image.
twitter:site
Optional @handle for the brand.
og:* fallback
X can reuse Open Graph if twitter:* is missing.
How to use the checker
Set the card type first. A pretty og:image on the wrong twitter:card still crops badly.
Check the live page
Fetch the public URL or paste the head from view-source.
Name card, title, image
summary_large_image plus an absolute https 1200×630 image.
Recheck after theme changes
CMS plugins overwrite twitter:* silently. Re-run after launches.
What a healthy Twitter Card usually includes
Card type. Title. Description. Absolute HTTPS image. Optional @handle. og:* only as fallback.
| Part | Job | Default for public sites |

Twitter Card FAQs
Does a Twitter Card make ChatGPT cite my page?
No. twitter:* tags fill X, iMessage and some Slack unfurlers. Citations still depend on crawl access, answer-ready content and corroboration.
Do I still need twitter:* if I have Open Graph?
X can fall back to og:title, og:description and og:image. Set twitter:card to summary_large_image anyway so the card type is explicit, then add twitter:image for large cards.
What size should twitter:image be?
Use 1200×630 for summary_large_image, absolute https, under about 5 MB. Relative /og.png paths often fail on X.
