What it does

When someone shares your page, the preview card is the first thing anyone sees: the image, the title, the line under it. If the tags behind it are missing or broken, you get a blank grey box or the wrong image.

Social preview checker fetches your page the way each platform’s crawler does and shows you the card each one will draw, so you can fix it before you share.

How it works

  1. Paste a URL.
  2. We fetch the page the way the LinkedIn, X, Slack and iMessage crawlers do and read its Open Graph and Twitter Card tags.
  3. You see the preview card each one will draw.
  4. Every missing, too-long or broken tag is listed with the reason it matters, and you get a ready-to-paste block of corrected tags for your page <head>.

Getting the most from it

  • Platforms cache previews. After you fix the tags, a link you already shared may keep the old card for a while.
  • Check your most-shared pages first: the home page, your offer and your latest article.
