I was chatting with my mom over the weekend about how the different online advertising campaigns she was trying were doing for her business. She is the business manager and co-owner of a chiropractic wellness center in Georgia. What I heard made me cringe. She told me that the money she was spending on internet advertising wasn’t providing a return on investment. She also told me that after several years of trying various online advertising campaigns most of her business still comes from word of mouth advertising.
