Most major Web search engines typically present sponsored and non-sponsored results in separate listing on the search engine results page. In this research, we investigate the effect of integrating both sponsored and non-sponsored results into a single listing. The premise underlying this research is that searchers are primarily interested in relevant results to their queries. Given the reporte...

The analysis to date of sponsored search auctions, originally conducted by Varian and independently by Aggarwal et al., has yet to describe more recent developments such as the emergence of interacting advertising exchanges. This paper assess the significance of such phenomena. Building on Gonen and Vassilvitskii’s model of sponsored search with reserve prices we depict advertising networks as ...

The rapid growth of e-business in the last years made sponsored search a multi-billion dollar industry, which will continue to grow in the upcoming years. Approximately 50% of the total online advertising spending today is used for sponsored search, where search engine providers use sponsored search auctions for pricing the clicks and ranking the ads based on the bids advertisers submit for a s...

In sponsored search auctions advertisers typically pay a fixed amount per click that their advertisements receive. In particular, the advertiser and the publisher enter into a contract (e.g., the publisher displays the ad; the advertiser pays the publisher 10 cents per click), and each party’s subjective value for such a contract depends on their estimated click-through rates (CTR) for the ad. ...

P auctions are sometimes plagued with a chosen supplier’s failing to accomplish a project successfully. The risk of project failure is considerable, especially when the buyer has inadequate information about suppliers ex ante and the project can only be evaluated at the end. To manage such uncertainty, a model of competitive procurement and contracting for a project is presented in this paper. ...

We present a very brief history of the origins of sponsored search, which is the presentation of text advertisements in response to a user’s search query.

Sponsored search has gained considerable attention in Web searchrelated studies. In this paper, we investigate into the user interaction process on search engine result pages (SERPs) considering the influence of sponsored search results. We integrate different styles of sponsored links into SERPs to systematically study how they affect users’ behavioral preferences. Based on an analysis into us...

S search is the mechanism whereby advertisers pay a fee to Internet search engines to be displayed alongside organic (nonsponsored) web search results. Based on prior literature, we draw an analogy between these markets and financial markets. We use the analogy as well as the key differences to present a theoretical framework consisting of a set of research questions about the pricing of keywor...

In the standard model of sponsored search auctions, an ad is ranked according to the product of its bid and its estimated click-through rate (known as the quality score), where the estimates are taken as exact. This paper re-examines the form of the efficient ranking rule when uncertainty in click-through rates is taken into account. We provide a sufficient condition under which applying an exp...
