Run the Website Health CheckHow it works
We load the page like a social platform's crawler would, read its Open Graph and Twitter tags, and render the share card those tags produce: image, site name, title, and description. Missing tags are called out along with what platforms fall back to instead.
When to use this
Before you share a new page anywhere it matters — a launch, a campaign, a newsletter. And whenever a shared link shows the wrong image or none at all: the preview here shows what the tags actually say, not what a platform cached last week.
Frequently asked questions
What are Open Graph tags?
Meta tags that tell platforms — from social networks to chat apps — what to show when someone shares your link: og:title for the headline, og:description for the text, og:image for the picture. Without them, platforms guess.
Why does my link show the wrong image when shared?
Usually one of three things: no og:image tag (the platform picks a page image at random), a relative image URL some platforms drop, or a platform cache holding an old version. This tool shows what your tags say right now, so you can rule the first two in or out.
What size should my og:image be?
1200×630 pixels is the safe answer everywhere — big enough for large-card layouts on every major platform, and the 1.91:1 shape platforms crop toward. Keep important content centered, since edges may be trimmed.
