Recommendation marketing through acquaintances has received significant attention in both academia and practice for years. A relatively young area of research in this context is Electronic Word-of-Mouth (EWOM), which refers to the electronic form of word-of-mouth communication. Previous studies have shown that credibility is a crucial factor in the adoption of EWOM. This filter is particularly important for online information because it is often unclear who the source of the information is. While consumers are generally more inclined to trust individuals rather than companies, the information provided is usually not verifiable. This study addresses this issue and provides an overview of the factors considered by recipients when assessing the credibility of EWOM messages.
