Why can't I make my first sale despite having a well-optimized store?

[Mankatinle]

I’m struggling to make my first sale 

I started my store 2 months ago 

it’s already loaded with best hand picked products I searched this products.

my store seo optimization is done with most seo booster apps for Shopify.

ny design is unique and looks professional to me.

however I’m not making any sales I had 3 abandoned checkouts but send and email recovery for abandoned checkout where I reached these customers to come back and finish the payment for there order with and offer of additional 10% discount.

I advertised my products using social medi business accounts I’m currently using organic advertising where I upload vedios of my products through my social medi business accounts.
