Robert said he did an average of 4-6 of these gigs per year for a while depending on his schedule and the work involved. The best part is, he charged a flat rate that usually worked out to around $100 per hour. And remember, this was pay he was earning to advise people on the best ways to use social media tools like Facebook and Pinterest to grow their brands.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent.

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.

Many work-at-home companies hire you as an independent contractor as opposed to an employee. That means you are responsible for submitting your own tax payments. Taxes won't be taken out of your check like you are probably used to. It's so important that you keep good records of your income – and expenses. I highly recommend Quickbooks Self-Employed.
Matched Betting (not available in the USA) enables you to gamble (nearly) risk-free. I say nearly as there is always room for error! It involves placing bets on all outcomes of an event, using free online bets given out by the Bookies.

Writing an eBook and selling it on your blog can be a great money maker. Your eBook should be directly relevant to your blog’s content so you can sell your book to your existing audience. Creating a recipe eBook for a food blog or an eBook full of training plans to complement your fitness site are just a couple of examples that have the potential to sell.
Fancy yourself a good designer? Try your hand at creating a logo or other design that a company loves! 99 Designs is the most popular marketplace. Beware, however; you won’t get paid unless your logo wins against many others, which makes many designers unhappy.

Who doesn’t want to earn more money? Whether it’s through part-time jobs or freelance work, adding more dollars to your cash flow every month is always nice. But unfortunately, not everyone has the time to pick up another job or do additional work on the side. If that’s the case for you, don’t give up. Instead, turn to the one thing you probably spend a majority of your time on: the internet.
Sell stuff online. If you have high-quality items to sell, there are a slew of online marketplaces you can use. Just make sure you understand the fees associated with your sale before you take the plunge. Where neighborhood Facebook pages and Craigslist ads are free, many online marketplaces or consignment shops charge for ads or require you to fork over a percentage when you make a sale.
Some businesses may be interested in adding other types of paid content to your website. This could include videos, podcasts, or any other material that would work with your site and help a business market itself. Always make sure that paid content isn’t too promotional. It needs to add value to your audience first and foremost, and not just present as an advert.
