The best multilingual CMS for your business is the one that gives every language its own URL, supports hreflang, lets you translate everything visitors see (including menus, forms, product data and SEO fields), fits your team’s workflow and doesn’t force you to rebuild your site. For many businesses, that means keeping the CMS they already have and adding multilingual capability through a plugin, a built-in module or a website translation layer, rather than migrating to a new platform just for languages.

Key takeaways

• Multilingual support is either native (built into the CMS), plugin-based (added to the CMS) or external (a translation service in front of any CMS).
• WordPress has no built-in multilingual support and relies on plugins. Drupal ships multilingual modules in core. Shopify supports up to 20 languages per store (30 on Shopify Plus) with automatic hreflang, and Wix has Wix Multilingual.
• Whatever you pick needs one URL per language, hreflang, full coverage of on-page text, translated metadata, a language switcher, and an editing workflow your team will actually use.
• Changing CMS only to get multilingual features is rarely worth it. Check whether a plugin or translation layer covers your needs first.

What makes a CMS “multilingual”?

A CMS is multilingual when it can store, manage and publish the same content in more than one language, and serve each version correctly to visitors and search engines. A CMS can get there in three ways:

1. Natively, when the CMS itself stores translations and generates language URLs. Drupal core’s multilingual modules, Wix Multilingual, Shopify’s language settings and Webflow’s localization feature all work this way.
2. Through a plugin or extension that adds languages to a CMS without them. WordPress is the main example.
3. Through an external translation layer, where a website translation service detects the content your CMS publishes, translates it and serves each language on its own URL. The CMS itself stays single-language. This works with any CMS, including custom-built sites.

The checklist: what to evaluate

Ask these questions of every option.

SEO

• Does each language have its own URL? Google recommends separate URLs per language rather than switching language with cookies or browser settings (Google Search Central).
• Which URL structures are supported? Subdirectories (/de/), subdomains (de.example.com) or separate domains. See subdirectories vs. subdomains.
• Are hreflang tags generated automatically and correctly? Each version must list itself and all others, or Google ignores the tags (Google Search Central).
• Can you translate titles, meta descriptions, image alt text, slugs and structured data?
• Are translated pages included in the sitemap?

Coverage

• Does it translate everything visitors see: theme text, menus, footers, forms, pop-ups, emails, checkout, product variants, and text injected by third-party apps?
• What about dynamic content loaded by JavaScript?
• Can you exclude things that must not be translated (usernames, code samples, legal text you’ve had translated separately)?

Workflow

• Is machine translation built in, or do you bring your own engine?
• Can reviewers edit in context (seeing the page) or only in a list of strings?
• Does it support a glossary and translation memory?
• Are there roles and permissions for translators, reviewers and agencies?
• Can you import and export translations (CSV, XLIFF, TMX) so you’re not locked in?
• What happens when the source page changes: are translations flagged, updated automatically, or silently left out of date?

Operations and cost

• How is it priced: per word, per language, per locale, per site or per year?
• Does it slow the site down? Test page speed on translated pages, not just the source.
• Does it survive theme changes, plugin updates and redesigns?
• Does it support right-to-left layouts, if you need Arabic or Hebrew?

How popular CMSs handle multiple languages

The details below come from each platform’s own documentation, checked 28 September 2026.

WordPress

WordPress’s own documentation states that it “currently does not support a bilingual or multilingual blog out-of-the-box” (WordPress developer docs). You add languages with a plugin (such as WPML, Polylang or TranslatePress), with WordPress Multisite, or with an external translation service. The plugins work very differently: some store each translation as a separate post, others translate on the front end. Our guide to choosing a WordPress translation plugin compares the approaches, and ConveyThis for WordPress covers the translation-service route.

WordPress suits content-heavy sites and blogs, and it has the widest choice of multilingual plugins.

