Which marketing channel did you focus on after your first ProductHunt launch?

We launched Curatora.io for the first time on ProductHunt and acquired over 200 users who signed up for our 30-day free trial. We received a lot of good suggestions and feedback from real users, which helped us to improve our product. Discovered good bugs that we had missed during our own testing.

Now we're wondering: what should we focus on next? Which marketing channel should we work on? We're thinking of two things:

1. Spending time on inbound marketing and generating good content for SEO.
2. Work on direct sales, LinkedIn outreach, or cold email.

What have you done to acquire new users after the first ProductHunt launch? We'd love to hear any suggestions or advice!
