The 26× variation spread
A mass-market line launched on non-exclusive terms, competing with grey-market sellers for its own Buy Box. Variation-level analysis found where the margin actually was.
VELOCITY SPREAD IN ONE FAMILY
26×
THE SITUATION
A volume Brazilian haircare line launched into Canada on non-exclusive terms, competing against grey-market sellers for the Buy Box on its own listings.
WHAT IT WAS COSTING
Parent-level reporting averages children into a single number that describes none of them. Budget spreads evenly across a family where one child is doing nearly all the work, so the weak children buy clicks they cannot convert while the strong one gets less than it earned. The report looks healthy the entire time.
WHAT WE DID
We measured velocity at the child. Inside one five-variation family the spread between best and worst was 26×, on the same listing page, the same traffic and the same price band. We isolated the strongest child into a dedicated manual campaign with its own bids, budget and negatives, then applied top-of-search modifiers to hold the position where category intent concentrates.

TAKEAWAY
Same listing, same traffic, same price band, and a 26× difference in what the children were doing. Variation-level management is not a refinement, it is where the margin lives. And a line without exclusivity can still hold two thirds of its own Buy Box while winning top-of-search.
