Frequently asked questions

What is Open Graph metadata?

Open Graph tags describe the title, description, image, URL and content type that social platforms may use when a page is shared.

Does this tool fetch a live webpage?

No. Paste the page HTML source and it is parsed locally in your browser.

Which tags are most important?

A clear og:title, og:description, absolute og:image URL and canonical og:url form the core sharing card.

Why can a social platform show an old preview?

Platforms often cache metadata and images, so changes may require a platform-specific refresh or debugger tool.

Does the preview exactly match every social network?

No. Each platform crops images and truncates text differently; this is a practical content preview.

What is twitter:card?

It tells X/Twitter which card layout to consider, such as summary or summary_large_image.
