At the first visit, a customer will see the content in the language that you will link to their browser. Because the feature allows redirecting the target pages to those on their browser languages on your store. What if the customer's language is not included in your language list? No need to worry about it, the feature will link customers to pages of the fallback language you set. If a customer chose a language in the language selector, in the next visit he will be redirected to the pages of the language he chose. Customer selection takes precedence over his browser language.
