Define your product or service. Starting an online business gives you the benefit of having access to millions of customers, but you also have a lot more competition. No matter what you're trying to sell, you can bet that hundreds more online retailers have a similar idea. What differentiates your product from other similar products? To help your product stand apart from the rest, you'll need to find a niche.
Teaching and tutoring English as a second language is a great way to make a solid side business idea work, not to mention opening doors for you to travel the world if you'd like. While full ESL (English as a Second Language) accreditation is recommended, as long as you’re a native speaker, there are people in countries such as Hong Kong or the UAE who are willing to pay upwards of $25/hr for you to teach them English via Skype. Indeed, Learn4Good and Remote.co often have remote english tutoring jobs posted, check back frequently. Then once you land that remote job, you'll need somewhere more professional than your dining room table to meet with students—check out this post about how to find places to work remotely and you'll officially graduate this side business idea into a full-time endeavor for yourself.
But it’s also easier for consumers to compare similar products, which makes your ability to differentiate yourself more important. For instance, if you decide to use Etsy to sell handcrafted cutting boards, when a potential customer searches for cutting boards on the site, they’ll wade through potentially hundreds or thousands of relatively similar listings.
Driving for one of the two globally expanding app-centric taxi alternative services, Uber or Lyft can still be a fairly lucrative way to earn money as a side business idea on nights and weekends—working only when you want. But before you dive head first into this side business idea, do your homework and calculate the costs of extra gas, mileage, tires, wear & tear and usage on your vehicle—it's not a guaranteed business idea that'll turn a huge profit every weekend.
There’s more to being a coach or personal trainer than just being fit and loving to exercise. Finding a specialization is important, and licenses might be required for certain types of coaching roles. For instance, a friend in Boston obtained US and European soccer-coaching licenses before opening a successful one-on-one soccer-instruction business.
