Consumers nowadays purchase a variety of products in online shops for different reasons. Certain products involve high involvement decision-making with low purchase frequencies in general. At the same time, virtual shelf space is unlimited and consumers face a variety of products, which exceeds their rational capabilities. This condition requires online shop operators to implement search tools in their web sites that allow consumers to structure and reduce complexity, both on a catalogue and a product level. Consumers in general do not always possess product expertise, especially in the case of low frequency purchases such as digital cameras. Virtual product advisors intend to fill this gap.
The primary objective of the thesis is to investigate the interaction effect between different levels of consumer knowledge and a chosen product search approach. A special focus is put on a virtual product advisor and a facet search as a structuring tool. Based on theoretical work in marketing, psychology, information system management a set of hypotheses was developed pertaining to the interaction effect and how it affects the perceived quality of the online feature of
a product search interface from a consumer perspective.
A randomized experiment with a control group design in a live Online Shop was conducted to test the hypotheses. In sum, the findings suggest a contingency between the consumer
knowledge and a product search interface in regard of the impact on antecedents of esatisfaction. The results provide two different angles from a marketing perspective in terms of
usefulness and from an information system management point of view in terms of usability.

Objectives and Research Themes
This thesis examines the interaction between consumer knowledge levels and specific product search interfaces (virtual product advisors vs. facet search) in online shops. The primary research objective is to determine how these search approaches influence the perceived quality and e-satisfaction of consumers, focusing on their ability to structure and reduce complexity during the decision-making process.
- Interaction effects between consumer expertise and product search methods
- Perceived usefulness and usability of online product search interfaces
- Application of the WebQual framework in an e-commerce context
- Impact of search tools on consumer e-satisfaction and decision-making
- Empirical verification through a randomized experiment in a live online shop
Excerpt from the Book
3.3. PRODUCT SEARCH APPROACHES
Basically four different search interface possibilities exist. In the course of the paper, the search interfaces are termed product search approaches (PSA). In practice, the use of only one type is hardly found, because the combination of the various approaches offer a more natural costumer experience regarding the search process as well as better or more effective product search results. This is referred to as a hybrid search serves as a triangulation to a search task by combining different advantages of the various methods. Nevertheless, in order to understand hybrid search, the pure archetypes of product search tools shall now be defined. Excentos’ Whitepaper on Guided Selling (2011) offered a good overview of the various search methods existent in the online marketplace.
Local Keyword Search or Full Text Search is an interface, that offers a possibility to directly type in strings. The search engine matches the search query with hits in the full text contents as well as in the online shop taxonomy such as product tags, categories and datasheets. Usually the result list is indexed through a ranking logarithm and the best matching results are presented on top of the list, whereby the ranking depends on different variables such as keyword counts, average space between keywords etc. A ranking logarithm can be comprised of a multitude of variables and the relative importance of the variables can be determined idiosyncratically, thus it represents a domain of proprietary technology. A very popular plugin or widget is the Google Custom Search for Websites which offers webpage operators the possibility to integrate Google’s search engine to ‘crawl’ local content.
Hierarchical Category Search “hierarchically organizes individual (..) categories and characteristics, starting with general main categories and moving down into sub-categories that branch off from the main categories. The list of results is filtered according to the sub-category that is selected.” A Hierarchical Category Search can be regarded as a decision tree with varying degrees of detail among its branches or respectively the amount of subcategories.
Summary of Chapters
