I'm designing a job site in D7. Ideally for better SEO each state or city should be in separate subdomain(this what I've learnt).
For city Paris it'd look like: paris.myjobsite.com
I'd post jobs using taxonomy categorization e.g. city,state, zip code, field, salary, qualifications.
Now I can host a new Drupal site on each sub domain so for 100 city/states it'd have 100 separate Drupal databases using multi site setup.
The other solution is to have a rewrite rule translating subdomain to site's internal url.
I'm unable to think beyond this.
I'd appreciate help as to how this design issue can be met in Drupal.
