Any best practices for Product Hunt launch?

The best thing to do is to be genuine... I feel the main aim should be to get real feedback on your product/app, so that you can improve on it. You of course need to engage with people on PH as well as other platforms, so that you get people to try out your platform/app.

an easy-to-understand, descriptive yet powerful tagline. for me that's the most important thing for an effective launch.

sure, launching on product hunt is an art in its own right. first, think community, not just platform. engage, don't just broadcast. authenticity matters. be real about your journey, struggles, and little wins. create a compelling, relatable story around your product. people love stories, not just products. timing? crucial. know your audience and when they’re most active. your visuals: make them stand out but ensure they convey the story and functionality well. remember to guide visitors from product hunt to your actual product smoothly. follow up: express genuine gratitude to supporters and be there to chat. lastly, enjoy the ride. it’s as much about the journey as it is the launch. no matter the outcome, it’s a win if you learn and iterate.

Try to connect with more people and ask them for support.

Be active on Product Hunt. Find people, connect with them. Interact with other makers and show support. Also don't forget joining a couple of PH communities before the launch! And then get yourself a coming soon page you can share for support. Hope that helps!
