A lot of credit goes to IH. Sharing some tips:
Launch on Tuesday. Historically, Tuesday has the most votes. Even if you don't get #1 of the day. More people will see your product. If you want to get product of the day and don't care about overall traffic. Launch on Sunday.
Share the launch on Twitter, Indie Hackers, Slack, LinkedIn and your email list.
Don't ask for votes. Ask for comments and reviews. The former gets you disqualified.
Respond to comments. This factors into the algorithm.
Get someone with a large following to hunt you. Their followers get an alert when they hunt a new product. (EDIT: Debate in comments but verified, by @hieunc, that this works)
That's it. The previous milestone mentions PreviewHunt and how to land on the first page.
