For example, my SEO writing company regularly produces ebooklets of 5-15 pages, charging anywhere from $500 to $1,500 depending on the subject matter. And, these only take a week or two to produce.II. Writing for Mobile Devices: Consumers are using their mobile devices more than ever these days to surf the web, check email, upload photographs, interact on social media, etc.The article, Making Mobile Better: Mobile Computing Devices May Overtake Personal Computer for Internet Use in 2013, on the Science Daily website underscores how fast this phenomenon is growing stating:Mobile computing devices will probably overtake the personal computer as the most common means for accessing the Internet worldwide sometime in 2013. Text has to be written in a certain way for mobile devices. For example, one of my company’s newsletter subscribers asked back in 2011 if I could start including shortened links in the text because she read most of the newsletters on her mobile phone and couldn’t click on hyperlinks (the text had to start with a http://).The point is, learning how to write for mobile devices is a specific skill – and if you know how to do it, you can charge handsomely for it.III. SEO Content Writing: Writing for SEO has to do with writing content in such a way that helps companies get found online. It improves brand visibility, as well as generates sales and leads. And, this is why companies pay freelancer writers (in a lot of cases) pretty well to produce it.How Much Can You Charge as an SEO WriterFor example, for writing a 50-300 word blog post, a freelancer can charge on average of $25-$45 per post. For longer SEO articles, (eg, 350-500 words), a freelancer can realistically charge $35-$75 per article.Remember, these are just averages. Some freelancers charge more, others less. But as you can see, even writing just a few articles and/or blog posts per day can earn you a great part-time or full-time income – working right from the comfort of your home.Digital Freelance Writing Jobs: ConclusionAs these three opportunities demonstrate, there are a wealth of freelance writing opportunities brought on by the digital age, which makes finding freelance writing jobs — online in particular – limited only by your imagination.
