Review Velocity
Quick answer
Review velocity is the rate at which new reviews come in for a brand over a given period, as distinct from the total review count or the average rating. A sudden change in that rate, rather than in the rating itself, is often the more useful early signal that something is going on.
Why it matters
A rating can stay steady even while something notable is happening underneath it. If a brand suddenly gets far more reviews than usual, after a launch, a migration, a pricing change, or far fewer, after a product goes quiet or support slows down, that shift in velocity often shows up before any change in the rating does, and tells a different part of the story than the rating number alone, one about how many customers were moved to speak up at all.
How to measure it
Track review count per period, weekly or monthly, per platform, compare it against a brand's own recent baseline rather than an absolute number, and check whether a spike or drop in velocity lines up with a specific event, a launch, an outage, a pricing change, so the shift can be explained rather than just noticed and left unexplained. A baseline built from several prior periods is more useful than comparing against any single earlier period alone.
Example
A brand's average rating barely moves one month, but its review velocity on one platform roughly doubles following a rocky product migration. Most of the new reviews are neutral to mildly negative, pulling the rolling average down only slightly even though a much larger number of customers were moved enough to leave feedback at all, a shift the plain rating number alone would have made easy to miss. The team only caught the spike because they were watching review count alongside the average score.
Frequently asked questions
Is review velocity the same as review volume?
Related but not identical. Velocity is about the rate of new reviews over a period, while volume usually refers to the total count a brand has accumulated so far.
Why would a drop in review velocity matter?
A sudden drop can mean fewer customers overall, fewer customers motivated enough to leave feedback, or a platform change making it harder to leave a review, and each of those needs a different response.
Should review velocity be tracked per platform or combined across all platforms?
Per platform first. A spike on one site tied to a specific event is easier to explain than a combined number that blends several unrelated platforms together.
Does a spike in review velocity always mean something went wrong?
No. A successful launch or a well-received new feature can also cause a spike. The sentiment of the new reviews, not the spike in count by itself, is what tells a team whether to worry.
