Are you truly finding valuable customers from Product Hunt after launching your product?

Not really to be honest. It seems like Product Hunt and the value it provides has really changed over the past 5 to 6 years.

My products are articles in my blogs.

We are looking for actual testers of our product but I think it is very hard to find someone on ProductHunt

Unfortunately, no.

I had a few sales from ProductHunt traffic after launching but they seemed more curious than serious buyers. Getting featured helped boost credibility which led to some valuable customers from Google searches later. The key is nailing your messaging to attract the right audience. ProductHunt alone won't carry you but it's a nice initial boost if you position your product well.

I've gotten a few sign-ups and paying customers from my PH launches, but nothing game-changing to be honest. I think it's a great place to get some initial exposure and feedback, but you'll likely need to do more marketing beyond just PH to really grow your customer base, especially for articles/blog content. SEO, social media, email list, etc. are probably going to be your best bets longer-term. But every bit helps, so I'd say launching on PH is still worthwhile! Just keep expectations realistic.

A few key customer came from our launch, but most traffic felt more like curiosity than genuine leads.

I haven't launched yet. I am planning to launch in the coming days.
