I have a danish website raw58.dk and an english website raw58.com.
When a user enters the website i want them to be able to choose between the danish and english store.
Like this website: https://desenio.co.uk/ if you look in the top left corner.
I dont want the website translated.
What you are looking for is a geobased redirection tool. There is a great one called Geolizr that will redirect visitors to a country-specific store. You can view their app demo here to see how the redirection functions.
If there is anything else I can help you with, please let me know.
