Frequently Asked Questions

Why isn't my Twitter Card showing?

Twitter caches cards. After making changes, use Twitter's Card Validator at cards-dev.twitter.com to refresh the cache. Also ensure your site isn't blocking Twitter's crawler (Twitterbot).

Will Twitter use my Open Graph tags?

Yes, if Twitter-specific tags are missing, Twitter will fall back to OG tags (og:title, og:description, og:image). However, for best results, set both Twitter Cards and OG tags explicitly. Use our Open Graph Checker to validate your OG tags.

What's the difference between twitter:site and twitter:creator?

twitter:site is your website's official Twitter account (e.g., @YourBrand). twitter:creator is the content author's personal Twitter account. Both help with attribution.

Do I need to whitelist my domain?

No, Twitter removed the whitelisting requirement. Standard summary and summary_large_image cards work automatically. Player cards still require approval.
