How RateBud Detects Fake Reviews
Our AI combines six detection signals to catch manipulation that humans and basic tools miss.
Timing Pattern Detection
Identifies suspicious review bursts — when dozens of reviews appear in a short window, it usually means a paid campaign.
AI Text Detection
Scans review language for AI-generated patterns, template phrases, and unnatural sentence structures common in mass-produced fake reviews.
Reviewer Behavior
Analyzes review history patterns to flag accounts that only post 5-star reviews or exhibit bot-like behavior.
Verified Purchase Audit
Checks the ratio of verified vs. unverified purchases. Low verified rates signal potential manipulation.
Rating Distribution
Detects unnatural rating patterns — legitimate products have a natural distribution, while manipulated ones cluster at 5 stars.
Keyword Sentiment
Analyzes what reviewers actually say about the product and flags suspicious over-enthusiasm or generic praise.
