How to use it
- Copy the page HTML, including its full head.
- Paste it into the tool.
- Review which Open Graph and Twitter Card tags were found and how the card would look when shared.
What it works out and how
The tool pulls og:title, og:description, og:image and og:url from the HTML, along with their Twitter Card counterparts, and builds a preview of the card. It flags the missing ones, which is the usual reason a link gets shared with no image or a generic title.
Frequently asked questions
What size should the image be?
The usual reference is 1200 by 630 pixels, with a ratio close to 1.91:1. That way it shows large and uncropped on most platforms.
I changed the image and the old one still shows. Why?
Social networks cache the card. You have to force a fresh read with each platform's debugging tool.
Do I need Twitter tags if I already have Open Graph?
X falls back to Open Graph when its own tags are missing, but twitter:card is still needed to choose the large-image card format.
