We'll create fresh WordPress site with Language switcher popup for WPML – stores selected language in a cookie – SEO friendly installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This plugin is an add-on for WPML (WordPress Multilingual Plugin). It detects the browser language of your user and shows a popup if his browser language is different from the default language of your website. There your user can change the language. Once the user selects a language, the information is stored in a cookie. When he visits the startpage again, he automatically gets redirected to the language he selected.
This plugin detects the browser language of your user. The pop-up only appears, if the user’s browser language is different from the default language of your website.
We will only redirect the user after he has chosen a language in the popup. So there is no automatic redirection without user interaction. As it is unclear, how this would affect your SEO.
Once the user selects a language, the information is stored in a cookie. This cookie is used to redirect the user to his preferred language.
When he visits the startpage again, he automatically gets redirected to the language he selected the last time.
