TL:DR; There's no Product Hunt support on weekends - be careful! And if something looks wrong, reach out and ask questions, the PH support team is awesome when they're there!
There's a million bits of generic advice about launching on Product Hunt. We initially launched yesterday (Sunday), but despite being #2 for the first 8 hours, we never got put on the homepage! Because it was Sunday, there was no Product Hunt support all day, so we were stressing for ages.
But it wasn't our fault, but a technical thing about how products get onto the homepage. After a few stressy Twitter DMs, Intercom chats, and an email to email@example.com, Product Hunt relaunched us today. Here's what to avoid:
1. Be really really careful launching on weekends - there's no Product Hunt support to help you if things go wrong
2. If you're in the top 5 by total upvotes, but you aren't on the homepage - just reach out! Product Hunt might re-launch you, which for us has totally saved the day.
