Ahrefs reported “Open Graph URL not matching canonical” error indicates a mismatch between the canonical URL and the Open Graph URL within a webpage. Ideally, both URLs should be identical for every webpage on your site.
- Canonical URL: This specifies the preferred version of a webpage, used by search engines and other systems to avoid duplicate content issues.
