As we now offer our service in English, Norwegian and Danish, we used the weekend to translate the website into Danish and Norwegian.
We used the plugin called Polylang (https://polylang.pro/) to easily set up the new structure in Wordpress and Ahrefs (https://ahrefs.com/) for doing keyword analysis for the different languages.
Polylang is faily easy to get into and they have a good support site (https://polylang.pro/doc/) that helped with the most common questions we had.
