Reviews help shoppers evaluate products, but the collection process shapes what those reviews can prove. This guide separates customer opinion from rating summaries, incentives, moderation, and endorsements. Ask for feedback consistently, keep provenance clear, and treat automated sentiment as a sorting aid rather than ground truth.

📎 How to read this page
What it means gives the precise meaning. Operator translation gives the version you might hear in a real ecommerce meeting. In real life shows an illustrative example. Watch out and the confusion boxes show where a familiar term can mislead.
📈 Read the relationships first
These combinations are diagnostic hypotheses, not proof of causality. Compare the same period and scope, then investigate the mechanism.
Review gating + unusually high average rating
Usually means: Can suggest selection bias rather than unusually happy customers. Check next: invitation routing and review distribution.
Incentive + review request
Usually means: Can affect perceived independence. Check next: disclosure, platform rules, and whether the benefit depends on positive sentiment.
Review syndication + product variants
Usually means: Can broaden useful evidence across channels. Check next: that the review belongs to the same product and variant.
New product version + older reviews
Usually means: Can make historical feedback less representative. Check next: dates and meaningful product changes.

🔀 Star rating vs product review
A star average compresses scores; a written review provides an individual account. Neither alone represents every customer.
🔀 Verified purchase vs unbiased review
A purchase badge identifies what the platform verified. It does not prove the opinion is independent or typical.
🔀 Review moderation vs review suppression
Moderation applies transparent content rules. Removing criticism solely because it is negative distorts the evidence.
🔀 Review vs testimonial
A testimonial is presented as an endorsement; context, material connections, and implied claims may require attention.
