How do I promote by book??

Hey! So my debut novel is coming out in a week. I’m trying to figure out ways to promote my book the minute it comes out. I already plan to do ads on Amazon, as well as buying one or two promotions in CraveBooks (if you’ve used it before lmk which one is best!!), and obviously posting on social media. I’m able to spend around $200, any suggestions would be appreciated greatly! 😁
