WordPress SEO

I’d like to structure my subdomain on my therapists directory called therapists.howdoidate.com so that a Google search for therapists New York would find a list of therapists on my directory site from New York.

So really the structure would be like this https://therapists.howdoidate.com/New York

Does anyone know how to achieve this structure – methinks it may be to do with permalinks but not sure.

Thank you
