Review monitoring is in development.
Ratings and review counts need a connected market data source, and that isn't live yet — so they aren't recorded and review alerts can't be sent today. This page explains how the feature works, and every panel is a sample.
Two jobs
Monitor the change. Analyze the reason.
Review Monitoring answers one question: what changed in customer feedback around this product? Review Analyzer helps you look into why.
Review Monitoring
Tracks the numbers over time.
- Average rating
- Review count
- Review growth
- Significant changes
- Alerts
Review Analyzer
Looks at available review text to find:
- Positive themes
- Complaints
- Feature requests
- Overall sentiment
- Product-improvement ideas
It only works with review text that's actually available or that you provide — it doesn't have access to every Amazon review.
Explore Review AnalyzerA small rating change can be worth investigating.
Shoppers see the average rating before they read a word. Knowing when it moves — and how fast reviews are arriving — gives you a reason to look closer.
- Average rating changes can affect how shoppers see a product.
- Review growth adds context about market activity.
- Sudden changes can be worth investigating.
- Competitor review growth can show shifting activity in a category.
- Review growth isn't sales, and a rating drop doesn't prove a quality problem on its own.
Workspace
Keep review signals across your catalog in one view.
Once monitoring is live, each product will show its current and previous rating, review count, 30-day change and when it was last observed.

See rating and review-count movement over time.
History shows whether a change is sudden or gradual. Markers such as a listing update or price change help you review surrounding events — they don't show what caused a change.
Review growth, not sales
AmzEngine calculates how many reviews were added over an observed period. That's review growth — not a sales figure.

Alert types
Choose which review changes deserve an alert.
Alerts are based on the rating and review count. Competitor rating alerts and alerts for individual new reviews aren't offered — they'd need a data source that supports them reliably.
- Rating drop
- The average rating falls by at least an amount you set, such as 0.2.
- Rating threshold
- The average rating falls below a level you set, such as 4.2.
- Review count change
- The review count grows by more than a number you set.
- Review growth change
- Review growth changes by more than your rule allows.
Not yet available: review alerts start once ratings and review counts are being recorded.

Investigate
When the number changes, investigate the feedback.
A changed rating tells you to look. The reviews themselves tell you what customers are saying.
- Rating drop
- Open Review Analyzer
- Available review text
- Positive themes
- Complaints
- Feature requests
- Possible improvements
AI only analyzes review text that's actually available or that you provide. It never invents customer quotes or themes.
Not yet available: analysis of real Amazon review text, sentiment breakdowns and complaint trends aren't live yet.
Turn recurring feedback into listing and product improvements.
If customers keep raising the same question, your listing may be able to answer it better. Reviewing listing content is one possible step — it isn't proof of why a rating changed.

Compare ratings with competitors.
Seeing a competitor's rating and review growth next to yours helps you judge whether a change is about your product or the whole category.

Understand what a review observation means.
Each figure is what the data source reported at one moment. Amazon rounds and updates ratings on its own schedule, so small differences between sources are normal.

FAQ
Review monitoring questions
What is Amazon review monitoring?
Recording a product's average rating and review count over time, so you can see when they change and how quickly reviews are being added.
What's the difference between Review Monitoring and Review Analyzer?
Review Monitoring watches the numbers — rating and review count. Review Analyzer looks at review text to find themes. Monitoring tells you something changed; analysis helps you look into why.
Is review monitoring available now?
Not yet. Ratings and review counts need a connected market data source, which isn't live, so AmzEngine can't record them for customers today. This page explains how the feature works.
How often are ratings checked?
No checks run yet, so no frequency applies. AmzEngine won't promise real-time checking; when checks start, each figure will show when it was observed.
Does AmzEngine alert me to every new review?
No. Monitoring is based on the rating and review count, not individual reviews. Alerts for individual new reviews would only be offered if a data source supported them reliably.
Does a rating drop mean my product has a quality problem?
Not necessarily. A rating change is a reason to look closer, not proof of a cause. Reading the reviews themselves is usually the next step.
Does review growth tell me a product's sales?
No. Review growth is useful context, but many buyers never leave a review, so it can't be turned into exact sales.
Can I monitor competitors' ratings?
Competitor rating tracking will depend on the same market data source and isn't available yet.
Does AmzEngine read all Amazon reviews for a product?
No. Review analysis only works on review text that's actually available to AmzEngine or that you provide, and it never invents quotes or themes.
Which channels can review alerts use?
When review alerts launch they'll use AmzEngine's existing notification system: in-app and email as standard, with SMS, WhatsApp and Telegram where enabled.
How do you avoid noisy alerts?
Alerts only fire when a threshold you set is crossed, with cooldowns and duplicate suppression, so a tiny change like 4.50 to 4.49 doesn't trigger an alert on its own.
AmzEngine is an independent software provider and is not affiliated with or endorsed by Amazon.
