What a claim record is How to read this page

One statement, bounded on purpose

The headline is a single claim that a named source supports. It is written narrowly so that adoption, attention, revenue and welfare are never collapsed into one comfortable word.

The three sections below the fold

What this does not establish is the boundary of the evidence. Counterevidence & uncertainty is what argues the other way. What would change the reading is the observation that would move it. A record missing any of the three is incomplete, not merely brief.

Primary routes are checkable

Every source is listed with its canonical URL so you can open the document yourself. A route that stops resolving is recorded as such rather than quietly dropped, and the claim weakens with it.

MWITA-MIO-2026-004 · Evidence A · P1

eBay randomized paid-search suppression and found no measurable short-run benefit from brand-keyword ads; for nonbrand terms, the total paid-search regime added an estimated 0.66% to sales with a 95% confidence interval spanning -0.42% to 1.74%, and average returns were negative because frequent users absorbed most spend without responding.

What this does not establish

Does not establish that paid search is ineffective for less familiar brands, competitive brand auctions, new customers, or different query portfolios.

Counterevidence & uncertainty

Experimental returns were a fraction of conventional nonexperimental estimates, while heterogeneity shows that a single campaign-average effect hides responsive acquisition segments.

What would change the reading

Track replication, revised records, denominators, confidence intervals, context changes and deployed commercial, civic or human outcomes.
