There are tons of different ways to market your side project and what works for someone else may not work for you, of course.

I think it really just comes down to where your potential customers may be hanging out / searching. For my side project, I've had decent success responding to posts/questions on sites like Quora, where someone is looking for exactly what you offer. It's free too (besides for your time!).

The book Traction (https://www.amazon.com/Traction-Startup-Achieve-Explosive-Cu...) gives a pretty solid overview of different marketing methods/strategies.

Tapping into an existing, niche community seems to be a pretty common and successful method. Does your project help solve a common problem for a narrowly defined group of people? If so, is there a forum where this problem is commonly discussed? Become a helpful member of this community. Ask and answer questions there without only constantly pushing your project in a spammy way.

That is a very good idea. The side project I am working on does serve a very specific function, so I may try taking this route. Now, do you answer old questions, or do you find new ones and answer those?
