What does your link look like when it is shared?
Paste it once and see the card WhatsApp, X, LinkedIn and Facebook will each build from it, before it goes to a group of four hundred.
Why it matters
A link with no card is a link nobody opens
- WhatsApp is the strictest, and it is the one that counts. It refuses any image over 300KB, so keep yours under that at 1200×630.
- Four tags decide all of it:
og:title,og:description,og:imageandtwitter:card. Most sites we check are missing at least one. - The scrapers do not run JavaScript. A tag added after the page loads is invisible to them, and to this tool, which is why the answer here is the honest one.
Next step
We can make every link look like this.
Preview cards are part of every site we build, and retrofitting them to one you already have is an afternoon rather than a rebuild.
