Why Use Translera?

Translera helps make your WordPress site easier to read for international visitors while keeping your URLs structured for multilingual SEO. It is built around standard WordPress APIs, so it works with most themes and can be used through shortcode, block editor, Elementor, or PHP template code.

Configuration

General Settings

• Choose the default site language.
• Enable the languages you want to show in the switcher.
• Select Google Translate as the translation method.
• Choose subdirectory URLs or query parameter URLs.
• Enable or disable browser language detection.

URL Structures

Translera supports two multilingual URL formats:

• Subdirectory URLs: example.com/es/privacy-policy/
• Query parameter URLs: example.com/privacy-policy/?lang=es

Subdirectory URLs are recommended for clean, SEO-friendly multilingual site structure.

Google Translate

Translera can translate using Google Translate. You can leave the Google API key field empty to use the free translation endpoint, or add your own API key for Google Cloud Translation API requests.

Language Switcher

The language switcher can show flags, native language names, translated language names, or a compact flags-only layout. Available styles include:

• Dropdown
• Flags only
• List

Usage

Shortcode

Add the language switcher anywhere shortcodes are supported:

[translera_switcher]

Use shortcode options to customize the output:

[translera_switcher style="flags" show_flags="true" show_names="false"]

Gutenberg Block

1. Edit a page or post with the block editor.
2. Search for Translera Language Switcher.
3. Insert the block.
4. Choose the switcher style and display options in the block sidebar.

Elementor Widget

1. Edit a page with Elementor.
2. Search for Translera Language Switcher.

PHP Template Usage

<?php
echo wp_kses_post(
    Translera_Language_Switcher::render_block(
        array(
            'style'       => 'dropdown',
            'show_flags'  => true,
            'show_native' => true,
            'show_names'  => true,
        )
    )
);
?>

External services

This plugin uses Google translation services to translate page content and language-switcher labels. Translation requests are sent only when a visitor views a non-default language version of your site (or when an administrator runs a translation test from the settings screen).

Google Cloud Translation API

When you enter a Google Cloud API key in Translera > Settings, the plugin sends translation requests to the official Google Cloud Translation API (https://translation.googleapis.com/language/translate/v2).

What is sent: The text to translate, source language code, target language code, and your API key.

When it is sent: During server-side translation (when enabled via the translera_auto_translate filter), REST API translation tests from the admin, and any server-side caching of translations.

Service provider: Google LLC — Terms of Service, Privacy Policy.

Google Translate (free endpoint)

When no API key is configured, the plugin may use Google’s public translate endpoint (https://translate.googleapis.com/translate_a/single) for server-side and browser-side translation.

What is sent: The text to translate, source language code, target language code, and a client identifier (gtx). No API key is sent.

When it is sent: When a visitor loads a page in a non-default language (browser-side translation in frontend.js), during server-side translation when enabled, and during admin translation tests.

Service provider: Google LLC — Google Terms of Service, Privacy Policy.

Note: The free endpoint is not part of the official Google Cloud Translation API and may be subject to usage limits or changes by Google. For production sites, Google recommends using the Cloud Translation API with your own API key.
