18. CraigsList – Some things don’t ship very well. Other things may make you feel uncomfortable to sell to someone across the country. Anytime you’re selling a large item or something you just don’t want to ship, Craigslist is a great place to go. It’s simple to list your item (again, take good pictures!). If you don’t like the idea of putting your phone number out there, the interested individual can send you a message to your inbox without even getting your email address.
Make money selling handmade crafts if you love being creative. Turn your hobby into a side business. Whether it’s homemade candles, friendship bracelets, or pretty cards, sell your crafts at a local craft fair, farmer’s market, or online on Etsy. Price your goods by considering how much you spent on materials and how long it took you to make each product.
Host a yard sale to get rid of things you don’t want anymore. Clean out your room and gather up all of the toys, decor, and clothes that you no longer use or want. Display your items on a folding table in your yard or driveway with your parents' permission. Put prices on each piece with a sticker label based on what you think it’s worth and the original price of the item.
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. 
One great way to get ideas for related products to promote is to look at the stats/reports that Amazon gives you to see which products readers are buying. After a while you’ll start to notice that they’re not only buying the products you directly promote but other products as well. Some will be completely irrelevant to your niche – but many times trends will emerge that could signal other products that it might be worth promoting.
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. 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.
Whatever you choose to do with this monetization and marketing technique, take time to plan your strategy. While it is very easy to get started and to add Amazon affiliate links to WordPress, the key to success is in how well you execute those links and promote them to your visitors. Affiliate marketing takes time to excel at, so be patient and don't give up!
“Great list! I especially like the tutoring stuff. I’m good at Math that’s why I tutored once for my godparent’s 8th grader. I had fun with the her and her mum cooks the most delicious brownies. I don’t think I can donate a plasma or be a human guinea pig. But maybe you should add herb and vegetable planting. This job doesn’t require too many technicalities and is so far the easiest thing to do. There’s a method called square foot gardening for those who don’t have big spaces. It’s so simple to do and gardening in small boxes requires small maintenance. There is plenty of information on the web about how to do so. Once you get growing you can even sell your fresh produce to your neighbours at a cheaper price, and earn some fast money in the process . P.S. I also would want to partake in an online survey. Some people recommended Cash Crate but I’m also curious about what happened to you?
8. Huge Array of Products — What initially attracted me to Amazons Affiliate program was the breadth of products that they had in their system. This is a great thing if youre niche is narrow or quite obscure as many niche marketers find it difficult to find affiliate programs to match their niche focus. Even if your niche is so narrow you cant find products, at least there are books about it. Not counting books, movies and music, Amazon has over 400,000 different products for sale in hundreds of categories and sub-categories.
I do this because I want to build a solid reputation and a loyal readership of people who trust me. I’d rather make less money and still have a reader than make lots of money and never see the reader again. For me, this comes not only from my ethics but my belief that in the long term building a good profile and reputation leads to other opportunities for profit.
The AAWP plugin conversion and CTR is amazing! Once I started to use the plugin on all my sites, I saw an immediate increase in commissions. It also makes my sites look much more professional. I love tapping into the Amazon API to pull images, make my own charts and tables plus I know I am abiding by Amazon's TOS. AAWP is a must have tool for anyone running Amazon affiliate websites!
