Social share preview

Enter a page address and see the card it makes when the link is shared, plus the Open Graph tags behind it and what is missing.

Free. Reads one page per check, the first 512 KB.

What a link looks like before anyone clicks

Slack, LinkedIn, X, iMessage: they all draw the same card from the same tags.

A share card as a messaging app draws it: the og:image on top, then the og:title, one line of og:description, and the domain from og:url.

When someone pastes your link, the app fetches the page and builds a card: an image, a title, a line of description, the domain. The page gets judged on those four things before anyone reads it.

The check fetches your page the same way those apps do and shows you the card they would draw.

Seven tags do most of the work

og:title, og:description, og:image, og:url, twitter:card, plus the page title and meta description.

The head tags behind a share card, one per row with a verdict: the title, og:title, and og:description are present; og:image uses a relative address; twitter:card is missing.

They live in the head of the page. A missing og:image turns the card into a plain text link. A long og:title gets cut mid-word. The checklist under the card names each tag, says whether it is there, and what to change.

It reads the HTML your server sends, so tags added by JavaScript after load will not show. Most sharing apps do not run JavaScript either, so that is the honest picture.

These are the first words people read

A typo in og:title travels with every share.

A fixes ledger: each row names the page or tag, quotes the flagged text, and gives the correction beside it.

The title and description in a share card are copy like any other, and the most exposed copy on the page. Verant proofreads them with the rest of the page and hands you the fix, quoted verbatim.

Frequently asked questions

Why does my link show no image?

Usually because og:image is missing, points at a relative path, or uses http on an https page. Add og:image with an absolute https URL to an image that exists, then re-share; some apps cache the old card for a day or more.

What size should og:image be?

1200 by 630 pixels is the size every major platform accepts, under 5 MB, as a JPEG or PNG. Keep the important part of the picture in the middle; some apps crop to a square.

Why does the preview differ from what Slack or LinkedIn shows?

Each app caches cards, so a tag you changed today may not show until the cache clears. Some apps also prefer twitter:* tags over og:* tags, or fall back to the page title when a tag is missing. The checklist shows which tags are actually present.

Does it read tags added by JavaScript?

No. It reads the HTML your server sends, which is what sharing apps read too. If your og tags are injected by a script after load, most cards will not see them; render them server-side.

Do I need twitter:* tags as well as og:* tags?

X reads og:* tags as a fallback, but it needs twitter:card to decide the layout; without it you get the small summary card. Add twitter:card with summary_large_image and let the og:* tags carry the rest.
