Knowledge Gain

How user knowledge gain is influenced by search engine marketing

Not only the search engine providers determine which search results we see, but also external influence groups. This doctoral research project investigates how knowledge gain of search engine users is affected by that.

Search engines are used by people to answer important questions, for example on health-related, political, legal, or financial topics. When searching, people usually examine only a few prominently placed results on the result page. These results are subject to considerable influences by paid search marketing (PSM) and search engine optimization (SEO). Both fall under the umbrella term of search engine marketing (SEM).

SEM measures are driven by commercial, political, or other motives, which suggest an influence on the quality of the documents and thus on search engine users. These influences are not yet addressed in process and selection models of information behavior. However, such a model is important to gain an understanding of the following:

  1. What quality of information is mediated through SEM?
  2. How does reviewing documents of different quality affect search engine users' knowledge gain?

The objective of this doctoral research project is to develop and empirically test an information-search-behavior model on the influence of SEM on knowledge gain. The project also aims to make a contribution to the search as learning body of research.
