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.

What this does not establish

The treatment is cheaper mobile access after a regulation, not a review-management intervention; Rome tourism exposure, navigation complementarity and rating strata prevent direct transfer to ordinary local SMBs or Maps optimization.

Counterevidence & uncertainty

Information access rewards strong reputations and disciplines weak ones: lower-rated firms do not gain sales and face doubled exit, while surviving low-rated firms upgrade labor and later ratings.

What would change the reading

Track replication, revised records, denominators, confidence intervals, channel changes and realized behavioral or commercial outcomes.
