Problem: You are experiencing issues with duplicate content, titles, and meta descriptions appearing in SEO scrapes due to the WPML setting 'Translateable if exist, in other cases fallback to original language'. This setting causes untranslated content to appear as duplicate in SEO tools like SEMRush, and the correct canonical tags are not set. Solution: This behavior is expected as it prevents penalties for having the same content in multiple languages. WPML informs Google about the default content, allowing Google to ignore duplicate content on secondary language pages. Once you translate the content into the secondary language, it will no longer appear as a duplicate. We recommend using Google's tools to check this, as third-party tools may show different results. For more information on displaying untranslated content, visit Displaying Untranslated Content on Pages in Secondary Languages.
If this solution does not apply to your case, or if it seems outdated, please open a new support ticket. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins.
