How to fix og url mismatch on WordPress.org

Steps for WordPress.org

1. Install Yoast SEO or Rank Math if not already present (both output a correct per-page og:url automatically).
2. In Yoast SEO: WordPress Admin → SEO → Social → Facebook → enable 'Add Open Graph meta data' and save. No further action needed — Yoast handles og:url dynamically.
3. In Rank Math: WordPress Admin → Rank Math → General Settings → Social Meta → enable 'Open Graph Meta' and save.
4. If you are managing og:url manually in your theme's header.php or functions.php, find the line echoing og:url and replace it with: <meta property='og:url' content='<?php echo esc_url(get_permalink()); ?>' />
5. If two sources are outputting og:url (e.g. your theme AND an SEO plugin), you will have duplicate tags — disable the theme's output to let the plugin take control (theme documentation will describe a filter hook to disable its social meta).
6. Clear caching plugins and verify with 'View Source' on several page types.

What is og url mismatch?

The `og:url` tag is a small piece of HTML in your page's `<head>` that tells social networks, messaging apps, and AI systems the "true" address of a page when someone shares it. When this tag is missing or set to a site-wide default (for example, always pointing to your homepage), every single page on your site tells the world it lives at the wrong address. A correct `og:url` should always equal the canonical URL of the exact page it appears on — never a template value, never your homepage, never an alternate URL.

When `og:url` mismatches the canonical URL, shares on Facebook, LinkedIn, Slack, WhatsApp, and other platforms create links that point to the wrong page — sending potential customers somewhere they didn't expect, or even to a 404. AI tools that cite your content (ChatGPT, Perplexity, Bing Copilot) read Open Graph data to form citations; a wrong `og:url` means citations and backlinks generated from shared content point to the incorrect URL, splitting your link equity and diluting your rankings. For ecommerce specifically, a product link shared by a happy customer that resolves to the homepage instead of that product costs you direct conversions. Search engines also use Open Graph data as a consistency signal; persistent mismatches can reduce crawl trust in your canonical declarations.
