Twitter / X Card Checker

What this tool does

Reads twitter:* tags and tells you whether the card type, title and image are present or covered by Open Graph fallbacks.

Who should use it

Publishers who want correct previews on X.

How it works

The page is fetched and its meta tags parsed; known card types are validated.

How to use it

1. Enter the full address of the page or site, including https://.
2. Press the run button. The check makes live requests from our server and can take up to about 30 seconds.
3. Read the findings first, then open the tables for detail. Each finding has a severity and a suggested fix.
4. Copy or download the results if the tool offers it, fix the issues on your site and run the check again to confirm.

Practical example

A page with og:title/og:image but no twitter:card gets a recommendation.

Understanding the results

Fallbacks mean the card may still work without twitter-specific tags.

Limitations

This is a live check of the URL, made from our server; results can differ from what search engines or visitors see from other locations. This does not call X's card validator.

Accuracy and report transparency

Findings come from a real HTTP request made by our server. The result panel shows the checked URL, the UTC time of the check and the data source, and separates measured findings from limitations. We do not show random or sample metrics.

Privacy

The URL you enter is used only to make the request and is not stored in our database. Results may be cached for about ten minutes to limit repeat requests, and the checker blocks local and private network addresses. See the Privacy Policy.
