Meta-analysis has become increasingly popular in marketing to quantitatively integrate research findings across many studies. In the euphoria of meta-analyses, meta-analysts may inadvertently include studies published in predatory journals, and these studies will be integrated in effect size estimates and influence findings, recommendations, and, eventually, marketing theory and practice. The purpose of this paper is to raise awareness among marketing meta-analysts regarding predatory journals. It provides evidence that nine meta-analyses (six of which were published in 2021 and 2022) comprised studies from articles published in three predatory marketing journals. The fundamental contribution of this study, however, is to provide guidelines for meta-analysts regarding studies published in predatory journals.
