In order to create a Multilingual Site, you have to use a translation plugin. Multilingual plugins offer WordPress users the ability to run a multilingual site with a single WP install.

TranslatePress is a translation plugin for WordPress that can be downloaded for free and used to translate your entire site directly from the front-end. The plugin is even compatible with WooCommerce so you can easily translate your entire storefront. Main features include:


  • User-friendly interface which displays the translation in real-time
  • Fully compatible with all themes and plugins
  • Support for both manual and automatic translation (via Google Translate)
  • Ability to translate dynamic strings added by WordPress, plugins, and themes.
  • An editorial control allows you to publish your language only when all your translations are done
  • And more.

It’s worth mentioning that the plugin does have a premium version that offers several add-ons which allow you to add unlimited languages, automatically detect a visitor’s language, display different navigation elements for different languages, and more.
