needing a tiktok ad expert

i own https://princesshaven.com and i've been running 5 ads with a ctr of .6~ and so far ive spent 300$ which i know is not much but i only have 2 conversions which were checkouts but no purchases. i lowered my prices, i believe my website is decent enough to attract people but im terrible with the ads that i make. I am open to other platforms to sell on as well
