Previews

Drawn after how each app showed a link in October 2026; each changes its look from time to time. An app may keep the card it drew first: LinkedIn's Post Inspector and Facebook's Sharing Debugger fetch it again.

Can they reach it

To fix: Asked as Facebook's crawleranswered 403

A firewall or a rule against bots stops this app's fetcher, so it draws no card.

Then, who comes from them

When the link is shared, tidekeeper counts who comes from each app, X, LinkedIn, Slack or a newsletter, with no cookie and nothing kept on their device.

How it works

Give an addressAny public page. Its HTML is fetched once, and the image it names.
See every app's cardDrawn as WhatsApp, iMessage, Google Messages, X, LinkedIn and the rest draw a shared link.
Fix what is cut or missingEach check that is worth a look says why, with the line to put in the page's head.

Questions

Why does my link show no image in WhatsApp?

WhatsApp draws the og:image only when it can fetch it: the tag must hold a whole https:// address, the image must not be too heavy, and the server must let WhatsApp's fetcher in. The diagnosis checks each of them, and asks the page as WhatsApp does.

How do I see what my link looks like in iMessage?

Give the page's address above: the iMessage card is drawn as it sits in a conversation, with the image, the title and the domain. iMessage shows no description.

What size should an og:image be?

1200 × 630 pixels, a shape of 1.91 to 1, which X, LinkedIn, Facebook and Google Messages draw large. A smaller image is drawn small, or soft.

Why does Facebook or LinkedIn still show an old card?

They keep the card they drew first. Facebook's Sharing Debugger and LinkedIn's Post Inspector fetch the page again.

Do you keep the pages I check?

No. The address is fetched when you ask, and is not kept. No cookie is set and no account is needed.
