og:url

The canonical URL of the page for social sharing — used to aggregate share counts across URL variations.

og:url specifies the canonical URL for Open Graph purposes. Social platforms use this URL to aggregate all social engagement (likes, shares, comments) for the same piece of content regardless of which URL variation is being shared. Without og:url, sharing the same content from different URLs (with/without www, with tracking parameters) splits engagement counts.

Set og:url to the same value as your canonical URL — the clean, parameter-free URL without session IDs or tracking codes. This ensures all social proof aggregates to a single URL and you can consistently track social engagement in analytics.

Facebook is particularly attentive to og:url. When you submit a URL to the Sharing Debugger, Facebook normalises shares to the og:url value. LinkedIn and Twitter/X also reference og:url but are more lenient about URL canonicalisation.
