Pay Per Click (PPC) Question

Hey! Relatively new seller here. I am running PPC, about $100 (dont have a lot of capital to play with). I am noticing about 5-6k impressions a day and about 15ish clicks a day.

Since running ads, about two weeks ago, I’ve made 2 sales. Regardless, I am at a loss because ad spend is high. My product is in the food category, so price is about $14.95.

How can I make these ads worth it and convert more? Should I look for a different keyword?
