Our client TescaraHats (name changed for commercial reasons), a European market leader in manufacturing customized hats, set up an e-commerce site in hopes of increasing its market share and boost its sales. This did not happen. TescaraHats learned quickly that there is much more to e-commerce performance than simply putting an e-commerce service online. In Parts 1-3 of our e-commerce performance mini-series we discussed why focusing on page rank is not enough and that we should look at your performance at the back end and potential network-related problems.

Unfortunately, additional SAP training cannot solve all the problems. Separately and unrelated to the training issues, Fonterra started to notice that end-t... (more)

Five Steps to Improve E-Commerce Performance for Increased Sales

The saying "if it doesn't exist on the Internet, it doesn't exist"[1] is ringing truer every day.

In this blog series, I have come up with several ways to ensure your company's e-commerce performance success, including: avoiding unnecessary network load,reducing number of (internal) HTTP errors, improving backend performance,understanding your clients, ensuring scal...
