If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.

Rather than making money through subscriptions, YouTube channels are based on a traditional advertising system. Meaning the more viewers you get, the more you make. Once you’re approved for the YouTube Partner Program and can start including ads on your videos, with every 1,000 views, you will make approximately $2-$4. Which might not seem like a lot, but if you have 100 videos with 5,000 views a month each, that would be $1,000–$2,000 already. Just imagine if your videos start hitting millions of views!
Everyone says you're a fantastic writer, so isn't it about time you got paid? According to Durst, Good writing is in demand, especially for online content. Good freelance writing websites to find job listings include JournalismJobs.com, upwork.com, and MediaBistro.com. If you have experience as a copy editor, writer, or proofreader, go to editfast.com to find freelance opportunities in these areas.

Mechanical Turk is Amazon's take on micro-jobs. These are small miniscule-jobs that you can do for other people, which they call HITs, or Human Intelligence Tasks. These are super simple tasks that anyone can do. Some examples are listing off some URLs with certain kinds of images for one cent, or recording a few phrases with a microphone for 6 cents.
My next self-funded business hit $160,000 in revenue in its first year alone. After that first taste of self-made success, I’ve gone on to sign consulting contracts worth tens of thousands of dollars with startups like LinkedIn and Google, launch profitable online courses, and build a following of hundreds of thousands for this blog and my podcast series.
You could also opt to use existing websites for making money. These include both active income and passive income methods. For example, you could sell some used items or invest in creating some digital designs that then can be sold on merchandise. Again, devote a sizable portion of your time to passive income so that you can slowly build up earnings that will arrive on autopilot without any extra added effort. 
When you lack the luxury of time, making money on or offline can seem like an impossible task. How are you supposed to do that when you're working at a life-sucking nine-to-five job? While the stability of full-time employment might allow most to sleep well at night, it doesn't empower your creative juices to search for new income-producing strategies.

Today, if you're at all serious about succeeding in any endeavor, whether online or offline, you have to deliver enormous amounts of value. Yes, you have to do the most amount of work for the least initial return. This is especially true online. Why? Because it takes time to build authority and create an audience, two primary ingredients necessary to succeed in the wonderful world of commerce on the web.

The first follows the startup path we outlined above: You have a disruptive idea for an app or piece of software, you validate the idea with real customers, and then raise money to hire developers or a development studio to build, launch, and scale your software. If you’ve done everything right, your software will be accepted to the Apple and Google Stores and you’ll make money every time someone downloads it or pays for a premium feature.
Shepper says users are fully insured, and it takes precautions to ensure your safety, including reviewing every booking that it receives. It may be worth taking extra steps too, such as telling a friend or family member where you'll be and arranging to contact them after you finish the job. Remember to trust your instincts – if you feel uncomfortable with any job, simply leave. 
6. IZEA – IZEA works in addition to a blog or on its own. You get paid to blog, tweet, take photos and take videos. The pay is mostly based on your following, so if you want to make money with your tweets, you’ll need to grow you Twitter following.  Likewise, if you want to make money with blogs, you’ll need substantial blog traffic (more on blogging below).
Great article, I have tried a few over the years. I had a side business cleaning offices for years. It did great, but I hated never being able to take more than 3-4 days vacation, so I eventually gave up. I tried MTurk, but if you multiplied my earnings on an hourly basis, it was a little over $6/hr. My blog is much worse, probably less than $0.25/hr.
Bulk Selling: For all practical purposes, you can sell as many items as you like on Decluttr. If you reach the 500-item-per-order limit, just start a new order. This is a big advantage for folks staring down huge boxes of old DVDs, CDs, and textbooks. And it’s a distinct competitive edge on retail trade-in platforms, which may require users to enter their items one at a time.
Persistence and Commitment. You’ll need to have a good amount of persistence while pursuing freelance writing gigs. This business is subjective, and while one person may love your writing, another may not. Do your best to always produce good, solid copy and hold on to your commitment to do the best you can for your clients. Just by committing to do those two things, you’ll be miles ahead of your competition.
Storage. Depending on how big your business gets, you’ll need ample room to store the books. You can’t get lazy or disorganized about it, either. You have to keep the books in good condition, and you need to be able to find them when someone wants them. For instance, if you list a book in “like new” condition, and then the pages get smashed during storage, you’ll be in a bind if someone places an order before you realize what happened.
This isn’t to scare you off. I simply want you to know that this guide is going to focus solely on ways to make real, sustainable extra income online. Not just a few bucks. I want to share all the mistakes I've made that got me to where I am now so that you don’t have to go through them, and can build a successful online source of income for yourself.
2. InboxDollars – InboxDollars is similar to Swagbucks, since you’re going to be taking surveys, shopping, etc., so if you want to maximize your return, sign up with both websites. They also offer a search engine that pays you (like Swagbucks) and you get $5 just for signing up.  I won’t continue to list survey sites one after another down the list, but if you want to get paid to take surveys, also check out GlobalTestMarket, E-Poll Surveys and Survey Club.
