Everyone (even kids and retirees) need to have some level of technical know-how to stay competitive and appreciate the marvels of the digital age. Just observe how learning sites like Codecademy, Treehouse, and Udacity continue to grow and you’ll understand the urgency of getting computer training for our generation (thus making it a great business idea to train others if you already have the skills). If you’re a techie, you can cash in on this need by offering lessons and tutorials within your neighborhood or across cyberspace through portals like YouTube or Udemy as a side business idea. You can even set up your own tutorial site with an interface for online payments.
The key to success in this business is being very disciplined in buying. Limit your car buying to popular models that you can turn over quickly, models that you have a strong understanding of current local pricing on, cars that you can buy at a significant discount to the price you believe you can fairly sell them for, and cars that are highly unlikely to need major work.
The first step in getting a top ranking in the search engines is to submit or suggest your site to them. In other words, you have to provide them with details about your small online business site. You want to make sure that the “spiders”–automated programs that crawl the web indexing sites for the search engines–find your site and include it in the search results.
Social media is an integral part of any business but it’s time-consuming and ever-changing – so really quite difficult to keep up with and, more importantly, capitalise on. Many business owners are willing to outsource this time-intensive task, so it’s a great opportunity for social media fanatics. Bundle together a few interesting offers, such as “Startup social media kit” or “Small Business Social Media Starter Kit” that encompass everything from social media graphics to analytics reports and the seamless experience will bring you more clients than you expect. 
Mild spoiler alert: Viewers of the TV drama Orange Is the New Black might remember that the show’s main character made amends with one of her fellow prison inmates by making her a soothing lotion. Hopefully you won’t find yourself in prison, but if you find yourself wanting to start a home-based business, consider hand-making soaps and lotions yourself.
Another big suggestion is finding small and easy ways to test business ideas and assumptions. I think this is implicit in your post. For example, if you have an idea for a digital course, you may do a free webinar on the same topic first. If you can’t get enough people to show up for a free webinar, then there probably isn’t enough interest for a paid product on the topic.
As a result of these and other factors, an estimated 40 million Americans now work from their homes. This number includes employees working from home for a larger employer as well as self-employed. Not surprisingly, two-thirds of home-based business owners are women, who choose this option either because of childcare concerns or because of a perceived glass ceiling limiting their earnings potential in the corporate world. Running a business out of the home offers a number of advantages, including time savings, control over working hours and conditions, independence, and flexibility. Starting a home-based business is also considerably cheaper than starting a business in rented facilities. In addition to saving money on overhead expenses, commuting costs, and wardrobe expenditures, many home-based business owners can deduct a portion of their rent or mortgage interest from their personal income taxes.

The home office deduction may become even easier to use in the near future. Colleen DeBaise wrote, in an early 2006 article entitled "Locking In The Home-Office Deduction," about efforts being made to simplify this tax deduction. She wrote, "The National Association for the Self-Employed, a small-business group in Washington, D.C., supports a simplified, standard deduction to ease the burden on home-based businesses. And perhaps someday, sweet relief will be granted: Two bills introduced in 2005 contain language for a standard home-office deduction, although neither has passed. One of the bills, the Small Employer Tax Relief Act of 2005, specifically calls for a standard home-office deduction of $2,500'¦. In the meantime, small-business owners have little choice other than to muddle through the form—or hire a tax adviser for help."

With nearly 100,000 different custom extensions both free and paid available in Google Chrome's marketplace, there's a huge opportunity for creating a useful extension for people to use while browsing the web as a low effort business idea. One of my favorite Chrome extensions, Yet Another Mail Merge, which enables you to send bulk customized emails from within Gmail, gives you 50 free credits to send emails and gives you the chance to upgrade to a paid account to unlock more sending—a great upsell for the people who are getting value from the extension. Even free Chrome extensions like SVRF Tabs by SVRF, which replaces your new tab with stunning VR and 360º images, have the potential to bring in new users and eventually drive revenue for the startup's core business. Another fun example from a friend of mine, Kathleen Garvin, is Hide images with NOPE, a Chrome extension that hides images on the web pages you're browsing—to help eliminate distractions and keep you from seeing images (like those of certain politicians) that you may want to hide. This side business idea is particularly great because it also allows you to showcase your development skills—which can be put to work as an adjacent side business idea on a freelance basis alongside the Chrome extensions you launch.
If you’re the sort who takes apart the computer for fun, operating an electronics repair shop out of your home is a natural decision. In particular, repairing iPads and other tablets would provide you with a great deal of business, as many tablet users are looking for a less expensive way to fix smashed screens and other damages that can be costly through the manufacturer. Median salary: $49,170.

Raw Generation is a raw juice company that launched its ecommerce store through Shopify, only to experience little success in its first 6 months. But you know what they say, where there’s a will there’s a way, and owner, Jessica Geier, was determined to find it. Raw Generation used deal sites to take the company’s monthly revenues from $8,000 to $96,000!
Yet another common problem encountered by home-based business people is frequent distractions that reduce productivity. In fact, distractions are everywhere for people who work from home. When faced with a difficult work task, it sometimes seems far preferable to run the vacuum, clean out a closet, walk the dog, have a snack, take a nap, raid the refrigerator, pull some weeds in the garden, or do any of the myriad other things that need doing around a normal household. In addition, people who work from home lack the motivation that peer pressure can provide in a regular office. They also face spouses and children who demand time and attention, as well as friends and neighbors who call to chat or stop by to ask favors.
