Problem: The client is trying to generate separate sitemaps for each language on their site using WPML Multilingual CMS, WPML String Translation, and Yoast SEO, with the URL format set to different languages in directories. However, they encountered an issue where all URLs for every language are combined into a single sitemap, and duplicate URLs appear in the page-sitemap.xml. Solution: We explained that the current setup with WPML and Yoast SEO inherently generates one sitemap for all languages, which includes URLs from all languages. To achieve separate sitemaps for each language, the client would need to switch to the domain per language mode. This setup allows for individual sitemaps per language domain.
