Open Graph metadata
og:url
Provides the canonical URL used as the object’s permanent identifier. It is one of the four required basic properties.
Code examples
Good example
<meta property="og:url" content="https://example.com/page.html">An absolute, canonical page URL.
Avoid this example
<meta property="og:url" content="/page.html">A relative path is not a canonical absolute URL.
Avoid this example
<meta property="og:url" content="https://example.com/different-page.html">Wrong when this URL identifies a different page rather than the current object.
Recommendations
- 01Always Use Absolute URLsInclude the scheme and host so every consumer identifies the same URL.
- 02Match the Canonical URLIf the page declares a canonical link, use the same URL here.
