If you’re willing to take on some risk and have the heart of a true hustler, you can make extra money online doing commission-only sales for startups and other businesses. While you won’t be getting a regular salary, with the right sales strategies and skills as an inside sales rep, you can make decent money for each sale you bring in. And because you’ll most likely be working with startups, if you can negotiate a little equity you could profit big time if you're pitching a solid product and the startup succeeds.
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.
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.
A niche affiliate site often presents like an eCommerce store. To get started with an affiliate site, choose your niche then display products with pictures, descriptions, and prices, just as you would on an online store. However, when visitors click the ‘buy’ button, they will be taken directly to Amazon, to make the purchase. You then make an affiliate fee for sending the traffic to Amazon, but have none of the packaging hassle, or initial financial output creating or buying the products.
Now, it’s time to start creating and uploading content. Make sure you’re using a high-enough quality camera (most smartphones will work but I’d suggest at least having a tripod so your footage isn’t shaky), but don’t worry about being perfect at first. The beauty of YouTube is that you can continue to test out different content and styles as you find what works for you. Instead, stick to a regular schedule to build up your subscriber base.
Write pitches. If you have located a client for whom you want to write, send pitches, which are topic ideas for articles. Write pitches that not only show your expertise, but also demonstrate your enthusiasm for the topic.[21] First, read the publication to which you are sending pitches to familiarize yourself with what they publish. If applicable, identify a specific section and send our pitch to the appropriate editor. Also, include a brief summary of who you are.[22]

Writing copy for websites is another great freelancing option for those who have a way with words. Copywriting can involve writing the text for websites, press releases, promotional offline materials including leaflets and brochures, and any other professional text for businesses. Writing copy can be better paid than blog writing. However, clients can be more fussy, as they want the highest quality writing for the forefront of their website or advertising campaigns. Many freelance writers offer both copywriting and blog writing amongst their services. This can be a good way to juggle regular but lower paid clients (blogging) with the higher paid but ad-hoc project based copy work.

To do that, you have to harbor a few fundamental guiding principles in your mind. Today, if you're at all serious about generating a full-time income (and more) from your online activities, then you need to focus on passive income as opposed to active income. Sure, the active income will help you survive. That's the scarcity mentality at play. But it's the passive income ideas that will help you thrive.
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.

Amazon Mechanical Turk is a service that lets you make money online through doing paid microtasks. Each task is something simple that requires human interaction like rating search results, checking for the right spelling on search terms, categorizing the tone of an article, or even basic translating. You can do these tasks from anywhere you want and make money online from the world’s largest e-retailer.
Travel blogging is a hard industry to break into. However, the rewards can be worth it, and let’s face it, who doesn’t want to be paid for traveling around the world! There are numerous ways to monetize a travel blog, but affiliate marketing should predominantly be your focus. On your blog, promote hotels, tours, equipment hire services, flights, and anything else travel related. Then take a cut of the proceeds as your audience books their holidays based on your recommendations.
Great list! I’ve used Poshmark to sell clothes/accessories. You take up to 4 photos, add a description, and set a size, color, and brand. I’ve sold 3 items so far (two dresses and a pair of shoes) and it’s easy. The buyer can purchase at listing price or make you an offer, to which you can counter-offer. At all times, you can see what your profit will be from your listed price. Once the transaction is accepted, you are emailed a prepaid shipping label to print. You package your item up in a brown box and ship, and when the seller receives it your funds are released. You can cash out as a direct deposit to a bank account at any time or use the funds to shop. I’ve also purchased a pair of jeans on the site and they arrived as expected. For like-new and designer labels it’s a great way to clear your closet and make a little cash all at once.
One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
