GEO/AIO query-level observations: BMW, Mercedes-Benz and Audi across three generative platforms, August 2026

Methodologically, the research adopts an exploratory multiple case study design of three directly competing premium automotive brands, BMW, Mercedes-Benz and Audi, examined through their international flagship websites (bmw.com, mercedes-benz.com, audi.com) across three complementary dimensions: a comparative SEO audit, a systematic GEO visibility assessment on three leading AI platforms using a scientifically grounded eighteen-query framework, and a seven-criterion GEO-readiness content and structure analysis, supported by within-case and cross-case synthesis and framework development.

The findings show that off-site brand authority signals (such as branded web mentions and external media coverage) remain the primary drivers of visibility in AI-generated results, while on-site GEO-readiness (conversational content, schema, E-E-A-T) functions as a necessary but insufficient condition, creating a “GEO-readiness paradox” in which Audi’s superior content architecture does not translate into superior AI visibility.

On this basis, the dissertation proposes a dual-layer marketing framework that distinguishes an authority foundation, built through public relations and brand equity investments, from a citability infrastructure, built through AI-oriented content and structural optimization, and derives brand-specific strategic roadmaps that illustrate how marketers can orchestrate SEO, GEO and AIO as an integrated system to sustain brand salience and preference in AI-mediated customer journeys.</p>
