When managing a multilingual website, you might want to automatically detect the visitor's browser language and redirect them to the corresponding content. WPML, a multilingual plugin for WordPress, offers an option to automatically recognize browser language for redirection. While such auto-redirection improves user experience, it might lead Google to perceive that all visitors can only access the default language page, potentially causing SEO (Search Engine Optimization) issues. Therefore, if you're considering using this feature, weigh the risks related to SEO carefully before deciding.
WordPress WPML: Automatic Browser Language Detection Redirect Options
If you aim to transform your WordPress site into a multilingual platform, the WPML plugin allows you to use its auto-translation feature for easy translation into various languages. Alternatively, you could leverage ChatGPT for translations, copying and pasting the results to translate pages or posts.
Some websites detect the browser language to redirect users to the corresponding language version. If you wish to enable such a feature on your multilingual site, you can activate the Browser Language Redirect option in WPML.
Activating/Deactivating WPML's Browser Language Redirect Option
If you want to automatically redirect users based on their browser language, you can configure the browser language redirect option.
1 Click on WPML » Languages » Browser language redirect tab in the WordPress admin dashboard.
2 Proceed to the Browser language redirect section.
You can choose from the following three options:
- Disable browser language redirect (Default)
- Redirect visitors based on browser language only if translations exist
- Always redirect visitors based on browser language (redirect to the home page if translations are missing)
If you want to redirect visitors based on their language, select option 2 or 3.
3 For example, choosing "Redirect visitors based on browser language only if translations exist" will prompt a warning pop-up.
The warning states that implementing browser redirection could affect Google indexing (crawling) and search results.
Keep in mind that activating the browser language redirect option may lead to SEO challenges. If, despite the warning, you still want to utilize this feature, click the Got it, activate anyway button.
4 If you select option 2 or 3, a notification stating "Browser language redirect may affect your site's indexing" will appear. Choosing these options means the visitor's language preference will be remembered for a set duration (default is 24 hours, adjustable in multiples of 24), allowing the visitor to avoid redirection upon returning.
Considerations When Using Browser Language Redirect
Google Indexing Issues
Since 2015, Google has followed redirects implemented through JavaScript. This can lead to Google interpreting that certain content is permanently redirected to another language. For details on how browser language redirection affects Google indexing, refer to Google's documentation.
No Redirection on Browser Refresh
WPML executes redirection based on browser language only once. After that, for the predetermined duration, automatic redirection will not occur. This design allows users to manually select their desired language. If redirection occurred every time based on browser language, it would prevent users from making their own language choices.
The language preference of visitors is stored for a specific time (default: 24 hours) and resets afterward, allowing one last redirection if they return again.
Method of Browser Language Redirection
WPML handles language redirection through JavaScript executed in the browser. This method offers speed advantages and is unaffected by cache plugins, ensuring reliability.
However, caution is needed as conflicts may arise if you're using other JavaScript-based redirect plugins (like some maintenance plugins), leading to potential redirection issues.
Impact on Page Load Time
To detect browser language, WPML needs to fully load the site before reloading the page according to the language. This process occurs only the first time a visitor accesses the site, but since it loads the page twice, the overall loading time may be longer than usual.
Conclusion
With WPML, you can create a multilingual site that automatically redirects visitors to the appropriate language page based on their browser language.
However, keep in mind that this approach may impact how Google crawls and indexes your site, so proceed cautiously. As an alternative, consider redirecting to the homepage based on browser language when accessing it.
