How does your link look when it's shared?
Paste a page. You see the preview card for WhatsApp, Facebook, LinkedIn and X, and a list of any tags that are missing.

- Reading Open Graph and Twitter tags
Why link previews matter
When someone shares your page on WhatsApp, Facebook or LinkedIn, the app builds a little card from tags hidden in your page: a picture, a title and a line of description. A good card gets tapped. A link with no picture looks like spam and gets ignored. These tags are called Open Graph tags, and X adds a few of its own called Twitter cards.
The tags you need
| Tag | What to put in it |
|---|---|
| og:title | A short, clear title, under about 60 characters. |
| og:description | One or two sentences with a reason to tap. |
| og:image | A full https address of an image, 1200 × 630 pixels, under 1 MB. |
| og:url | The page's own address. |
| twitter:card | summary_large_image, for a big picture on X. |
Most website builders and SEO plugins (Yoast, Rank Math, Shopify themes) have a "social" section where you set these without touching code.
Questions
Why does my link show no picture on WhatsApp or Facebook?
The page is missing an og:image tag, or the image is too small, too large or blocked. Add an og:image of about 1200 by 630 pixels, under 1 MB, at a full https address.
I fixed it but the old preview still shows.
Facebook, LinkedIn and WhatsApp cache previews. Use the Facebook Sharing Debugger or LinkedIn Post Inspector to refresh them. WhatsApp updates on its own, usually within a day.
What size should a share image be?
1200 by 630 pixels works everywhere. Keep text away from the edges, because some apps crop it into a square.
Is this the same as the Twitter card validator?
It does the same job. X removed its own card preview tool, so this shows how your link should look using the same twitter: and og: tags.
