most probably you mean local marketing, which means advertising in a confined area like a city or a country instead of worldwide, that's what I understand from it.
Rural marketing is one part of general marketing. It has separate characteristics, which needs to be attended to in different manner keeping in mind their problems , priorities, likings etc.
Thank you for that response. I must admit - after spending the past year doing online marketing this is the first time I had heard of "rural marketing". Great info
