I suggest focusing on the "related products" and "similar products" sections, these sections are very important, they increase the total value of the order by at least 30%. Very frequent customers add more products from these sections. Currently they are not very efficient, and there are several main reasons: 1. limited to the number of products, they can only show ** number of products and then nothing. All products are generated as soon as the page loads, which adds unnecessary HTML code that slows down loading. I suggest making an "infinite scroll", and with each click of the "next" arrow - dynamically with Ajax to load the next ones, this will greatly speed up the loading of the site, it will also allow the customer to browse many products and add others to their order.
