Write blog posts that clearly show the real-world problems that your software solves. People who Google for those problems, may find your blog post. And, if your software is actually worthwhile, then people will post a link to it here and on other forums.

Best of luck.

A blog post is a great opportunity to demonstrate the project without people needing to do anything (except read). That said, people using search will probably only see geeks for geeks, stack overflow, reddit, and a bunch of SEO garbage. Probably it helps to drop the link (noncringily) in discussions about that problem.

If you don't mind me asking — could you share which blogging platforms you recommend?

I live in Asia and only know local platforms, but since the user base is quite limited here, I'm looking for platforms where I can post in English and reach a broader audience.
