About this tool
When you share a link in a message or a post, the app shows a card with a title, a short description and a picture. Those come from Open Graph tags in the page’s code, like og:title and og:image. This checker reads them the way the apps do and shows what’s missing.
The usual fixes: give every page its own og:title and og:description, and an og:image about 1200 by 630 pixels on an https:// address. Apps keep a copy of the card for a while, so after a fix, a link you already shared may look the same until they check again. Your OneLink page sets these tags for you, and on Pro you choose the words and the picture.
