Be social. Whatever your business, whatever your venue, keeping your name in the air is key to internet success. Have a business account on Facebook, Twitter, and LinkedIn. If your business is graphically oriented, have accounts on Flickr and Tumblr as well. Whenever there is news of any kind—a new contract, a new page, a new entry, a new photo—cross-post it to all your social media sites. Also make sure those sites link back to your main website, and that your website has links to all of them.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
MyPoints is one of my favorites. You can earn up to 40% back on all your purchases at 2,000 top retailers like Walmart, Home Depot, Best Buy, and Amazon. They also offer promo codes at tons of online stores. One of my favorite things about MyPoints is that you can redeem your points whenever you want. All you have to do is can cash out and get gift cards, or you can transfer the cash to your PayPal account. It’s actually very easy.
Become an Amazon Associate and then use Keyword planner to find an in-demand niche: With more than a million different products to choose from and up to 10% commission the sales you drive, Amazon’s affiliate program is a great place to get started.

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).
Websites like Care.com connect parents with babysitters. The company does all the background checking and other due diligence to put parents' minds at ease. Of course, you can appeal directly to people in your personal network, but if you're looking to generate recurring revenue sign up with a site marketing to parents looking for child care services.
– Project Payday is one of those sites that has testimonials of people who have earned thousands of dollars by getting paid to get trial offers. I’m not saying you’ll earn thousands, but it is legit and you can earn some extra cash. They assume that by paying you to do a free trial, you’ll either like the product and purchase it, or forget to cancel the trial and get charged for it. If you can keep track and cancel before you get charged (if you don’t want the product), then this is a great site for making some money.
