Participant comparison studio

Compare firms, products, services, and aggregate categories within the same published market definition. These observations do not establish a firm-wide share.

Published participant rows inside one selected market definition and a year reported for every selected series.

Never inferred here

Compare source-labeled shares only inside the selected market definition and a shared reported year. Selected rows are never added into a firm-wide total, and labels do not establish legal identity, ownership, control, conduct, or market power.

Selection console

Choose one market, then two to four labels.

Changing the market replaces the eligible participant set. Every selected series must share the displayed reporting year.

Missing years remain blank. Each line uses exact source rows and keeps the selected market definition fixed.

Shared year

The upper field preserves the market denominator. The lower field changes the question to movement, not share level, and never fills missing years.

Largest selected decline: Google Search
Common evidence window: 2023-2026

Definition and evidence contract

Keep the denominator attached to every result.
