# 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.

## FAQ

### 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.
