Get paid to search the Web. Sites like Swagbucks.com and Zoombucks.com will pay you to use their online interface to search the web. To qualify, you need to be willing to download their search bar and use it for everyday Internet use. The only caveat that comes with this “gig” is that you might be paid in gift cards instead of cash. If you can parlay those gift cards into items you need to buy anyway – like groceries or gas – searching online can be a lucrative way to spend your free time.
This is probably my favorite opportunity on this list because it’s really easy to get started and easy to make your first dollar.  Amazon has an affiliate program that allows anyone to sign up for an account and then earn a commission if someone buys something from Amazon using the special link they give you.  Usually, you’ll earn 8% of the cost of the item on Amazon but that depends on the category the item is in.

One of the cool things about Google AdSense is that it's so easy to get set up. If you have a blog or website, you can sign up for a free Google AdSense Account. From there, Google will give you a unique code that you will paste onto your website. Google takes it from there, tracking your page views, traffic, and earnings on your behalf. There is no upkeep or maintenance to get this thing going, which makes it a no-brainer if you have a website already.
1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.
Use Swagbucks for your online searches. Swagbucks is something I don’t use as much, but I do occasionally earn Amazon gift cards with very little work. Swagbucks is just like using Google to do your online searches, except you get rewarded “Swagbucks” for the things you do through their website. Then, when you have enough Swagbucks, you can redeem them for cash, gift cards, and more. You’ll receive a free $5 bonus just for signing up today!
In mid-2017, I sold my San Francisco rental property for 30X annual gross rent and reinvested $500,000 of the proceeds in real estate crowdfunding. I’m leveraging technology to invest in lower valuation properties with higher net rental yields in the heartland of America. With the new tax policy starting in 2018 capping state income and property tax deductions to $10,000 and limiting interest deduction on mortgages of only $750,000 from $1,000,000, expensive coastal city real estate markets should soften at the expense of non-coastal city real estate.

Get samples. When you first start out as a freelance writer, it can be hard to get work without any published samples. However, it is possible to get quality samples if you are willing to do some writing for free. First, you can publish content on your own blog or website. Also, you can write guest posts for someone else’s blog. Finally, you can write blog posts for free in exchange for a byline.[20]
Start a blog. Blogging is how I make a living and just a few years ago I never thought it would be possible. I made over $320,000 in 2015 by blogging and nearly $1,000,000 in 2016. You can create your own blog here with my easy-to-use tutorial. You can start your blog for as low as $2.95 per month plus you get a free domain if you sign-up through my tutorial.

This can be a little easier said than done, but if you have a large social media following, you can definitely earn money promoting a product or advertising for a company. You can even combine this with different marketing campaigns if you are an influencer and have your own blog (advertisement + affiliate income). This is how many bloggers make money! Again, it is not 100% passive but once set up correctly and then scaled, can be surprisingly lucrative.
You can also sell your own products. You can make music in Garage Band and sell it in iTunes, you could write an eBook and sell it within Amazon. You could also do your own crafts and sell them on Etsy or design a Tshirt and sell them on spreadshirt. Or you could do all of these things! Ecommerce is a great way to make passive income online, whether with a physical product or digital product.
I am an English major and a herbalist with so many ideas and no extra income to fulfill them. I recently started renting my extra apartment in the attic with Airbnb. It’s amazing how fast I accumulated some money for few hours of work between guests. Now I want to persue all my dreams of opening an online herbal store, publishing my ebook of treating Ulcerative Colitis with herbs, blogs, and videos, and pretty much all of the ideas mentioned here. I will save this article as its really helpful for whomever needs some ideas…
What is refer-a-friend? Essentially, you make money for using a service and telling others how great it is. Most of the times, you’ll get a unique link that you can share with friends directly or throughout social media. Whenever anybody clicks your link and signs up and/or makes a purchase, you’ll get a bonus. The bonus can be in the form of cold hard cash or an account credit.
Re-selling web hosting will enable you to make money hosting your own client’s websites. Large hosting companies like HostGator allow you to white label their hosting services. You could start your own hosting business or, if you are a web designer, include hosting into your web design packages. And the best of it is the hosting companies take care of the hosting for you, so all you need to worry about is selling.
Hello from the UK! Fundrise and Wealthfront are only available to US residents it seems :(. Any other readers from the UK here? The only thing I have managed to do from Sam’s list is getting a fixed rate bond (CBS is having a 5-year fixed rate at 2.01% – not great but the best I could find ). Don’t know if the FIRE movement will ever take off here but would love to trade tips/ideas on how to reach FI and have the freedom to consider alternative rythms to living.

Stock dividends: Some stocks, especially stocks from big corporate standouts, pay dividends to shareholders based on the number of shares they own, and the percentage of the stock price on the dividend date. For example, if a company pays out 3% on a stock that's trading at $100 per share, you'll earn $3 for every share of that stock you own. Add it up and that can be good take-home pay as a passive investment.
Many banks will give you a cash bonus just for opening an account with them. Talk about easy money!

Certain qualifications must be met but if you do qualify that's one easy way to earn $350 cash! Collect $350 cash with Chase Bank

There are several ways to make money from your car such as taxiing people, renting your car, or advertising businesses. Run the numbers before using your car to make money, especially if you're driving more than usual because it might cost more than you earn to use your car as a money-maker. Factor in depreciation, wear and tear, and gas expenses when you decide if driving is a cost-effective way to make extra money. 
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.
