Online retargeting based on consumer behavior: a comparison between models Master thesis Menno Nelis Student no: 5929040 Supervisor: Prof. Dr. Dick Heinhuis University of Amsterdam Amsterdam, The Netherlands Faculty of Science Information Studies Track: Business Information Systems August 2017 Abstract Behavioral retargeting is a widely used technique within the field of online marketing to generate sales out of customers that already visited your website. These campaigns are based on the online behavior and interests of the customer. Although there is a huge growing market for behavioral retargeting, current online campaigns do not yet use models of consumer behavior or decision making as input for their campaign design. Behavioral retargeting is seen as a trick by marketers and their campaigns are optimized empirically. This research selected three models of consumer behavior or decision making; the Howard-Sheth model, the EBM model and the Bettman model. The phases of these models were translated from offline to online behavior and used to create three different retargeting campaigns. The fourth campaign is the control group, which is not based on a model. A Dutch travel company, Corendon, provided a platform to run the different experiments. Their visiting customers on the website were used in the experiment to sub divide customers among the different experimental campaigns, based on the selected models. The results obtained from these experiments were measured in six online metrics: the bounce rate, click through rate, conversion rate, cost per action, cost per click and the return on investment. After the campaigns ran for a week, results showed that the campaigns based on a consumer behavior or decision making model all scored better than the control group. Comparing the experiments on the different metrics, it can be concluded that a retargeting campaign based on the Bettman model scores highest on five of the six metrics. Therefore the Bettman model is identified as the most suitable model for the design of an online retargeting campaign, out of the three models used during this study. This research shows that marketers should not neglect models of consumer behavior or decision making, but should embrace and implement them to improve their behavioral retargeting campaigns.
