"Design your product description page including related products…"

Make shopping easy and people will buy more. Design your product description page including related products that customers might like to buy.

A good design example is the Abercrombie & Fitch website, is you are looking for shorts it will show you a shirt and shoes to combine them with on the "Complete The Look" section.

Making this kind of integration takes time as it requires to internally link products, but all this effort could be extremely rewarding. Read other Design vs Art articles about Compulsive Shopping and Product Recommendations.

Compulsive shopping could be recognise as an addiction that make retailers happy. They just offer customers things they might like to buy. At the beginning of the internet shopping many thought that compulsive shopping would disappear in the online era, but reality is very far from those wrong predictions.

Compulsive shopping could also be promoted online, some online retailers are doing it better than others thanks to a better design. For example Nordstrom is doing it well, recommending users similar products.

Yahoo! Shopping gives users a lot of valuable information about the products and also recommends alternative products for those with poor user rating. In this example, I was checking a digital camera that has only a 2-stars rating, so Yahoo! shows me similar products other users were looking at.

Amazon goes one step farther and asks users to rate some products bought recently to use this information to make better product recommendations. It can not be better, once again Amazon is doing very good.
