If you want to offer Guided Selling for self-explanatory products, such as books, clothing or furniture, in your online shop, then it is important to offer the product selection preference-controlled, using tags. With these products, a customer recognises without visual filters what, for example, “short sleeve” means. Thus, the different products displayed on a shop page can be identified by different tags. By clicking on the preferred tags, your customers refine the list of results until they have selected the right product. For example, if a shop customer clicks on the tags “short-sleeved”, “black” and “cotton” in the category “T-shirts”, the results list changes immediately with regard to this tag selection. Which products and tags are displayed depends on the click and purchase behaviour of the respective customer. In addition, Guided Selling also offers alternatives, e.g. if all black S. Oliver T-shirts in cotton were displayed, T-shirts from Tom Tailer can be displayed that are similar to S. Oliver.
