WPML allows you to display content, which is written in the site’s default language, when viewing pages in other languages. If a translation exists WPML displays it, otherwise, it displays content from the site’s default language.
Let’s say you have a real estate site with properties. You want new properties to appear immediately in all languages, even though you haven’t translated them yet. Further, when displaying a property in any language, the site’s header, menu, and footer need to appear in that language.
As you can see, this feature is especially useful for listing sites, directory sites, membership sites and of course e-commerce sites.
The best part of using this translation mode is that it will have no negative SEO implications for your site.
WPML tells Google what is the original content, so Google can ignore all these duplicates. If you then actually translate a post or a page, Google will now see it as new content and not a duplicate.
To display original language content for all posts belonging to specific post types, go to the WPML -> Translation Management page and click the Multilingual Content Setup tab.
Scroll down to the Post Types Translation section and select the second option, Translatable – use translation if available or fallback to the original language, for all post types you need.
You can also enable this feature for taxonomies. In this case, if the taxonomies featured on a page are not translated, WPML displays the ones from the original names.
To display original language taxonomy values for specific taxonomies, go to the WPML -> Translation Management page and click the Multilingual Content Setup tab.
Scroll down to the Custom taxonomies section and select the second option, Translatable – use translation if available or fallback to the original language, for all post types you need.
The ability to display untranslated content on pages in secondary languages was introduced with WPML 3.9 version. In the preceding versions, you had to use content duplication.
When switching your site to new translation mode, you will want to start by removing all the duplicates in your site. You can find the detailed instructions on how to do this on the page about deleting duplicate content after changing how content is translated.
