Control how your link looks when shared

When someone shares your page on X, the card that appears, its image, title and description, comes from meta tags in your page, not from the page content directly. This validator reads those Twitter Card tags and previews the card, so you can confirm a shared link will look right before it is shared.

Why the tags and the page can disagree

The card is built from dedicated meta tags, and those tags can be missing, wrong, or out of date relative to the page. A page can look perfect and still produce a broken card because its image tag points to a deleted file or its title tag was never set. Validating the tags directly catches the mismatch that you would otherwise only discover when a share looks wrong in public.

A first impression you only get once

A shared link with a proper image and a clear title earns clicks; one with no image and a truncated title gets scrolled past. Because the card is the first and often only thing people see of your page in a feed, getting the tags right is worth the check. The validator reads the tags and shows the resulting card. It runs in your browser.

Frequently Asked Questions

Where does the shared card come from?

From dedicated Twitter Card meta tags in your page head, not from the page content directly. The image, title and description are all specified there.

Why does my page look fine but the card broken?

Because the card is built from separate meta tags that can be missing or out of date, such as an image tag pointing to a deleted file, even when the page itself is correct.

What makes a good social card?

A valid image of the right proportions, a clear title and a concise description, so the link stands out in a feed rather than appearing as bare text.

Why validate before sharing?

Because the card is the first impression in a feed, and you only get it once. Catching a broken tag beforehand avoids a poor public share.

Is my input uploaded?

No. The validation runs in your browser.
