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.

eBay is the most popular global auction site around and is a great place to sell items you no longer want. If you are looking to earn some extra cash, start out by looking around your house for things you no longer want; list them on eBay and watch as customers bid on them. You can also purchase clearance sale items and thrift store finds and make a couple dollars profit by listing them as well. The key to selling on eBay is to do your research and find out what the hot items are.
Another way to utilize your talent and business skills is to run corporate workshops online. Businesses are always looking for unique ways to help educate their workforce, and if you can package your talents into a day or half-day long session, you can sell that to companies all over the world to make money online. Start by building a portfolio and then reaching out on LinkedIn to influencers at relevant companies to see if they would be interested in you teaching their team.
Do a bit of research and due diligence. How much are people renting out their homes in your area on sites like AirBnB? What’s the going rate and just how do those homes compare to your own home? There are a lot of issues to cover if you’re thinking about doing this, so don’t expect to profit simply from it. The more care and attention you put to the finer details here, the better it will be.
I’m looking for people to join my team with Advocare! It’s a great opportunity to get healthy (especially as the New Year approaches!) and make some additional money! I make a couple hundred dollars extra each month and save on my own orders! I feel so strongly about the program I’m willing to pay people’s start up costs! Email me with “advocare” in the subject line if you’re interested!
Hold a yard sale. If you have a yard or garage and plenty of items to sell, you can have a yard sale as early as tomorrow. By advertising your sale on local Facebook pages and Craigslist, you can also skip the paid newspaper ad and keep all of the profits for yourself. If you don’t have time to price everything, try asking patrons to “make an offer” or grouping similar items on tables with an advertised price (e.g. everything on this table is $5).
I make the bulk of my money from blogging. In addition to the advertising revenue streams mentioned above, I also receive flat rate payments for blogging from various blogs throughout the web. I’m paid to write as a whistleblower, financial analyst, reviewer, commentator, and more. Writing for other sites builds traffic to my personal blog. The traffic for this blog gives me clout to present to advertisers.
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. 
Last but not least, you can also earn money online by building an online community, although the monetization strategies you can pursue will vary a lot depending on your goals. You can build a community with a blog, for example. You can also build an online forum and charge people for membership. You could even build up a Facebook group and use your influence there to sell and promote products.
