If you are in a position or career that networking and marketing a product are of the utmost importance there are many reasons why you should create a professional online portfolio, perhaps too many reasons to talk about. First things first, someone who is marketing a product absolutely needs to create a website that promotes that product and gives specific details about that product and what potential it has. As a personal trainer, my product is myself and my ability to help others achieve their fitness goals and desired body composition, therefore, it is imperative that I create a website for myself that displays what I have achieved as a fitness professional and what I can do for others. One way that I do this is through the use of this blog, it allows me to reach out to others and give out free helpful information to people, it is also useful for displaying my knowledge and reaching out to people for networking purposes. I also have several social media accounts that I use as networking and marketing tools; these include Facebook, YouTube, Instagram, Twitter, and a few others. I honestly cannot think of any negative reason for a person to have a online professional portfolio. The only thing would be people posting negative things that reflect poorly on themselves. Another very important online tool that any professional should use is LinkedIn. This tool allows people to network and is a useful tool to meet people in professional industries that are related to one's interests. People can use LinkedIn to show off their resume, skills, pictures, and a few other important things, not to mention useful in getting hired for a desired job.
