They also need ways for crawlers and tools to clearly identify and verify the language versions. TranslatePress is pleasantly pragmatic: A page remains a WordPress page, and the language versions are located in directories such as /en/, /fr/, or /it/. For editorial and operational purposes, this is often exactly the right approach. The technical side issue comes up later: How do you actually verify which URLs for a given language are included in the sitemap? This is exactly where Language Sitemaps for TranslatePress came into being. The plugin isn’t a new SEO promise and doesn’t replace Rank Math. Its scope is intentionally narrower: TranslatePress sites using Rank Math that require a separate sitemap index for each published language. The Short Version A sitemap does not guarantee indexing or rankings. However, it helps make important URLs discoverable and verifiable. For multilingual WordPress sites, the question isn’t just: „Is there a sitemap?“ The better question is: „Can I view each language version as its own URL group, check it, and use it for warm-up if needed?“ Language Sitemaps for TranslatePress adds indexes such as sitemap_index_en.xml and child sitemaps such as sitemap_en_post_1.xml. The standard Rank Math index, sitemap_index.xml, remains unchanged. How to Tell If This Applies to You You use TranslatePress with language directories and Rank Math for your XML sitemaps. So, for example, your website has German content under /, English content under /en/, and perhaps other languages under their own directories. This quickly raises some practical questions: Which English URLs are actually being submitted as sitemap paths right now? Is there a separate entry point for the English version? Can I check robots.txt to ensure the language indexes are visible? Can a cache warm-up specifically retrieve the English URLs? Does an additional language index still comply with the Rank Math rules? So the problem isn’t that language versions would be invisible without this plugin. That would be too simplistic and incorrect in many setups. TranslatePress SEO Pack and other SEO plugins can supplement multilingual sitemaps. The point here is more specific: creating separate, simple, language-specific indexes for TranslatePress directory URLs that don’t replace Rank Math, but rather complement it. What the plugin specifically adds Language Sitemaps for TranslatePress reads the published languages from TranslatePress and generates separate XML sitemap indexes for them. For English, for example, this might look like this: /sitemap_index_en.xml This index then points to child sitemaps for each content type or taxonomy: /sitemap_en_post_1.xml /sitemap_en_page_1.xml /sitemap_en_product_1.xml The Rank Math root index remains in place. This is important because Rank Math continues to serve as the central SEO sitemap layer. The plugin doesn’t add a second set of SEO logic; instead, it mirrors the relevant Rank Math rules: deactivated post types and taxonomies, global noindex rules, `rank_math_robots` on individual pieces of content, and `items_per_page`. Why robots.txt and Warmup Play a Role Here Sitemaps aren’t just useful for Google. They also serve as an operational signal: Which URLs should tools see, check, or prepare? The plugin automatically adds the language indexes to robots.txt. This makes it clear which language sitemaps are available. For setups with NitroPack, there’s also a dedicated warmup index: /nitro-warmup-sitemap.xml The WP-CLI command `wp localized-sitemaps sync-nitro` sets up this warm-up index in NitroPack. And with `wp localized-sitemaps list-indexes`, you can quickly check the available endpoints without having to click through XML files in your browser. What it deliberately does not do The plugin addresses exactly one specific technical use case (see above). It does not insert hreflang annotations into XML sitemaps. It is not intended for setups with separate domains per language. It does not support every special Rank Math provider, such as author, news, or video sitemaps. It does not promise better rankings. If you have a setup that already provides exactly the sitemap structure you need, you probably don’t need this plugin. However, if you use TranslatePress directory URLs and want clear, separate indexes for each language, that’s exactly what this plugin is for. Why I built it The specific reason was the English rollout of a client’s website. The site uses TranslatePress, Rank Math, and NitroPack. For operations, it wasn’t just important to know whether content was translated, but also whether the English URLs were visible as a separate technical group and capable of being crawled. In the live setup, `sitemap_index_en.xml` generates six English child sitemaps: Posts, Pages, Products, Coaches, Skills, and Workshops. The robots.txt file promotes the English language index. The standard Rank Math index remains unchanged. This isn’t a spectacular list of features, but rather the kind of small-scale infrastructure that makes a multilingual WordPress site easier to test. How to Check Your Setup If you’re using TranslatePress and Rank Math, I’d recommend checking the following in this order: Open your regular Rank Math sitemap. Check whether you can see the language versions clearly separated. Check your robots.txt: Which sitemaps are listed there? If you’re using cache warmup: Check which URL list the warmup is using. Check whether noindex content remains excluded from additional sitemaps. After that, you’ll have a better idea of whether you even have a problem. If so, Language Sitemaps for TranslatePress is a very small, targeted solution. Download The plugin is free and open source.
