Start a bed and breakfast. If you live in a popular resort area or own a historic property, a B&B might be the perfect side hustle. Not only can you work at home with this career, but you’ll also score some tax write-offs in the process — although most innkeepers caution that the profession requires a lot of hard work and is more of an attractive lifestyle than a money-making pursuit.
If you are an expert on a particular niche topic and can assemble some of the best resources on it from around the web, then you can create topical hubs and get paid through sites like HubPages. You'll earn even more money by creating your own niche site, though. Established topic sites have a built-in supply of traffic and tools to make content creation easier and are among the most profitable online business ideas. Once you've established yourself as an expert within your niche, you'll be able to make money from a combination of ad revenue, affiliate fees, and more creative avenues like online courses, other digital products, and one-on-one coaching fees from others who want to learn directly from your expertise.
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.
