Social Share Preview Checker

When someone shares your website in a WhatsApp group or on Facebook, the preview card is your first impression — and a missing image or blank title quietly kills the click. This tool fetches any page’s Open Graph and Twitter card tags and shows you the card people actually see.

Any public page. We read it once, the way search engines do, and store nothing.

How to read it

Two of five tags are set, so a share on WhatsApp, LinkedIn or Facebook shows the practice name and a photo of reception, with no description and no canonical URL under it. The image is there, which is the tag people most often forget; og:description is the one that turns a link into a reason to click. The checker reports what is in the HTML; it does not fetch the image to confirm it exists or measure its size.

Meadowbank Dental is a fictional practice written for these examples: the result above is what this tool’s code produces on that page, regenerated whenever the site is built, and is not a real business’s data.

How it works

What this tool measures, and what it leaves alone

Read this before you act on a result. Every tool here states its method and its limits in the same breath.

The tags that control your share card

Four Open Graph tags do most of the work: og:title (the headline), og:description (the line under it), og:image (the picture — 1200×630 pixels is the safe size) and og:url. X/Twitter reads its own twitter:card tag to decide between a small summary and a large image card, falling back to Open Graph for the rest.

For a local business the highest-value fix is almost always the image: shares with a real, correctly-sized image get dramatically more attention than the grey placeholder card. Use a photo of your premises, team or work — not a logo on white.

Questions

Common questions

Why does WhatsApp show an old image after I fixed my tags?

Platforms cache share previews aggressively. Facebook’s Sharing Debugger has a "scrape again" button that refreshes its cache (WhatsApp uses Facebook’s crawler); for others, the cache typically expires within days.
