Everyone, across industries, needs a website.
A website gives you control over your image.
Whether you are applying for a new job or starting a side project, most people will search for your name online. Having the control over what information you would like to share (including your achievements) is such a powerful thing.
The more extensive your site is, the better impression you’ll make -- and reaching more people means more connections, opportunities, and so forth.
A website allows you to stand out from the competition.
Depending on the industry, focus on highlighting your unique strengths and identifying what things make you stand out. If you are applying for a new role, include your past (and relevant) experience, things you have done (such as volunteer work, projects etc.).”
In this way, a website can function similarly to a resume. However, a personal website has the freedom to be much more extensive and engaging, since it allows for the inclusion of photos, work samples, and even testimonials.
