These are sites that post short tasks that pay per piece. These tasks may involve anything and everything, including data entry, writing, tagging, surveys, and more. Most don't pay much per piece, but the key to earning substantial extra money with them is getting fast at the tasks you do accept. Below are a few sites to consider trying that pay for short tasks:
Considering that you have a finite amount of time, passive income should make up a large part of your work. And if you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Simply this. Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income?
Check if you need a model release. Photos of people can only be sold for commercial use if they've signed a 'model release' that gives you permission to use their image (children need a parent/guardian to sign). Without a release, these photos can still be sold for editorial use, as long as they were taken in a public place – eg, if you submitted a 'breaking news' shot with people in the background. If there's any doubt, always ask permission.
My real job does not pay enough. I do surveys online all the time and I am always looking for more ways to make money online. I would love to work from home full time but I honestly don’t see it happening. I am already a member of the survey sites mentioned here. But the truth is you are usually going to make closer to 30 cents to maybe 75 cents per survey. I hate seeing claims that you make $5 to as much as $75 per survey and for minutes of your time. Most surveys take 30 minutes or longer. Pay closer to 75 cents (that is 3 quarters) and there are lots of times you finish the survey and don’t even get paid. Anyone who has done the survey thing for very long knows this is true.
If you’re a skilled worker in a specific niche, like marketing, design, or software development, there are specialty marketplaces that cater just to you. These are amazing places to make money online as you know that the people visiting them are looking specifically for the skills you have. Check out places like 99Designs or Dribbble for designers, Cloudpeeps for marketing and SEO professionals, and TopTal, Crew, or Gigster for high-level software developers. Once you've built up your development skills, you can begin building a brand for yourself as a higher-value consultant and start charging brands for larger projects like implementing an entire WordPress security overhaul or migrating a website from http to https.
