WPML: Multilingual WordPress Websites — When It's Worth It

WPML stands for WordPress Multilingual Plugin and has been the most widely used plugin for multilingual WordPress websites for over 15 years. More than 1.5 million active installations worldwide — a figure that shows just how established the tool has become.

At its core, WPML does the following: it allows you to create each page, post, and menu item in multiple languages. Visitors see the website in their language, and each language version has its own URL — important for both SEO and user navigation.

For your SME, this means concretely: you don't need to run two separate websites to offer German and French. Everything runs through a single WordPress installation. That sounds more efficient than it often is — more on that shortly.

WPML delivers value where multilingualism goes truly deep — not just the homepage or a handful of subpages, but when content needs to be regularly maintained, updated, and managed across multiple languages.

Demand for WPML is high — but not every SME needs the full complexity of the plugin. In many projects, WPML ends up being used when a lighter-weight solution would have achieved the same goal with less maintenance overhead.

Before committing to WPML (or an alternative), it's worth honestly answering a few fundamental questions. This checklist helps you assess your own situation — independently of what your developer or an agency recommends.

The market for multilingual WordPress solutions is manageable: three approaches dominate, and all have their place. The choice depends less on feature lists than on your situation — team size, budget, maintenance effort, and technical support.

There is no objectively best plugin — only what fits or doesn't fit your project.

Weglot is a special case: it's not a traditional WordPress plugin but a cloud-based solution that stores and translates content externally. This makes setup simple — but vendor dependency and monthly costs can become relevant quickly as your website grows. If you cancel Weglot at some point, you lose all stored translations.

Multilingual websites and SEO are technically demanding — regardless of which plugin you use. WPML gives you the tools for a clean SEO structure, but it doesn't automatically configure them correctly. The responsibility lies in the setup.

The most important element is the hreflang attribute: it signals to Google which language version of a page is intended for which region. If it's missing, misconfigured, or inconsistently applied, Google interprets language versions as duplicate content — with negative consequences for the ranking of all versions.

WPML generates hreflang tags automatically, as long as language versions of pages are correctly linked. This works reliably, provided all pages are fully translated and the connections between language versions are maintained. A half-translated website with missing links generates incorrect hreflang tags that are difficult to debug.

Those using an SEO plugin like Yoast or RankMath alongside WPML need to verify both systems are sending the same signals. Conflicts between WPML-generated and SEO plugin-generated hreflang tags or canonicals are a common source of indexing problems — and are often underestimated by agencies. More on this in the CMS check for Swiss SMEs.

The licence fee is the most visible but rarely the largest cost factor with WPML. Anyone planning a multilingual website should keep the full picture in mind.

The licence costs approximately CHF 38 to CHF 192 per year depending on plan — for most SME projects, the Multilingual CMS plan (~CHF 96/year) is sufficient. It includes 90,000 automatic translation credits, which covers a medium-sized website for the initial setup.

The larger effort comes from setup and ongoing maintenance: configuring WPML correctly — with clean URL structures, hreflang configuration, compatibility testing with existing plugins and page builders — requires experience and time. For a typical SME website, 4–10 hours of development time for the base configuration is realistic, depending on complexity.

On top come translation costs: professional translations range from approximately CHF 0.10–0.20 per word depending on language and text length. A 20-page website with 500 words per page means 10,000 words — roughly CHF 1,000–2,000 for translation alone, without setup and maintenance. Automatic translations are cheaper, but require proofreading.

Factoring this in realistically leads to better decisions — regardless of which plugin is ultimately chosen.

Those who haven't yet committed to a platform have more flexibility than they realise. Whether WordPress is the right foundation for a multilingual website is a question worth asking before choosing a plugin.

Squarespace offers a native multilingual solution and a direct integration with Weglot — translations are managed in the cloud, without plugin dependencies or compatibility risks. For SMEs without an existing WordPress infrastructure, this is often the smoother path.

Webflow has had its own localisation features since 2023: separate URL paths, hreflang tags, and translatable components — all without external plugin dependencies.

Custom-built websites on modern platforms like Astro treat multilingualism as an architectural requirement — each language is a dedicated content path, planned from day one. No plugins, no compatibility issues, no hidden complexity during updates. More on this in the WordPress alternatives article.

This doesn't mean WPML is the wrong choice. For existing WordPress websites with high translation workloads and technical support in place, it remains a proven solution. But those who can still choose their platform freely should treat multilingualism as an architecture question — not a plugin question.
