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.

If you already have a website or blog, look for vendors that offer related but noncompeting products and see if they have an affiliate program. Stick to familiar products and brands—they're easier to sell. For promotion, place simple text or graphics-based ads in appropriate places on your site; you can review or recommend products or create a dedicated sales page or website to promote a particular product.
