What are the less talked ways to make money online?

Please share all the ways.

Software as a service (SAAS) has been widely talked about, but in reality, there are so many options with SAAS. You can do just about anything with that concept...so, I believe that the best ways to make money are ways that no one is talking about, while utilizing the SAAS methodology. Build something people need and make sure it doesn't already exist (or make yours the gold standard).

That's hard to answer, because there are so many methods to earn money online so picking one which is low profile isn't easy.

One suggestion from me is don't look for less talked ways, just look into yourself and work on what you can best do. If you are good at mobile app development, there is no point in trying to do something only because it is less talked.
