How do you serve a page with content in multiple languages?
Câu trả lời
To serve a page with content in multiple languages, you can follow several best practices and techniques that ensure your website is accessible and user-friendly for a global audience. Here’s a detailed guide on how to implement multilingual support on your web pages:
1. Use the HTML lang Attribute
The lang attribute in HTML is used to declare the language of a web page or a portion of a web page. This is critical for accessibility tools like screen readers, and for search engines to serve the content in the correct language to users.
Set the lang attribute on the <html> tag to specify the default language of the text in the page. For example:
<html lang="en">
For content in a different language from the main document, use the lang attribute on specific elements. For example:
<p lang="es">Este párrafo está en español.</p>
2. Organize Content and Directories
For websites with substantial multilingual content, organize the content into different directories for each language. This approach helps manage content efficiently and improves SEO for different languages.
Use a directory structure based on language codes, like /en/, /es/, /fr/, etc. Each directory contains the language-specific version of your website[11].
3. Implement Language Selection
Provide users with the option to select their preferred language. This can be done using a language switcher—a common UI element that allows users to switch between different available languages.
Place a language switcher prominently on your site, often in the header or footer, so it's easily accessible on every page[15].
4. Use Automatic Redirection (with Caution)
Automatically redirect users to a language based on their browser settings or IP address. However, always allow users to switch back to their preferred language as automatic detection might not always align with user preferences.
5. SEO Considerations
Use hreflang tags to tell search engines about the language and regional targeting of your pages. This helps in serving the correct language page in search results.
Example of hreflang usage for English and Spanish versions of a page:
