This thesis is about the Online review trust factors and the characteristics and person-specific reputation. Especially abou the question, "Which factors make online reviews trustworthy?"
Online reviews are more and more used by consumers trying to make an informed decision whether to buy a product or service. Trust plays a central moderating role in this decision-making process. However, specific factors that lead to the emergence of trust have not been identified and subsumed among scholars.
This thesis aims to fill this gap by addressing empirically proven conceptualizations of trust factors and evaluating them within an online setting and demonstrating these factors by descriptive visual aids. The results show that consumers essentially use review characteristics and person-specific factors to assess trustworthiness. The review length, its writing style, real pictures, and the review’s extremity primarily influence trustworthiness. The number of submissions of a reviewer, certain review patterns, virtual badges, real profile pictures, and real names with contact information secondarily influence trustworthiness. If a review is perceived as untrustworthy, it gets discounted by consumers.

Objectives and Core Topics
This thesis examines the factors that influence the perceived trustworthiness of online consumer reviews. It aims to identify specific characteristics—both inherent to the review content and associated with the reviewer—that enable consumers to distinguish between authentic feedback and potentially fraudulent or manipulative content in a digital marketplace.
- Mechanisms of trust and reputation in online environments.
- Impact of review content attributes such as length, writing style, visual aids, and sentiment extremity.
- Significance of reviewer-specific signals, including submission history, activity patterns, and social proof markers like virtual badges or profile identifiers.
- Strategies for consumers to improve their decision-making process when faced with information overload.
- Guidelines for online platforms to foster a more transparent and trustworthy review culture.
Excerpt from the Book
3.2.1. Review Length
The length of a review is one of the first characteristics a potential customer notices and one of the easiest factors to assess with minimal mental effort (Filieri, 2016). Longer reviews can transfer more information such as product details and use case in specific contexts (see figure 1). Longer reviews can be considered more helpful and trustworthy than shorter ones (Mudambi & Schuff, 2010). This is especially true for new reviewers who have yet to establish a proper reputation within their communities (C. H. Peng et al., 2014). However, the generalized heuristic that longer reviews are always better and should, therefore, in any case be favored is potentially misleading since there is evidence that on some sites the length of the review is considered neither helpful nor unhelpful (Korfiatis et al., 2011). The quality and detail of information within those lengthy reviews ultimately lead to the emergence of solid trust (Filieri, 2016). Moreover, the presented information must be concise and logical, related to real product experience and specific product characteristics, and written as objectively as possible, as will be discussed in 3.2.4. Fake reviews can easily be identified from real ones by applying a simple heuristic such as looking for subjective comments or overly excited superlatives, emotional language or sensational titles for example “the best,” “better than everyone,” “amazing product,” or “good” without any further references (see figure 2; Filieri, 2016). These examples provide no clues that their writers experienced the product or services and may immediately be disregarded as fake and overly biased (Anderson, 1998). Vailidity can often be evaluated by glancing at the length of the review because shorter reviews naturally provide less information than longer reviews (Mudambi & Schuff, 2010).

Frequently Asked Questions
What is the core focus of this thesis?
The thesis investigates which specific factors influence the trustworthiness of online consumer reviews, helping readers navigate information overload and identify potentially manipulative content.
What are the primary thematic fields addressed?
The work spans business, psychology, and communication, specifically focusing on reputation management, consumer decision-making processes, and the digital manifestation of trust.
What is the primary research goal?
The objective is to provide a comprehensive, academically backed overview of the characteristics that make online reviews seem trustworthy or untrustworthy to potential buyers.
Which scientific methodology is utilized?
The author performs a traditional, comprehensive literature review, synthesizing insights from a vast range of peer-reviewed academic papers and studies.
What does the main body of the work cover?
It covers two major categories: formal review characteristics—such as length, writing style, and the use of images—and person-specific reputation factors, such as reviewer history and identity disclosure.
Which keywords best characterize this research?
Key terms include online reviews, trust factors, online reputation, consumer behavior, reviewer credibility, and digital decision making.
Why is review extremity considered a complex factor?
Unlike simple markers like review length, assessing review extremity requires more cognitive effort, as extreme positive or negative sentiment often signals bias or lack of genuine experience.
Does the thesis conclude that using real names increases trust?
Surprisingly, no. The research indicates that profiles using real names do not necessarily appear more trustworthy, and in some contexts, such disclosure can even negatively affect perceived credibility.
What role do virtual badges play for reviewers?
Virtual badges act as symbols of expertise and past success, helping consumers quickly identify more credible reviewers who have demonstrated consistent, meaningful participation in the community.
