Personalisation. Its on the top of every marketing department's shopping list, but what does it actually mean? Here we define exactly what personalisation is. We'll evaluate the different types of personalisation, looking at how and when they should be used. Most importantly we lay down the strategy thats needed to personalise effectively and to produce results (jumping in headfirst WILL have have bizarre and unintended consequences). We'll look at just how important the research, user experience and design processes are when planning a personalisation strategy and we'll delve into the tools and plugin's that can be used to implement personalisation on an Umbraco website.
