We have an opportunity to buy an extra domain that is quite specific to what we do and where we do it e.g. newyorkplumber.com.
This domain will just point to our current business's website url which is our business's name : fooplumber.biz
Does this new domain have any chance of showing up on search results if someone searches for "New York plumber"?
Is it worth while to buy additional pointing / forwarding domains if they are very specific to our business i.e. does it have potential to bring us any additional traffic?
