Find a profitable niche: We’ve talked about this a lot. But, where are you most comfortable. What niche do your skills, values, and interests intersect? Do you have 10 years of experience as a technical writer? Do you have long-standing PR relationships that’ll be invaluable in helping startups launch a successful crowdfunding campaign? Determine what makes your value unique, and lean heavily on showcasing that strength to your potential clients.
Get ecommerce software. You'll need this so your customers can view your products, enter their information and make a secure purchase. The software safely stores customer information. Don't skimp in this area, since the ecommerce software you choose will make a big difference in how easy it is for customers to feel secure buying something from your store.
Do you have a big ticket item or two that you only use part-time? We are living in an age of “peer sharing” which has opened a door to earning income from renting everything from RVs (Outdoorsy) to sailboats (see Sailo). This works for smaller items, too. KitSplit lets you lend out professional cameras. If you have a desirable item that costs more than the average person can afford, someone out there may be willing to pay to borrow it.
Craigslist: Craigslist is definitely the scrappiest of the major online resale options. The advantage of Craigslist is its enticing profit potential, thanks to the total lack of listing and selling fees for most items. The disadvantages are many, but include potential safety risks and higher chances of nonpayment. If you do choose Craigslist, keep your wits about you and use the buddy system.
If you’ve ever thought that buying and flipping real estate seemed fun and lucrative, you’ll love the concept of buying and selling domain names. Just like buying low and selling high with actual homes, domain name flipping has big margins that can put a lot of cash in your pocket. The most expensive domain name ever sold is insurance.com, it sold for $35.6M back in 2010. To buy a domain, you need little more than a credit card. You can purchase domains on familiar domain purchase sites like GoDaddy.com, or on domain auction sites like NameJet or Sedo. Selling domains require a little bit of creative thinking, since you need to find the right buyer (much like selling physical real estate). Successful sellers will tell you that creating a portfolio of dozens (or even hundreds) of domains increases your chances at making sales and profits. There are hundreds of auction sites and forums dedicated to buying and selling domain names, so you can easily find tips and tricks from people who have sold domains for tens of thousands of dollars. That said, not every domain is a diamond in the rough, so patience is the name of the game.
Consider your expertise. If you take the time to reflect on your experiences, you will realize that you have more knowledge about which to write than you might think. Begin by listing three assets that define you, such as your profession, a special hobby or a personality trait. Next, list three things that inspire you, such as religion, education or charity. Finally, list three of your dreams, such as getting married, traveling or spending more time with your children. These three lists should give you many ideas of topics about which you can write.
If you want to clear some space out in your house and have a big stack of books you’ve been holding onto for too long, you can make money selling your books and textbooks online.

When creating a membership site, always offer different plans and pricing tiers to appeal to your different categories of audience. Access to specific types of content is then dependent on the plan selected by a member. Membership fees can be a one-off payment or a repeat subscription.

If you're ready to be in charge of your own destiny, but don’t have the capital to buy a franchise or open up a storefront, consider starting an online business.

However, like with any business, you'll need an excellent product and a solid marketing plan. See Step 1 to learn what it takes to start your business online.
Use your home to work from home. If you live in an area where there is a demand for short-term rentals (like near a university or the downtown of a large city), you may well be able to find renters by networking in your community. However, with the rise of Airbnb and places like it the Internet has once again made it much easier to make money from home. Using these sites you can rent out a private room, shared room or even your whole house for a night or month or whatever period of time you like.
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.
