Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
Work remotely for a call center. Because many call center jobs are location independent, finding work in this field is an easy way to earn some money from home. Dozens of sites list job openings for call-center representatives, including Freelancer.com and SimplyHired.com. Meanwhile, you should check local job listings for openings and opportunities as well.
Start a small business. Being passionate usually translates to a superior product and better service, which is especially sought after in the age of the anonymous, 1-minute online review. Worried that there isn’t a market for your interests? The fact is that though you may not personally know many people who want what you have to offer, thanks to the internet, there’s a huge market for niche-products (pigeon diapers, chainmail wedding dresses, you name it)… and you might just end up being a trend-setter. To create an online store, you can either make your own website or, if don’t want to self-host, you can sell on eBay or a similar site.
Tutor students. If you have an academic specialty and can squeeze in a couple of hours during the week while Junior is taking a nap or Janie is at gymnastics, share your knowledge with struggling students. Find students looking to improve their grades on your own through your kids' schools – check a site such as Craigslist.org to gauge hourly rates in your area – or sign on with an online tutoring company, such as Tutor.com. You must be available to tutor at least five hours a week and have a college degree to tutor certain subjects for Tutor.com. Tutoring is done virtually from home via a computer, not in person. Tutor.com tutors are paid an hourly rate based on the subject.
What does that mean for you? It means Nielsen will pay you $50 a year to keep their app on your favorite internet browsing device. The app itself collects statistics on your internet usage anonymously, so you never have to worry about any data being linked to you. And the best part is, the app takes up barely any space and doesn’t slow down your phone or tablet at all!
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
Learn then selling guidelines. Each marketplace has guidelines that define what you can and cannot sell. State and federal laws also impact what items are prohibited. In general, you cannot sell alcohol, weapons, service contracts, animals or event tickets. Also, while not always prohibited, you may find restrictions on how you can sell items in some categories, such as art, gift cards and coupons. eBay, Craigslist and Amazon publish these guidelines on their websites.
Consider selling in lots. A lot is a collection of similar items that is sold in a group. For example, if you have a collection of books, magazines or similar pieces of jewelry, consider selling them all at once in a lot. You many not make as much money as you would have if you sold each item separately. However, the items will likely sell more quickly in a lot than they would individually.
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. 
Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
Write and publish an eBook. You don’t need a traditional publisher and financial backing to publish your own book anymore. In fact, Amazon.com makes it possible for you to publish your own eBook and sell it independently – with no financial investment on your part. And with Kindle eBook publishing, your book will appear on Kindle stores worldwide within 24-48 hours.

Infographics are currently an extremely popular type of media. An infographic showing information or data in an interesting and fun way can help engage an audience and generate numerous likes and shares. As infographics take more time to create than just simply uploading an image, busy website owners are prepared to pay for custom infographics. And don’t worry, an infographic can be created using simple design software such a Canva. So extensive graphic design skills are not necessary, just a creative eye.
Copywriting. Bloggers and business owners are out there looking for freelance writers to help them with their internet marketing campaigns. If you can write a good video marketing script, sales copy, press release, product reviews, website content and advertising copy, you can make money doing exactly that. You may need basic SEO skills since most of these copywriting jobs require some knowledge on how search engines work. These people are looking for traffic, and they will only hire you if you can deliver that.
Smoking is on the decline, but those still hooked on tobacco will pay almost anything to satisfy their nicotine habits. The same is true for drinkers of caffeinated beverages. Appealing to vanity is another lucrative business. Think of all the money spent on face creams, hair coloring, botox injections, body-slimming gyms—and all the gorgeous clothes to fit on those magnificent bodies.
Tools & Resources: I’ve written a pretty comprehensive guide on the best web design software that covers both free and premium software packages. If you’re serious about becoming a web designer, then I recommend purchasing the full Adobe Creative Cloud Suite. At $49.99 per month, this is probably a bargain considering what you can achieve with this set of tools.

There’s an excellent chance that you have one or several musical instruments sitting in storage that haven’t been used in years. Perhaps it’s a leftover from when you were in school, or even from your days playing in a band. Whatever the reason that you have it, it’s probably worth money if you can sell it. Brand-new instruments are ridiculously expensive, so people often look to buy used equipment instead, particularly if they are novices.
