Social media resellers come in several different shapes and sizes. However, for the most part they specialize in helping people and companies broaden their customer bases through useful marketing solutions. As such, they welcome social media as a nice complement to what they do every day.
Social media resellers tend to generally be marketing experts of some sort. These marketing experts have know how in a particular segment of marketing. However, their expertise does not lie too strongly in social media, so they resell it to gain exposure and experience and better assist clients.
Not all social media resellers are in marketing, though. Many get their paychecks by working in web site creation and design. Others specialize their skill sets in computer technologies. All resellers do different things, but their common ground is a drive to aid clients with their own online exposure so those clients can better succeed.
