I launched a SaaS product recently, and after a pretty successful HN launch, I've been trying different ways of marketing.
What I learned, and this may be obvious to many, is that the boring path of getting users by gamifying SEO actually works. I firmly believe that you can get your first 1K visitors by just using the formula of writing content. You don't even have to be good at writing -- target some keywords, use good SEO hygiene, have a high enough word count, and people will at least come.
I pumped out some mediocre blog posts with clickbaity titles [1] just to test it, and I was surprised to see it work, bringing in consistent weekly traffic. A popular Chinese blogger including a one-liner about my product in his blog in February is the sole source that brings ~1-2 Chinese users (actually signed up) to my app every day 3 months later.
