How to fix og url mismatch on WooCommerce

Steps for WooCommerce

1. Install or open the Yoast SEO or Rank Math plugin (both handle og:url automatically on a per-page basis — this is the recommended fix path for WooCommerce).
2. In Yoast SEO: go to WordPress Admin → SEO → Social → Facebook tab and ensure 'Add Open Graph meta data' is enabled. Yoast will then output the correct og:url automatically on every page.
3. In Rank Math: go to WordPress Admin → Rank Math → General Settings → Social Meta and ensure 'Open Graph Meta' is ON.
4. If you are NOT using an SEO plugin and og:url is hardcoded in your theme's header.php or functions.php, locate the echo or printf statement outputting og:url and replace the static value with the dynamic <?php echo esc_url(get_permalink()); ?> (see code snippets).
5. After saving, use 'View Source' on a product, a category, and a post to confirm each shows its own URL.
6. Clear any caching plugin (WP Super Cache, W3 Total Cache, WP Rocket) after making changes.

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.
