Welcome to the Q&A Forum

I'm working on putting together an Inbound Marketing program for our company.  This is all very new to me, but I am having a difficult time determining keywords that are best for us.  Most words I choose have low search volume and there aren't many alternative words for what we do.  I'm not sure if it's just a really small market, if business that's conducted in our space is more by word of mouth and less online research is being done, or if I am just doing this completely wrong. We are a Mortgage Servicing Company looking for B2B clients. Keywords I am using are:
Subservicing, Mortgage Servicing, Mortgage Co-Issue, Service Mortgage, Mortgage Solutions Am I wasting my time with Google AdWords and keywords?
