Introduction to Multilingual Content in Drupal

Drupal is a powerful content management system (CMS) that offers extensive capabilities for managing multilingual content. As businesses and organisations expand globally, the need to provide content in multiple languages becomes increasingly important. This article delves into the best practices for optimising Drupal for multilingual content, ensuring that your website can effectively reach and engage a diverse audience.

Understanding Drupal’s Multilingual Capabilities

Drupal’s core provides robust multilingual features that can be extended with various contributed modules. Understanding these capabilities is crucial for effectively managing multilingual content.

Core Multilingual Modules

Drupal 8 and later versions come with four core multilingual modules:

• Language: Adds language handling capabilities to your site.
• Content Translation: Allows translation of content entities such as nodes, taxonomy terms, and custom blocks.
• Interface Translation: Enables translation of the user interface.
• Configuration Translation: Facilitates translation of configuration entities like views, blocks, and menus.

Contributed Modules

In addition to core modules, several contributed modules can enhance Drupal’s multilingual capabilities:

• Entity Translation: Provides an alternative to Content Translation for translating entity fields.
• Localization Update: Automatically updates translations from the Drupal community.
• Language Switcher: Adds a language switcher block to your site.
• Pathauto: Generates URL aliases based on configurable patterns, which can be language-specific.

Setting Up a Multilingual Drupal Site

Setting up a multilingual Drupal site involves several steps, from installing the necessary modules to configuring language settings and translating content.

Installing and Enabling Multilingual Modules

To begin, install and enable the core multilingual modules:

1. Navigate to Extend in the admin menu.
2. Search for the multilingual modules (Language, Content Translation, Interface Translation, Configuration Translation).
3. Select the modules and click Install.

Configuring Language Settings

Once the modules are enabled, configure your site’s language settings:

1. Go to Configuration > Regional and language > Languages.
2. Add the languages you want to support on your site.
3. Set the default language and configure language negotiation settings.

Translating Content

With the language settings configured, you can start translating content:

1. Create or edit a content entity (e.g., a node).
2. Click the Translate tab.
3. Select the language you want to translate the content into.
4. Enter the translated content and save.

Best Practices for Optimising Multilingual Content

Optimising multilingual content in Drupal involves several best practices to ensure a seamless user experience and efficient content management.

Consistent URL Structure

Maintaining a consistent URL structure is essential for SEO and user experience. Use the Pathauto module to create language-specific URL patterns:

• Go to Configuration > Search and metadata > URL aliases.
• Configure patterns for each content type, incorporating language tokens (e.g., [node:content-type]/[node:title]).

Language Switcher

A language switcher allows users to easily switch between languages. Add a language switcher block to your site:

1. Go to Structure > Block layout.
2. Add the Language switcher block to a region of your choice.
3. Configure the block settings as needed.

Translation Workflow

Establishing a clear translation workflow ensures that content is translated accurately and efficiently. Consider the following steps:

• Assign translation roles and permissions to team members.
• Use the Content Moderation module to manage translation states (e.g., draft, in review, published).
• Implement a review process to ensure translation quality.

Automated Translation Updates

Keeping translations up-to-date can be challenging. The Localization Update module can help by automatically updating translations from the Drupal community:

1. Install and enable the Localization Update module.
2. Configure the module to check for updates regularly.

Performance Optimisation for Multilingual Sites

Performance is a critical factor for any website, and multilingual sites are no exception. Implementing performance optimisation techniques can improve load times and user experience.

Caching

Caching is essential for improving performance. Drupal offers several caching mechanisms:

• Page Cache: Caches entire pages for anonymous users.
• Dynamic Page Cache: Caches dynamic content for authenticated users.
• Render Cache: Caches rendered output of individual components.

Content Delivery Network (CDN)

A CDN can significantly improve load times by serving content from servers closer to the user. Popular CDN services include Cloudflare, Akamai, and Amazon CloudFront.

Optimising Images

Images can impact load times, especially on multilingual sites with diverse content. Optimise images by:

• Using responsive images to serve different sizes based on the user’s device.
• Compressing images without compromising quality.
• Using modern image formats like WebP.

SEO Considerations for Multilingual Content

Optimising multilingual content for search engines is crucial for reaching a global audience. Implementing SEO best practices can improve your site’s visibility and ranking.
