We have most likely all had this thought once: how does this website know these things about me? Well, basically every website collects information on its users. However, users are not always aware because not every website informs its user on this data collection process.
Personalization is concerned with delivering the right content to the right person at the right time, which makes it a customer oriented marketing strategy. Data is needed to be able to provide this content delivery to the right person. When websites make a conscious effort to inform users on data collection, they engage in overt information collection (Sundarand Marathe 2010). It is assumed that users atomically agree on data collection after they have received such an information effort. However, when users experience ads that contain personal information without being informed that their data is collected by the website, this will lead to negative reactions and can harm businesses (Milne, Bahl and Rohm, 2008). This sense of vulnerability is more like to be accepted by users when the website is marked by trust (Urban, Amyx, and Lorenzon 2009).
The result is a personalization paradox , where personalization effectiveness depends on the context. It would be beneficial for online retailers to understand how they can prevent or minimize the negative effects of personalization. Practitioners claim it is more user friendly to not inform users because informing them would result in users to take longer in performing online tasks. Moreover, when users do not know their data is collected, they might act more naturally and thereby delivering richer data (Verhoef et al. 2010). For the customers themselves it is important that they feel conformable during website visits. Therefore, retailers need to make sure customers feel safe, while still being able to provide them with optimal personalization marketing to enhance customer experience.
The research includes three studie. Study 1 and 3 had the most interesting findings. In the first study, the personalization paradox is tested by comparing situations in which websites did and did not inform users on data collection, and how more personalized advertisements affected click-through rates. Facebook is used as the setting of the research because promotions through social media are important. Participants first had to review the advertisement. Hereafter, they could fill in their click-through intention and their perceived vulnerability on a 5-item scale. The results suggest that click-through rates after personalized advertisements increase when websites overtly collect data and decrease when websites covertly collect data due to the vulnerability it causes to users, meaning that vulnerability mediates the effect of personalization and information collection on click-through intentions ( see Figure 1). In the third study, the findings suggest that negative effects caused by collecting data covertly, can be mitigated by providing information and control to users at the moment that personalized advertisements are shown to them. Probably because this enhances reliability and trustworthiness.

The paper convincingly addresses the personalization paradox and provides valuable ways in which negative effects of covertly data collection can be mitigated. The result is that retailers can make careful decisions as to what information should be used and how sensitive this information is to users. Furthermore, retailers need to be transparent on their data collection methods, which will benefit their business. Lastly, this will probably enhance customer satisfaction, since customers will feel like retailers act in the best interest of the customer.
