WPML lets you redirect visitors to their preferred language, offering their native content as default.

To enable browser language redirect, go to WPML->Languages->Browser language redirect.

The default is not to redirect visitors. You can change it to redirect only if translations exist, or redirect always. If redirecting always, visitors will go to translated content when they exist or to the homepage in the other language, if translations are missing.

Potential Interaction with Google Indexing

As of 2015, Google follows all redirects, including those implemented in Javascript. This may cause Google to think that your content permanently redirects to content in other language. Read more about how browser language redirect affects Google Indexing.

No Redirection When Refreshing the Browser

WPML will do this language redirect only once and then not redirect anymore. We do this to allow visitors to still switch languages. If we always push back to the browser’s language, visitors will not be able to manually switch languages after WPML redirects them to the language set by their browser.

This single-time redirect operation resets every 24 hours (which you can change too).

How Browser Language Redirect Works

WPML uses Javascript code for the browser language redirect. This way, the redirection is fastest, as it happens in the visitor’s browser. It’s also resilient to caching plugins.

However, the language redirect mechanism may fail if your site is running other plugins that also redirect based on Javascript. Some maintenance plugins may do that.

Tip: Always Include a Language Switcher on the Page

The browser language detection is intended to send visitors to the content which will match their language preference, on the first visit. You should always allow visitors to choose their preferred language using a language switcher. If you rely exclusively on the automatic language redirection, some visitors will receive content in languages that they cannot understand and will not be able to switch to their preferred language.

Debugging Browser Language Redirection

If you’ve enabled browser language redirection and it isn’t working when you test it, check the following:

  • Is your browser’s language set? Go to the language setting in your browser and check it.
  • Are you using a new session? Remember that WPML will only do this once. If you clear all cookies or start an incognito browser (which always has a fresh history), you should have a clean session, simulating a new visitor.
  • Are there any Javascript errors on the page? You can view Javascript errors using Tools->Javascript Console on Chrome and Firefox.
  • Are you using any other plugins that might be redirecting visitors too? Review your active plugins and see which ones might be involved.
  • Is the language you expect to be redirected to hidden? Make sure you enable “Display hidden languages” from your user profile
