Hey, I have reviewed your store. Here's the thing; Paid traffic is nothing more than an amplifier. It's all about sending the right message to the right people and at the right time and to the right destination that is your website. Now if that destination (website) fails to deliver? What if that destination isn't congruent with the promise in your ads?
This creates a bad experience, right? And Bad experience= No sales. Your prospect's attention span is short, so you have to be quick on the ball. Once they land on your product page you have to convince them to stay there in the first seconds otherwise you lose them for good. How do you engage your customers in your store? You should try giving Loyalty Points to customers when they visit your store or when they make a purchase or when they leave a review. I see that you have a lot of reviews on your store so why don't you give your customers loyalty points when they leave a review on your store. This will double up your sales.
