Review velocity: why fresh reviews outperform old ones
A five-year-old five-star review is worth far less than a five-star review from last week. Reviews are perishable: and velocity, not just volume, is what keeps them working.
Brands count reviews, "we have 4,000 reviews", as if the number were the asset. It is half the asset. The other half is when those reviews were written, because a review ages, and shoppers know it.
A review is a perishable asset
A shopper reading reviews checks the dates. A product with hundreds of reviews, none from the last year, raises a quiet doubt: has the product changed, has quality slipped, has everyone moved on? An old review does not just count for less, a wall of old reviews actively signals a stalled brand.
Why velocity matters
- Recency reassures, recent reviews say the product is current and the brand is active.
- Relevance, a recent review reflects the product as it is now, not a past version.
- Discovery, review platforms and search tend to favour fresh review activity.
- Momentum, a steady stream reads as a product people are buying right now.
Keeping velocity up
- 1Make review collection a continuous, automated post-purchase habit, not an occasional campaign.
- 2Ask every customer, at the right moment, with no friction.
- 3Surface recent reviews prominently, so the page always shows current proof.
- 4Track velocity, reviews per week, as a metric, alongside the total count.

PDP before and after UGC: what actually changes on the page
Strip a product page back to brand-only content, then layer verified customer photos, video and reviews into the middle scroll, and watch what moves. A scroll-by-scroll look at the before and after, the numbers the public studies actually support, and where "just add UGC" gets oversold.

How to vet a creator: audience authenticity, engagement, and the fake-follower problem
On a typical account, roughly a fifth of followers are fake or inactive. Here is how to read the signals that separate a real audience from an inflated one, before you pay, with the four checks that catch most of it.
