My today's PH Launch got Tanked: Got Any Advice?

Hello IH,

I've built Eurekea to help IndieHackers find ideas for their next hustle. It's offering a dataset of 250K+ SaaS, Apps & tech-products launched in the last decade.

Here's the link for PH page: https://www.producthunt.com/posts/eurekea

My previous posts on IH & a few subreddits on its pre-launch were good & even got my first paying customer from IH.But today's PH launch has been a total flop.
Maybe it's their algorithm-though I did everything by the official PH launch guide(this is my 2nd PH launch, the first one got a pretty fair response).

Could you help me figure out what am I doing wrong here? I've still got about 14 hours of PH left.
