If you intend to become better employed, self-employed, or even become an employer yourself then you should start off by having a personal website so you can learn how to converse with your market (marketing) and become market-driven. Quite a few personal websites have become corporate websites. It’s always a good idea to work on your personal site so that you will be more knowledgeable if it becomes necessary for you to build your professional, or even corporate, site. Your personal website may show the world your expertise, your communication style (artistic, logical, humorous, practical, bold. action-oriented) and your achievements at the touch of a button. Similarly, your corporate site may show your services, your corporate culture, and list your successful projects. A website is the most cost-effective, far-reaching, permanent promotional tool you may ever have both personally and professionally. If you do plan to have a website at some point then it would be a good idea to reserve the domain name(s) you intend to use, before someone does.
