Marketing is a crucial function of the trainers today with the tremendous growth of social media marketing and online recruitment and selection. A trainer should look at the world like a marketplace where organisations from all parts of the world are potential clients and there is possibility of getting business. There is a need for trainers to act as unofficial marketers today where some amount of branding and marketing goes into their online personas, which informs others on their opinions, ideas, careers and their perception of the world.Generating few responses or having a few marketing skills in the professional toolkit initially is not a bad thing for a trainer. Learning how to think and operate like a marketer is increasingly important for a trainer, no matter what background he or she comes from. The trainer has to look into detail every aspect of online marketing. There should be a clear understanding of what aspects of marketing can be used and how to use them to market the trainer’s services and products and build his image.
