It’s our view that there’s no true set-it-and-forget-it, totally passive business idea. But at the same time, there are many passive income business ideas where you perform work once and then benefit from that work over and over again. Take blogging as an example. There are posts on your website that are a few years old that will continue to generate revenue from advertising and affiliate marketing sales. It’s for this reason that blogging tends to be one of our favorite semi-passive income ideas. Creating an informational course, earning recurring affiliate commissions, and stock photography are among other lucrative passive income opportunities.
