Abstract: Online advertising has become a significant source of revenue for publishers and search engines. One important business model in online advertising is the so-called non-guaranteed delivery (NGD) system, in which advertisers purchase their targeted advertisement (abbreviated ad) inventories like page views or link clicks on the spot market through an auction mechanism. Despite the success of the NGD system, it has several limitations including the uncertainty in the buyer's payment, the volatility in the seller's revenue, and the weak loyalty between buyer and seller. To alleviate these problems, guaranteed delivery (GD) systems have been recently studied in which advertisers are able to secure their targeted future deliveries through standardized or customized contracts. I will talk about several GD systems that we have developed from seller's perspective. The first GD system is an optimal dynamic model that unifies programmatic guarantee and real-time bidding in display advertising. This study solves the problem of algorithmic pricing and allocation of guaranteed contracts. Secondly, we study a multi-keyword multi-click ad option. This work proposes a flexible way of guaranteed deliveries in the sponsored search context. Thirdly, we propose a lattice framework for pricing an ad option with the stochastic volatility underlying model. Fourthly, we discuss an average price ad option for the case when underlying spot market prices are discontinuous.
