User settings for advertising optimization on Facebook: Active customer participation or settings blindness?

Facebook and many other social media companies act on information markets with various player groups, which are differentiated by the kind of payment, one group paying with money (normally, advertisers) and the other group paying with their personal data or their attention (i.e., Facebook’s users being simultaneously the advertisers’ potential customers). In order to minimize users’ problems with (rather annoying) ads on digital services, some providers offer user settings for the optimization of advertising. We analyzed the information behavior of Facebook users concerning ad settings with the help of an online survey (N = 1,021). Only about 40% of participating Facebook users know about personalization of settings of their advertising preferences. More than 20% of the users who work with Facebook’s advertising optimization are satisfied since the changes, but 35% are unsatisfied, and another 32% have a generally negative attitude towards online advertising. To describe customers’ disregard or ignorance of settings we introduce the term “settings blindness.” Especially the users’ gender and their educational background influence the information behavior concerning advertisement settings. The results have practical implications for Facebook users (namely, setting their own preferences for ads and thus seeing only personally customized ads), for Facebook and other social media companies (producing less annoying ads leading to a better customer loyalty and maybe more trust in the service), and for advertisers on social media (improving the correct addressing of the target groups).

How online review environment affects review generation behavior: A competing for attention perspective

From the perspective of competing for attention, this study attempts to examine how a potential reviewer’s review content in terms of topic diversity and topic popularity is affected by the review environment, which is characterized by review volume, review variance, and time distance. The empirical analysis is based on 70,383 restaurant reviews collected from Yelp. The Latent Dirichlet Allocation (LDA) model is adopted to conduct review text mining. Our empirical findings indicate that reviewers are more likely to evaluate the product on a wider range of topics when exposed to a larger volume or lower variance of existing reviews. Our findings also show that reviewers prefer to talk about popular topics as the volume of prior reviews increases or when prior reviews exhibit higher variance, but they tend to discuss unpopular topics when time distance from the first review increases.     

Bracketing or reinforcing? Socio-economic status,network power,and online deliberation

The extent to which the deliberative scenario brackets socio-economic inequalities (i.e., functioning as an ideal public sphere) has been long-debating. This study empirically addresses this question in the online setting. We test whether offline advantages (i.e., economic and cultural capitals) can be translated into power in online deliberation and how their dynamic relations further influence interlocutors’ deliberation experience (i.e., perceived procedural fairness and validity claim). Power is conceptualized as network power, including prestige (indegree), leadership (outdegree), and brokering power (betweenness). A national sample of Singaporeans participated in a three-week online deliberation, and network power is measured based on the web log. The participants answered a two-wave (i.e., pre- and post-deliberation) survey to indicate individual attributes. Structural equation modeling finds that online deliberation brackets as well as reinforces offline status. Economic capital is suppressed while cultural capital translates into network power, which further influences interlocutors’ evaluation of the deliberation.
