I currently run a service based business and have decided to broaden my audience based on my knowledge and authority. I am going to begin adding in content marketing for other pros within my industry and believe this will do two things. 1) Help build authority and credibility to my current/prospective clients 2) Lead to the ability to introduce affiliate links and/or educational programs to sale. My main question in working thought this is whether to use a subdomain, subdirectory, or a new domain all together? Thanks in advance.
