How to check your share previews
- Open your page in the browser and view its source (Ctrl+U, or ⌥⌘U on a Mac).
- Copy everything and paste it above. Only the <head> part is needed.
- See how the link will look on Facebook, X, LinkedIn and WhatsApp, and fix anything marked red.
Writing the tags from scratch? Use the meta tag generator.
Frequently asked questions
Why paste the HTML instead of a link?
Browsers don't let one website read another website's pages, so a tool that runs in your browser can't fetch your page itself. Open your page, view its source (Ctrl+U, or ⌥⌘U on a Mac), copy it all and paste it here. Nothing is sent anywhere.
Which tags matter most?
og:title, og:description, og:image and og:url, plus twitter:card set to summary_large_image for a big picture on X. Use a full URL (starting with https://) for og:image, and a picture of 1200 × 630 pixels.
I fixed my tags but the old preview still shows. Why?
Social networks keep a copy of each link's preview for days. Ask them to read it again with Facebook's Sharing Debugger or LinkedIn's Post Inspector; X refreshes on its own after a while.
