Microjobs can involve a huge range of different tasks. Some are quite fun, others are bitterly monotonous. One day you might be categorizing YouTube videos, the next writing short product descriptions, and the next recording your voice over and over again to help train Siri-like recognition systems. Many people look for online data entry jobs, and some microjobs are along those lines.
I worked as a freelance academic writer for about 5 years and Uvocorp was one of the 7-8 sites I worked with. I totally agree with Norbert. Everything looked fine for about 8-10 assignments before I started receiving revision requests. I had them review their comments and remove fines for the first two revision requests. However, I just gave up when I got the next seemingly senseless plagiarism remark. I was not sure if it was unintentional from their part, but I felt annoyed and disappointed by then.
Nice sharing and totally informative for those who want to earn online. I have heard a lot about watching ads and complete survey, and I want to know that do they really pay? I read that lots of fraud sites are there which offer such service and takes money to signup and then they are not paying to users. Can you please share trustable sites if you have some?
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.
