BDO USA: mirrors Crowe — /industries/<slug>/ pattern with separate /services/ namespace

Claim: BDO USA mirrors the Crowe IA pattern: /industries/<slug>/ for industries, separate /services/ namespace for services. Same orthogonal-axis logic.

Source: https://www.bdo.com/industries (field research, May 2026).

Confidence: Verified.

The data point: When two independent large professional services firms (Crowe + BDO USA) converge on the same URL convention, that's an industry-level signal. Treat /industries/<slug>/ as the default Pattern A for new multi-vertical service business sites. See Reference: 5 URL structure patterns for multi-vertical IA (A through E), with field-observed usage.
