Need Suggestions On Creating Different Domains

Hello everyone,

I have an issue with a starting project.

I am writing articles in Dutch for my Dutch speaking citizens in Belgium, but since they also speak Dutch in the Netherlands I also want them to read the content but not from a .be domain but from a .nl domain.

Now, what is the best plan of action here?

Create 2 domains that point to the same domain, but then I notice if people from the Netherlands go to the .nl domain which is pointed to the .be domain they will still see the .be url in their browser.

I also do not want to duplicate content, altho. I need to write the article so that it will have both keywords in it, for Belgium and for the Netherlands.

I am a bit lost with this issue, any advice on how I should handle this?

Looking forward to the answers.

Best regards, Bjorn.
