It’s fairly easy to build your own website if you take advantage of the many free learning opportunities online. However, much of the population isn’t equipped to build their own site, or doesn’t have the time, which is why so many people make a living building websites and blogs for others. According to the BLS, around 16% of web developers were self-employed in 2016, with the vast majority able to work at home, or anywhere with a laptop and speedy Internet connection.
These little jobs are done by people who log on to a company’s site and choose tasks, which could be as simple as clicking a link. Amazon's Mechanical Turk is one of the most well-known sites of this type. Also, there are crowdsourcing projects, which are similar to data entry, where companies engage an army of virtual workers to each do one small part of a larger project.
