Check your Open Graph tags for social sharing
Missing Open Graph tags mean broken previews when your links are shared on social media. SiteCurl checks every page for og:title, og:description, og:image, and Twitter cards.

What this check does
SiteCurl checks for four social sharing tags: og:title, og:description, og:image, and twitter:card. These tags control what people see when your link is shared on Facebook, LinkedIn, X, Slack, and other platforms.
Without these tags, shared links show a blank preview or pull random text from your page. With them, every shared link shows the title, description, and image you chose. The check reports which tags are present and which are missing.
Why it matters
Links shared on social media are free advertising. But a link with no image and a garbled title gets ignored. A link with a clear title, description, and eye-catching image gets clicked. Open Graph tags are the difference between the two.
This matters even more for B2B. When someone shares your link in a Slack channel or LinkedIn post, the preview is your first impression. A broken preview signals a site that is not well maintained.
How to fix it
Add these four meta tags to every page: og:title, og:description, og:image, and twitter:card. Most CMS platforms have fields for these in SEO or social sharing settings.
For og:image, use an image at least 1200x630 pixels. This size works well on all platforms. Make sure the image URL is absolute (starts with https://), not relative.
Set twitter:card to 'summary_large_image' for pages with a strong visual, or 'summary' for text-heavy pages. Test your tags with the Facebook Sharing Debugger and X Card Validator after adding them.

Frequently asked questions
What is Open Graph?
Open Graph is a protocol created by Facebook that controls how links look when shared on social media. It uses meta tags in your HTML to set the title, description, and image for shared links.
Do I need both Open Graph and Twitter Card tags?
Yes. Most platforms read Open Graph tags, but X (Twitter) prefers its own twitter:card format. Adding both ensures your links look good everywhere.
What size should my og:image be?
At least 1200x630 pixels. This size displays well on Facebook, LinkedIn, X, and Slack. Use an absolute URL starting with https://.
Can I check Open Graph tags without signing up?
Yes. The free audit checks for social sharing tags as part of a full seven-category scan. No signup required.
Why does my shared link show the wrong image?
Platforms cache Open Graph data. After updating your tags, use the Facebook Sharing Debugger to clear the cache. The new image will appear on the next share.
