Freelance writing is a writing career in which you work as an independent contractor, developing written communication for various clients. The client usually lays out specific objectives for a project. Your job is to meet those objectives by generating copy matching the tone and style that they want. Freelance writing is usually not about your creative expression as much as it is about writing in the voice your client desires. Your writing must be technically accurate as well since poor grammar and structure can detract from what your client is trying to say.
The online application process for these jobs—or perhaps “gigs” is the better word, since they're all for independent contractors—is pretty simple and straightforward with very little required of candidates. Some of these opportunities—like the micro-jobs—you could very well apply and start the same day. And these jobs require very little commitment and can typically be done on your own schedule.
