Problem:
I've set up a couple of new subfolders for different languages and this works fine (e.g./fr).
However, we're a UK based site and as well as different subfolders for other languages, I'd like to set up another subfolder as a catch-all for other EU traffic that is English speaking (e.g./eu). This would be in addition to the main site (without any subfolders).
This is primarily for SEO reasons, for appearances (trust) for EU traffic, and also advertising. E.g. Google shopping is much easier to manage when you can provide different URLs for different regions.
Does WPML support the above?
Solution:
Let me please emphasize the following point. The WPML plugin is a multilingual plugin. It is about having your site in different languages. It is not about having your site in different locations. However, locales are linked to languages. This is another topic.
As my colleague suggested, creating a custom language may be the beginning of achieving what you need. However, I'm unsure if it will serve all of your purposes. First, let me tell you that using /eu/ as the language code for Europe will probably not work for you. The reason for this is that /eu/ is the language code for the Basque language. Therefore, you cannot add it as a custom language. This is because the Basque language is a preconfigured language in WPML. I also think that for SEO reasons, it would not be wise to use /eu/ for Europe or the European Union. I quickly checked my WPML test site and can see that creating a custom language with the /eur/ code works (any other language does not take this code). So maybe you can use /eur/. Saying that, please bear in mind that I or any of my colleagues are not SEO experts. I suggest you consult an SEO expert on what you are trying to achieve. This is also valid for your other questions.
