10,000 impressions, 3 ATC, 1 Conversion – Conversion Objective (Tiktok + Meta + Pinterest)

Hello! Our store -> ChiorJewelryOutlet.com

We are currently driving traffic to the product pages directly to find a couple of products that convert better than the others. All of the products are genuinely on sale for 80% as we're trying to clean our stock, we do not dropship. We tested the prices on all products: $100, $300, and $500 and nothing seemed to work.

Apart from a review app/testimonials, is there anything we can do to improve our design/customer buying experience that will result in a higher conversion rate?

Thanks!
