Use this blog as Guide to prepare for the holiday shopping season. It is a collection of Best Practices we captured from our previous and current engagements with eCommerce veterans and startup sites that managed to get through the previous holiday seasons without major hiccups. The main goal is to ensure high conversion rates. In order to do this you need to test the important landing pages, conversion funnel actions as well those web services that are called from your (if you have it) mobile application. Testing must also not only focus on server-side but must include CDNs, 3rd Party Plugins and external services.
