How to Detect Browser Language Automatically

detect browser language automatically

Allowing users to view content in their preferred language is an essential feature of websites that aim to reach a global audience. As a site owner, you can easily do this by setting up your website to detect browser language automatically.

Website translation is no doubt the first step to creating a multilingual website. But after creating multiple translated versions of your site, redirecting users to their preferred version automatically takes the browsing experience an entire step further.

Granted, having a language switcher button or page remains important for virtually any multilingual website. But automatic browser language detection helps your customers navigate your site even faster. This can in turn boost the user experience (UX), engagement, sales, and conversion.

In this article, we’ll take a look at how automatic browser language detection works and why it’s important. We’ll then show you how to use our go-to multilingual plugin, TranslatePress to activate automatic browser language detection on your WordPress website.

How User Language Detection Works

At some point, you may have visited a foreign brand’s website, only to discover that you’re viewing its content in your native language. That’s possible because the website can detect your preferred language automatically.

Wondering if this has anything to do with some privacy law violations? Not to worry, automatic user language detection works based on simple logic that has nothing to do with spying on your personal information.

There are three major ways websites detect users’ preferred language. It could either be based on browser preference, IP address, or internationalization.

Browser Preference Detection

This is the most popular method websites use to detect browser language automatically. Once you install a browser on your device, you would usually select your preferred language.

When you then visit a website within this browser, the website can easily detect the preferred language stored in the browser’s settings files. The website then uses code (in most cases, Javascript) to redirect the user to the corresponding pre-translated version of the site. As a website owner, you can choose to do this automatically or ask the user if they want to see your site in the detected language.

When setting up automatic browser language detection, it’s important to let visitors choose their preferred language once they get on your website. An automatic language switcher helps with that.

But people speak thousands of languages around the world. And you may wonder which languages to translate your website into. One possible approach to resolving this is to translate websites into the most widely spoken languages in the world.

However, as a best practice, it’s more rewarding to consider the languages common to your target audience. You can easily do this by analyzing the specific countries where most of your site visitors come from presently and aim to reach them better.

Google Analytics comes in really handy here. If you want to learn more about choosing the right languages for your multilingual website, you can check out our complete guide on how to translate WordPress.

IP Address Lookup

Another method websites use to detect browser language is by checking the site visitor’s IP address. Once the site completes the IP address lookup, this will in turn reflect the user’s location. It will then redirect the user based on their location.

But this method comes with some challenges. A user’s language preference may sometimes differ from their location information. But a typical IP address lookup cannot tell them apart.

For example, if the website has identified your location as the US and you travel to a non-English speaking country, the IP address updates your location and gives you the version of the site that corresponds with your new location. This means that if you don’t understand the prevalent language in your new location, you may have a difficult time engaging with the site’s content.

Similarly, there are countries like Canada or Cameroon with more than one lingua franca. Going with the more popular language option might not always be spot on. Similarly, if a site visitor is also using a Virtual Private Network (VPN) connection, then offering website translations based on the location may deliver undesired results. Because of these hitches, websites hardly detect browser language with this method.

Internationalization

Aside from automatically detecting browser language for entirely different languages, websites must also pay attention to language variations. A popular example is the English language which has US and UK variants. These variations have different spellings, styles, and formats.

To ensure effective localization, your website’s automatic language detection should be such that users can distinctly detect both variants. You can use either of the first 2 methods to get efficient results as regards internationalization.

Why Detect Browser Language Automatically?

When people visit your website for the first time, they’re hoping to access its content in a language they understand. That is why it’s important to set up automatic user language detection on your website.

Once you set up your site to detect browser language automatically once, it’ll always remember the language previously used by visitors through a cookie. So when users revisit your website, they can automatically access it in their preferred language.

In most cases, a global site will often get new users whose browser settings or IP address reflect a different language other than your website’s preset language. When you activate the Automatic User Language Detection add-on, such visitors get to see a popup with an option to switch to the detected language.

You can also set things up in a way that redirects visitors to their language without pre-informing them. The challenge with this is that it may not help your website’s indexing because of the constant changes in Google’s algorithm.

In either case, you’ll get to enjoy the following benefits:

  • Your site’s browsing experience will be improved significantly;
  • You’ll get more engagement on your landing pages and sitewide;
  • Users will spend more time on your site, which also boosts your Search Engine Optimization (SEO) rankings;
  • Your business will land more sales and conversion.

In essence, detecting browser language automatically makes your multilingual site more user-friendly and ensures that your internationalization efforts yield maximum return on investment (ROI).

How TranslatePress Detects Browser Language

TranslatePress uses the Automatic User Language Detection add-on to execute user language detection. This does not involve any technicalities or registration for IP language address services because Maxmind’s GeoLite2 databases aid the language recognition locally.

Your site can detect users’ language, either through the browser language setting or IP address. As we’ve explained previously, the browser language setting is the preferred option. But overall, you need to consider your target audience when determining the best choice for your website.

You can easily change the preset mode of considering the browser language before the IP address by going to Settings TranslatePress Advanced within your WordPress dashboard. Here, you have the option to determine visitors’ languages with the browser language, IP address, or both. If you decide to use both, any of them can come first.

After that, you can decide whether you want to redirect visitors to the detected language as soon as they open your website. Otherwise, you can notify them about the language detection with a popup or hello bar. If you choose to notify your users before redirecting, you can also customize the message you want them to see.

There are generally two kinds of redirects you can use after detecting browser language automatically: hard and soft. Hard redirects occur on the server’s end and are simply incompatible with caching systems.

This relates to both plugin-based and host-based caching systems. This is because the site visitor only gets to see a cached version of the page. In other words, they never get to see the translated version of the page that the server code redirects them to.

In addition to this challenge of caching, hard redirects also require visitors to accept cookies and grant JavaScript access to run.

Fortunately, the Automatic User Language Detection add-on solves these hard direct problems efficiently. It uses soft redirects only, which occur on the client side.

Bonus Tip: Always Add a Language Switcher to Your Site

Relying on automatic language redirection is not enough to allow visitors to access content in their preferred languages. You’ll still need to add a WordPress language switcher, irrespective of the type of multilingual website you own.

A language switcher allows users to view content on your website even in cases when your site detects the wrong browser language. This doesn’t pertain to technical errors only. A user may choose to view your site in a language other than their local language or their browser’s preset language.
