I am in the process to start Product Development for E-commerce and Online Retail domain but before starting I would like to know what are the biggest challenges faced by current state of Art E-Commerce Application ?
Also I have not experience building e-commerce products and so what things should I keep in mind before developing one ?
Is there are books, articles, blogs outside which I should refer to gain some knowledge before starting out ?
Update: What are you thoughts on the recommendation engines for ecommerce applications ? What challenges we have with current state of recommendations engines for ecommerce web application and how can we overcome them ?
