To automatically translate a WordPress website, use a multilingual plugin or hosted translation service: choose your target languages and URL format, enable its automatic translation workflow, then review translations before publishing. WordPress’s site language setting does not translate your public pages. The exact automation, publishing controls, content coverage, and costs depend on the product and configuration.

What automatic translation does—and does not do

WordPress distinguishes software localization from translating a site’s public content. Its developer handbook describes localization as translating and adapting text and settings for another language and culture; changing the WordPress interface language alone does not translate your pages, posts, navigation, or store content. See the WordPress localization handbook.

A multilingual plugin or service adds a workflow for translated content. Depending on the tool, it may translate existing material, handle newly published or edited content, provide language-specific URLs, or send translations through editorial review. Do not assume every visible string or extension is covered: confirm support for your theme, forms, ecommerce features, and other plugins.

Choose a translation workflow

There is no universally best option. The sources below document different workflows, but do not provide an independent comparison of translation quality, speed, or total cost.

Option What the documentation establishes Check before choosing
WPML Its setup wizard covers languages, URL format, AI engine, and translation mode. It documents automatic translation of new posts, pages, and products as they are published when Translate Everything Automatically is enabled. New activations need the PTC engine for that mode. Confirm engine and language support, eligible content types, review and publishing controls, and the current displayed cost. WPML distinguishes billing for automatic and manual sends; check its current terms.
Weglot Its WordPress plugin connects to a Weglot account and supports automatic translation with translations presented for review before publication. Its listing documents language-specific URLs, hreflang tags, and translated metadata. Check supported languages, content limits, URL options, review controls, and current subscription terms. Translations are hosted on Weglot’s servers; if the service is discontinued, the site will no longer be translated through Weglot. The listing describes an export option.
Polylang Its WordPress.org listing documents a setup wizard and language-switcher blocks. The listing reviewed here does not establish that the free plugin itself automatically translates content. Find out whether the workflow is manual or requires a separate machine-translation integration, and verify compatibility and current requirements.
TranslatePress The WordPress.org directory describes it as a visual translation plugin, and its automatic-translation category page describes AI translation. These directory descriptions do not establish exact workflow or plan limits. Check the translation engine and allowance, language limits, URL and SEO features, and current free-versus-paid boundaries.

For product-specific details, consult WPML’s getting-started guide, its Translate Everything Automatically guide, the Weglot WordPress.org listing, the Polylang listing, and the TranslatePress listing.

Set up automatic translation safely

  1. Inventory what needs translating. List pages, posts, menus, forms, theme and plugin text, products, checkout screens, metadata, and other dynamic content. This helps expose content that a page-only translation workflow might miss.
  2. Choose one main multilingual solution. Install and configure a plugin or connect a hosted service. WPML’s wizard guides language, URL, engine, and translation-mode choices; Weglot’s documented workflow connects the plugin to an account and lets you select languages.
  3. Select target languages and language URLs. Decide how each language will be reached, such as through subdirectories or subdomains where supported. Weglot documents both structures, as well as hreflang tags and translated metadata. Choose the structure deliberately rather than assuming every plugin offers the same options.
  4. Enable the translation workflow and set review behavior. In WPML, the documented path is WPML > Translations > Dashboard; use Translate Everything only after checking the engine requirement, scope, and displayed cost. Weglot describes translations being presented for review before publication. These steps are product-specific, not universal settings for all multilingual plugins.
  5. Review translations before they go live. Check meaning, names, links, formatting, and terminology. WPML’s guide directs users to review translated content and send remaining work from its translations area. Machine translation should not be treated as publication-ready by default.
  6. Test the whole site on staging. Inspect language switching, menus, forms, dynamic strings, product details, checkout language, metadata, and mobile layouts. Test relevant theme and extension behavior; documentation for a plugin cannot establish compatibility with every WordPress site.
  7. Check how updates are handled. Verify whether edits trigger new translations, how manual changes are retained, and whether additional sends affect charges. Product billing terms can change, so use the provider’s current documentation and account display.

Understand multilingual SEO and hosted-service trade-offs

Language-specific URLs, hreflang tags, and translated metadata are technical SEO features Weglot documents; they are not proof of improved rankings. Search visibility depends on more than installing a translation tool, and the reviewed documentation establishes no ranking outcome.

Weglot’s hosted model also creates a portability consideration: the translations are stored on its servers, and the site will no longer be translated through Weglot if the service is discontinued. Its listing describes an export option, so review how that works for your site before relying on the service.

Compatibility, migration, and editorial review

  • The Polylang WordPress.org listing states a minimum of WordPress 6.5 and PHP 7.4. Verify the listing for current requirements before installation.
  • Polylang warns that leaving other multilingual plugins active can lead to unexpected results. Avoid running multiple plugins that each manage language versions unless their documentation explicitly supports that setup.
  • Back up the site and test plugin changes or migration on staging. Directory listings and vendor documentation are not a compatibility test of your particular theme or extensions.
  • For legal, medical, financial, and product-safety content, have a qualified human review translations before publication. Automatic output can alter meaning, and the documentation reviewed here establishes no accuracy guarantee.

WordPress.org’s localization handbook explains the distinction between preparing software for localization and adapting it for another language. For plugin-specific setup, rely on the current provider documentation and listings linked above; capabilities, language availability, costs, and compatibility can change.
