OG CHECKER

Check how your link looks on Twitter / X

Twitter (now X) uses a combination of twitter:card meta tags and Open Graph fallbacks to build link previews. A summary_large_image card dominates the feed with a wide image, while summary shows a small square thumbnail. Getting these right is the single highest-leverage change you can make for click-through rate on X.

How Twitter / X Renders Link Previews

When someone shares a link on X, the Twitter crawler (Twitterbot/1.0) fetches the page and reads meta tags in this priority order:

  1. twitter:card — determines the card type (summary, summary_large_image, player, or app).
  2. twitter:title — the bold headline. Falls back to og:title, then <title>.
  3. twitter:description — the subtitle text under the title. Falls back to og:description.
  4. twitter:image — the preview image. Falls back to og:image. Must be an absolute URL.

Twitter aggressively caches cards. Once a URL is scraped, the card is stored for roughly 7 days. The official Card Validator has been deprecated by X. Use Rediate to preview your Twitter cards instead, or check our Twitter Card Validator alternative for more details.

Twitter / X OG Tag Tips

  1. 1Always set twitter:card to summary_large_image for maximum visual impact in the feed. The small summary card is easily scrolled past. Learn the differences in our OG tags vs Twitter Cards guide.
  2. 2Keep your twitter:title under 70 characters. X truncates titles aggressively on mobile, often cutting at 55-60 characters.
  3. 3Use images with a 1.91:1 aspect ratio (1200x628). Images outside this ratio get cropped from the center, which can cut off logos or key text.
  4. 4Twitter strips EXIF data and re-compresses images. Export your OG images as PNG for text-heavy graphics or JPG at 85%+ quality for photos to survive re-compression well.
  5. 5Add twitter:site (your brand handle) and twitter:creator (the author handle). These add attribution links on the card and help with brand discovery.
  6. 6If you update your OG image, append a cache-buster query string (e.g., ?v=2) to the image URL or use the Card Validator to force Twitter to re-scrape.
  7. 7Avoid images smaller than 300x157 px — Twitter will silently drop them and show a text-only card instead.
  8. 8Do not use animated GIFs as your OG image. Twitter renders only the first frame, which is often blank or an awkward mid-animation state.
