What it does
When you share a link and it shows a bare URL or the wrong picture, this finds why and gives you the fix. Your pages then show a proper card on Facebook, LinkedIn, X, WhatsApp, Telegram, Slack and Discord. It starts with the raw HTML to see which tags exist. Then it supplies a complete set of Open Graph and Twitter tags, with absolute image addresses. The image check covers 1200 by 630 pixels, a size under 8 MB, and public access with no login. It adds notes for each platform, because each reads tags a little differently. Finally it shows how to test with each platform's own preview checker.
