It checks the URL for the necessary Twitter meta tags—like `twitter:card`, `twitter:title`, `twitter:description`, and `twitter:image`—and renders a live preview so you can spot issues before you post ([socialpilot.co](https://www.socialpilot.co/blog/twitter-card-validator?utm_source=chatgpt.com "What is a Twitter Card Validator and How to Use it? - SocialPilot")). --- ## 🛠️ How to Use It 1. **Open the Validator** Visit the Twitter Card Validator on X’s developer site. 2. **Paste Your URL** Add the link for a page that includes Twitter Card meta tags (usually in the `` section) ([developer.x.com](https://developer.x.com/en/docs/x-for-websites/cards/guides/getting-started?utm_source=chatgpt.com "Getting started with Cards | Docs - Twitter Developer Platform"), [vistasocial.com](https://vistasocial.com/insights/twitter-card-validator/?utm_source=chatgpt.com "What is a Twitter Card Validator and How to Use It? - Vista Social"), [tweetdelete.net](https://tweetdelete.net/resources/twitter-card-validator-a-tool-to-increase-website-traffic/?utm_source=chatgpt.com "Twitter Card Validator: A Tool To Increase Website Traffic"), [socinator.com](https://socinator.com/blog/twitter-card-validator/?utm_source=chatgpt.com "What Is A Twitter Card Validator And How To Use it? - Socinator")). 3. **Check the Preview & Log** Click **Preview Card** (or **Check Preview**) to see how the card will render in a tweet.
