I have promoted my store on Facebook severally, I see traffic but no sales. There are quite some abandonment that should had been orders. Initially, I had a challenge with my payment gateway and that had been sorted. Should I change the products in the store if I should what will you recommend. Please assist.
I think you should create a Shopify store (If not yet) besides a Facebook store.
Selling on Facebook is a good choice, but you can not install a push notification App on this plaform to recover abandoned carts. Creating a store on Shopify and you can install a push notification App such as Ecomfit that helps reduce cart abandonment and improve conversion rate on your store.

Anyway, keep running your store on Facebook. I hope this is useful.
