If you have a background in a specific field, you may find there is a demand for writing industry papers in your area of expertise. For example, there are often adverts for doctors, lawyers, nutritionists, and business experts from particular niches, to write white papers on different subject areas. These are well paid jobs that you will need to stake your reputation on, but that can often be worked on from the comfort of your own home.
A website called AchieveMint gives you points for engaging in healthy activities, like exercise, tracking your eating habits, or even taking health related surveys. Points can be redeemed either for cash (10,000 points are worth $10) or for Amazon Gift Cards. The app actually connects with other health apps, like Fitbit and MyFitnessPal, to track your progress.
You've always heard of people getting rich off selling items on eBay and Amazon, but you don't need to have a business degree to figure it out. Anyone can start selling items they aren't using anymore on eBay in just a matter of minutes. Once you sell your first item, you can quickly find yourself addicted and start making a few hundred dollars per month selling your old and unwanted items. Amazon also offers similar services through their "sell on Amazon" services for anyone who might have their own products or bulk supply.
If you love to travel and find yourself randomly searching for airfare sales or browsing Lonely Planet, why not carve out a niche for yourself as a private travel agent? My friend, Mark Jackson did just that, making extra money online with his travel consulting side business. Start with word of mouth recommendations from friends who know they can count on you for the cheapest flights, and then move on and create a Facebook or LinkedIn group to invite people who want to stay on top of the latest deals. Eventually you could spin this into a full-time consultancy teaching people how to make their dream trip a reality.
If you are a budding photographer and would like to be paid for your craft then you should consider setting up your own photography website. This is a great way to not only promote your services as a photographer, but also to sell your images. You can charge visitors a fee to download your images. Or, if you’d rather, turn your site into a paid membership site, with free downloads of all images for paying subscribers.
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.
