Include custom canonical posts in the Rankmath sitemap

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

If you have set up a custom canonical URL in Rank Math, then those URLs won’t be included in the sitemap by default:
https://rankmath.com/kb/url-not-in-sitemap/#custom-canonical-url

However, if you wish to add them manually to your sitemaps, you can use the filter available here: https://rankmath.com/kb/filters-hooks-api-developer/#add-extra-urls-in-sitemap

/**
 Filter to add extra URLs to the XML sitemap by type.
 *
 Only runs for the first page, not on all.
 *
 @param string $content String content to add, defaults to empty.
 */
add_action( 'rank_math/sitemap/{$type}_content', function() {
return '<url>
<loc>https://rankmath.com/some-custom-url/</loc>
<lastmod>2023-06-10T20:20:20+00:00</lastmod>
</url>';
});

Then, replace {$type} with the type of sitemap you have (post, page, etc.).

Hope that helps.

Thank you.
