Optimized conversions page but no sales

Hello, I have my shopify store since April 2024, online sales only. We haven’t had any sales in the year and we have tried everything. We have social media that has 800 followers only and we are paying google and meta campaigns. Traffic has improved up to 300 a day, but no sales, people stays between 30 and 40 seconds in the page but they are nor buying. We have a 50% discount and still no sales. Please give us any hint in regards of our problem. Our product is for a niche market because is made out of sustainable fabrics and fair labor in NYC and we offer unique transformable, convertible and reversible designs. We are a slow fashion brand. Thank you
