Li, K., Chen, Y., & Zhang, L. (2020). Journal of Retailing and Consumer Services, 55, 102107.
Plain-English take
Looking across the studies, product-category moderation. For your marketing: This is a second synthesis supporting a context-dependent view of reviews.
How much weight to give this
3.5/5 Useful evidence with meaningful caveats
The 1–5 evidence-check score is a practical reading aid, not a formal peer review or a probability that a conclusion is true. It combines design strength (2 points), sample reporting (1), comparison/control clarity (1), and how much of the paper could be checked (1). Access affects how confidently this directory can assess a study, not the study's underlying quality. Blinding is reported separately because it is not relevant to every design.
A synthesis can show patterns across studies; its strength depends on the included evidence.
A usable sample size is not stated in the profile's accessible source.
No single control group; check inclusion criteria, study quality, and variation across settings.
This profile could be checked against an abstract or metadata, not the full paper.
Double-blind? Not applicable in the same way as a participant-treatment experiment.
Research question
What the authors investigated
Which online-review features relate to product sales, and does product category moderate those relationships?
Design
Meta-analysis of 28 studies on online reviews and sales.
Sample and setting
Prior empirical studies across online product-review settings; the abstract does not report a pooled observation count.
Reported result
What the study found
The analysis found product-category moderation. Review length and special shipping were the factors reported as not significantly affecting sales; other analyzed review-related factors showed significant relationships.
This is a paraphrase of the source. Check the original paper for definitions, estimates, statistical uncertainty and analysis details.
Scope and transfer
Limitations to keep in view
The authors note that database choice and search terms may have omitted relevant studies, and the synthesis depends on the quality and reporting of included literature.
Possible founder application
A second synthesis supporting a context-dependent view of reviews. Check whether your SaaS category and buyer risk resemble the products represented before applying an effect.
