Why is my eCommerce store not getting any traffic or purchases?

hey

I built a Shopify store, I paid for a domain so that (it would be mine) I promote on your Facebook and Instagram with videos after receiving approvals if necessary I also promote on Google Maps I do campaigns for a 10% discount if you sign up for the news (to receive emails from buyers) I only get paid through PayPal which was reliable, I write articles for the blog, but:

I don’t get any traffic to the account, no purchases, just one email from a woman who did me a favor by checking the whole story for two years, can someone please help me?

Thanks Meital
