If you have 1 day for traffic

"You have one day and $0 to bring some some traffic to your product."

What would you do:
a) Write an article on Dev.to and crosspost on Medium.com
b) Lookup 3-4 relevant hashtags and get involved (or drained) in relevant Twitter threads
c) Share a personal story about your product on a few Subreddits and Facebook groups
d) Share a technical part of your product on Hacker News
e) Optimise keywords for SEO (because there's no other way)
f) Write a lengthy post on how you failed to do so on Indie Hackers (jk)

Maybe something else?
