MWITA-SBO-2026-007 · Evidence A · P1
Randomized access to eBay's Seller Hub analytics increased weekly seller revenue by 3.6% on an intention-to-treat basis.
What this does not establish
The 12.5% estimate is a local complier effect, not an all-user lift; the 2016 B2C marketplace rollout is not a complex B2B opportunity process.
Counterevidence & uncertainty
The tool did not significantly raise prices, and most invited sellers did not adopt it.
What would change the reading
Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial or human outcomes.