Drupal

Drupal’s multilingual guide (for Drupal 8 and later) is built around four modules: Language, Interface Translation, Content Translation and Configuration Translation. Multilingual support is part of Drupal’s architecture, not a bolt-on. It can do a lot, but it takes developer time to configure well.

It fits organizations with developers, complex content models and strict editorial workflows.

Shopify

According to Shopify’s help center, you can sell in up to 20 languages on the Basic, Grow, Shopify and Advanced plans and up to 30 on Shopify Plus. Shopify creates language URLs using subfolders or subdomains and adds hreflang tags automatically. Translations can be added with Shopify’s Translate & Adapt app, CSV import or third-party apps such as the ConveyThis Shopify app.

It works well for online stores that want languages managed alongside Markets, currencies and checkout.

Wix

Wix Multilingual is Wix’s built-in language feature. Wix’s help center says you can auto-translate site content into over 130 languages, with additional word-credit packages (3K, 10K or 50K words) available to buy (Wix help center).

It makes most sense for small business sites already on Wix.

Webflow

Webflow offers a native localization feature for managing locales and translated content inside Webflow. Check Webflow’s current plans for locale limits and machine translation options, or use a translation service on Webflow.

It is aimed at design-led marketing sites built in Webflow.

Headless CMSs

Headless platforms typically let you define locales in the content model and return localized content through the API. The front end (often React, Vue or Next.js) is then responsible for routing, hreflang and the language switcher. You get a lot of control, but multilingual SEO becomes your development team’s job. This route fits product teams with engineers who want that control.

Should you switch CMS for multilingual support?

Usually not. A CMS migration touches design, content, URLs, redirects, integrations and team training, and it carries real SEO risk. Before you consider it, ask:

1. Can a plugin or built-in module on your current CMS meet the checklist above?
2. Can an external website translation service meet it without changing the CMS at all?
3. Is your CMS limiting you for other reasons too? If so, multilingual needs can feed into a migration decision, but they should not be the only reason for it.

If you do migrate, plan the URL structure for every language from day one and keep redirects from any old language URLs.

The external translation layer option

An external translation layer is often the fastest path to a multilingual site because it works the same on any CMS. ConveyThis works this way:

• You install it once: a WordPress plugin, a Shopify app, or one script tag for other platforms; there are 35 integration guides, including Wix, Webflow, Squarespace and custom sites.
• It translates all visible content automatically into any of 210 languages, including theme and app text, as a first draft.
• Each language gets a URL as a subfolder, subdomain or ?lang parameter (second-level domains on the Extreme plan), with automatic hreflang and translated meta titles, descriptions and JSON-LD.
• For editing and control there is a visual editor for in-context changes, a glossary, translation memory, exclusions for content that must stay untranslated, and team roles for reviewers.
• You can import and export translations as CSV or TMX.
• Pricing is based on translated words actually shown to visitors (bots don’t count), with plans by number of languages and sites. See pricing.

If your team works in several systems (a WordPress blog, a Shopify store and a custom app, for example), one translation layer across all of them keeps terminology and workflow consistent.

FAQ

What is the best CMS for a multilingual website?

There is no single best. Drupal has multilingual modules in core, Shopify handles languages natively for stores, and WordPress relies on plugins. The best choice is the one that meets the SEO, coverage and workflow checklist above on the platform your team already uses.

Does WordPress support multiple languages?

Not out of the box. WordPress’s documentation says it does not support multilingual sites natively; you need a plugin, Multisite, or an external translation service.

What is CMS translation technology?

It’s any method a CMS uses to store and serve content in multiple languages: native modules, plugins, or an external translation layer that translates the published pages.

Do I need a new CMS to translate my website?

Usually not. Most CMSs can be made multilingual with a plugin, a built-in feature or an external translation service, without migrating.

How do multilingual CMSs handle SEO?

Good setups give each language its own URL, add hreflang tags, translate metadata and include translated pages in the sitemap. Check each of these before choosing.
