What is the browser language condition?

The browser language condition lets you add or replace content on your website according to the users’ defined languages for their browser.

How can your site benefit from the browser language condition?


  • Improve engagement by displaying a short message in your visitor’s language.
  • Translate your website’s calls to action – a proven way to improve conversion rates.
  • Display testimonials or product recommendations in the visitor’s language.
  • Redirect users to a page in their own language (or add a suggestion to visit a page in their language).

About browser language

Most desktop browsers have settings that allow you to edit your language preference settings. These tell the server what language you prefer for pages and resources that it sends you (separate from the language of the browser user interface).

For browsers on mobile devices, the language preferences are likely to be determined by the operating system settings, or in some cases by the language of the system when you installed the browser.

Browsers that allow you to change your language preferences will generally allow you to specify a list of languages so that if your first choice is not available, you can set which alternative languages to try, and in what order.

How to configure the browser language in common browsers:

Your browser language/s:
Primary language: EnglishOther language/s: English (en)

Display dynamic content only if the language is set as primary (optional)

As written above, some browsers allow users to specify a list of languages so that if their first choice is not available they can set alternative languages to try, and determine their order. If-So allows you to choose whether to display the dynamic version for a primary language only, or also for secondary browser languages. This option is extremely useful when you want to grab visitors’ attention with a message in their mother tongue.

The option is useful, since in many cases the browser language condition is used to grab visitors’ attention with a message in their mother tongue language.

Which content can be customized using the browser language condition?

Same as with all of If-So’s dynamic triggers, any of the website’s content can be customized. That includes titles, texts, images, calls to action, buttons and more.


How to set up browser language-based dynamic content using If-So

  1. On your WordPress dashboard, go to “If-So → Add New Trigger.
  2. Click on “Select a condition” and select “User Behavior → Browser Language “.
  3. Select a language
  4. In the content field, set the content to be displayed if the language appears on the visitor’s configured language list
  5. In the default content field, set content to be displayed if the language does not appear on the visitor’s configured language list.
  6. Press “Publish” and paste the shortcode generated by If-So in your website.


  • Will this work with server and WordPress caching solutions?


    Whether you are using a caching plugin or server caching, you can navigate to the plugin settings and enable the "Page Caching Compatibility" option. With the option enabled, dynamic triggers will be rendered in a separate request that will take place after the loading of the cached version.

  • Can I redirect users to a different page based on conditions?
    Yes. You can redirect users based on each one of the conditions by pasting a simple JavaScript code in the dynamic version content field. Click here for a step by step guide.
