Problem: Google not indexing translated sites Solution: Please visit WPML>>Languages, scroll down to *Browser language redirect* and check you are using *Always redirect visitors based on browser language* option. If so, it may be affecting how Google indexes your pages. Please check the following documentation for more details.
Visit WPML>>Languages, click on *Edit Languages* link of *Site Languages* section. Then share me the screenshot of *Edit Languages* page for a better understanding of your language settings.
