Definition
Bazaarvoice is a software and network business that provides the ratings-and-reviews module on the product pages of a large share of US retail — Walmart, Target, Home Depot, and hundreds of others across grocery, hardline, softline, and specialty categories. It also runs a syndication layer: a review collected in one place (a retailer site, a brand's own site, or a sampling campaign) can be distributed to every other participating retailer that lists the same product, matched by UPC or manufacturer part number.
For consumer brands, Bazaarvoice is both a review-collection channel and a distribution channel. For analysts, it is a data source that needs explicit deduplication, because the same review can legitimately appear on several retailer pages. Each review carries a persistent Bazaarvoice review ID, which is the correct primary key for deduplication — not the retailer page URL or the on-page review timestamp, which differ across surfaces even for the same underlying record.
Why it matters
Three implications matter for anyone analyzing product feedback. First, review volume at the retailer level is partly a syndication artifact — a new SKU can appear at launch with 50 reviews carried over from a prior generation or from the brand's own site. Second, attribution is tricky: a negative review seen on Target might have been written by a Walmart shopper. Third, moderation is unified — Bazaarvoice applies one policy across participating surfaces, which means a brand that objects to a review must work through one moderation process, not dozens.
Treat Bazaarvoice as one channel with multiple display surfaces, not as multiple independent review streams. Analytics that skip deduplication will overstate volume, understate the significance of native reviews on any one retailer, and make it hard to isolate the retailer-specific experience (shipping, in-store pickup, returns) from the product-level experience that travels with the review across surfaces.
Example
A home-appliance brand launches a cordless vacuum at Walmart, Target, and Home Depot. Three weeks in, the Walmart Item ID page shows 340 reviews, the Target TCIN shows 310, and the Home Depot OMSID shows 295. Without deduplication the brand reports "945 reviews analyzed." In reality roughly 80% of the corpus is shared — the same 270 reviews syndicated across all three, plus 70 Walmart-native, 40 Target-native, and 25 Home Depot-native writes.
A brand that aggregates by Bazaarvoice review ID sees the true volume (405), dedupes correctly, and spots the one theme — "battery indicator misreads at 20%" — that appears 38 times across channels, linked to one UPC. It also spots the retailer-specific signal that syndication hides: Home Depot-native reviews cite in-aisle availability issues, which are a Home Depot operations problem, not a product one.
