Why are my sales low despite running Facebook and Google ads?

[xGafel]

Hi, I opened my store around 3 weeks ago but for now, I have a few sales, I already set up some Facebook ads and Google ads and I have viewed (1589 sessions, which I know is not so many I think )with not-so-match sales, can someone give me tips, please?
