Sentiment trend tracking on autopilot:
know the mood shifted before the rating average does
A star rating average moves slowly. Sentiment underneath it can shift fast, a new batch complaining about the same issue weeks before the overall number budges. We build a model that scores sentiment on every review as it comes in and alerts when the trend turns, not when the average finally catches up.
Why the star average lags behind reality
A star rating average is a lagging indicator by design. It blends every review ever left. A fresh batch of complaints about a shipping delay or a quality change takes a long time to move a number built on months of history. By the time the average visibly drops, the problem has usually been live for weeks. It already affected every customer who bought in that window, not just the ones who left a review.
Reading reviews manually for early warning does not scale past a small volume. A team checking reviews once a week, scanning for anything that feels off, relies on attention alone. That misses the kind of gradual drift that is easy to overlook day to day, obvious only in hindsight, once it has already become a real reputation problem.
The deeper issue is that sentiment is rarely broken down by topic in a casual read. A reviewer who loves the product but hates the delivery time gets read as a fine 4-star review. The delivery complaint buried inside it might be the fifth one that week on the same issue.
What the model tracks
The model scores sentiment on every review as it comes in, across whichever platforms you sell or list on: Google, marketplaces, app stores, your own site. It tags each review to a specific topic: shipping, product quality, customer service, pricing. That replaces one blended score per review with scores that actually mean something. A review that praises the product but complains about delivery gets scored on both topics separately, so a shipping problem never hides behind an otherwise positive review.
The dashboard shows sentiment as a trend over time, by week. You can split it by product, location or channel, to see the direction and speed of a shift, not just a static lifetime average.
When sentiment on a topic turns negative and stays that way, not just a single bad week, an alert fires. It names the topic and the products or locations it is concentrated in. That gives your team time to investigate and respond before the issue drags the overall rating down.
Before go-live, the model runs against a past period you already know involved a real reputation issue. That shows whether it would have caught the shift early enough to matter.
What your team decides
Deciding what to do about a flagged trend, a supplier call about quality, a shipping policy change, a public reply, stays with your team. The model surfaces where sentiment is shifting and what it is about. It does not draft public responses or make operational changes on its own.
Guards on accuracy
Every sentiment score and topic tag is logged, so a team reviewing a trend can see the actual reviews behind it, not just a number. Before go-live, we check the model’s topic tagging against a sample of human-read reviews. That confirms it matches how your team would categorise the same feedback. A kill switch pauses alerting in one message if something looks miscalibrated.

Pair this with review and reputation replies so a flagged negative trend feeds directly into a faster response workflow. Social listening dashboards apply the same sentiment tracking to social mentions rather than reviews. For periodic deep-dive analysis, see review mining for insights.

FAQ
How much does sentiment trend tracking cost?
From $800 for tracking across your main review platforms, live in 7 to 12 days. A department package combining this with review reply automation usually starts at $2,500.
How is this different from review mining for insights?
Review mining extracts themes from a batch of reviews for a one-off or periodic report. This automation runs continuously. It is built to alert the moment sentiment on a topic starts trending down, so you find out during the shift, not after a quarterly read.
Which platforms can it watch?
Google reviews, marketplace reviews such as Amazon, Shopee or Lazada, app store reviews, and on-site reviews. Which ones we connect depends on what each platform exposes through an API or export.
Can it tell us what specifically is driving a negative trend?
Yes. Topic tagging attaches each review's sentiment to a specific area: shipping, product quality, customer service, pricing. That means an alert names the actual issue rather than just saying sentiment dropped.
What happens with sarcasm or mixed reviews?
The model is tuned on review language specifically. Mixed sentiment, praise for the product, complaint about shipping, gets scored on each topic separately within the same review, instead of one blended score.
