The importance of product pages and their design on an ecommerce site should never be underestimated. They are that final push, the last chance to convince your customer that the product they are looking at is the right one for them.
The first and most essential aspect of designing any product page is simplicity. A customer wants and assumes that the product page will be focussed on just the one main product. Allowing users to find items that might better suit their requirements through the use of recommended products is great and is always encouraged but it should never compromise the prominence of the selected item. The clarity, weighting and flow of product information is also integral to how a customer expects to experience a product page. By ensuring that the title is large and at the top, flowing into clear pricing information, stock levels, product options and then a very clear buy button means that all of the really important details are above the fold on most browser windows, regardless of size and resolution.
