What is the best way to get sign ups on my coming soon page?

Hey everyone! I am launching my product in about two weeks, and have been wondering what methods there are for getting more sign up on my coming soon page. I have already promoted it to my audiences on social media, but did not have a large following to begin with. I found that many people that match our ICP did not have product hunt accounts, and so they failed to sign up since it was too much work. What are some good ways to grow an audience of product hunt users? Thank you all in advance! Greatly appreciate the help!
