How to use this Open Graph checker and Twitter card validator

Use it as an open graph tester and og image checker in one step: paste a URL and the tool reads its og: and twitter: tags straight from the live HTML, then renders preview cards the way each network would. If a preview looks wrong here, it will look wrong in people's feeds.

Paste the full URL of the page you want to check.
The tool fetches the og: and twitter: tags from the live HTML.
Review the Facebook, LinkedIn, and X preview cards and fix anything the checks flag.

The most common fixes: add an og:image with an absolute URL at 1200x630, keep og:title under 60 characters, and set twitter:card to summary_large_image.

Which platforms use Open Graph tags

Open Graph tags drive link previews across Facebook, LinkedIn, X, WhatsApp, Slack, Discord, Telegram, Pinterest, and Reddit. Most read og:title, og:description, and og:image; X also honors its own twitter: tags and falls back to Open Graph when they are missing.

The key Open Graph tags

og:title is the headline shown on the share card.
og:description is the summary line under the title.
og:image is an absolute URL to a 1200x630 image.
og:url is the canonical URL of the page.
og:type is usually "website" or "article".

Frequently asked questions

What is an Open Graph checker?

It fetches a URL and reads its Open Graph and Twitter card tags, the metadata Facebook, LinkedIn, Slack, and X use to build the link preview card, then shows you exactly what each network will render.

Why does my link show no image when shared?

Usually the page is missing an og:image tag, the image URL is relative or broken, or the image is too small. Networks want an absolute URL to an image at least 1200x630 pixels.

What size should an og:image be?

Use 1200x630 pixels (a 1.91:1 ratio). That renders sharp on Facebook, LinkedIn, and X large-card previews without cropping surprises.

Do I need separate Twitter card tags?

X falls back to Open Graph tags for most fields, but you should still set twitter:card to summary_large_image, otherwise shares can render as a small thumbnail card.

Do Open Graph tags help with SEO?

Indirectly. Open Graph tags do not change rankings on their own, but better share previews lift click-through and engagement on social, which can drive the traffic and links that do support SEO.
