MediaReach
Building Brand Authority in AI-Search Answers
Toshiki Matsumura, CEO“A brand can be visible in traditional search and still be absent from the answer generated by AI tools,” says Toshiki Matsumura, CEO of MediaReach.
The SEO and generative AI search optimization consultancy separates generative engine optimization (GEO), known in Japan as large language model optimization (LLMO), into two objectives: source citation and brand recommendation, aligning AI visibility with the way buyers now discover, compare and evaluate brands before making decisions.
The distinction is clearest in strategy design. Conventional SEO asks, “Which keywords should we rank for?” MediaReach asks how the brand should appear for a query and where that touchpoint sits in the customer journey. When the objective is citation, it strengthens rankings in retrieval-led environments such as Perplexity and Google AI Overview, where authoritative content is likelier to be selected. When the goal is recommendations, it builds trust signals by having AI read through media coverage, reviews, expert validation and industry recognition.
From there, content architecture, link building, structured data, media outreach and digital PR become coordinated signals that help brands earn visibility inside AI-generated answers.
“We balance SEO and GEO worlds to help brands move beyond ranking high enough to be searched. It increases their relevance, authority and likelihood of being discovered within the answer itself,” says Matsumura.
A Structured System for AI Discovery
How does MediaReach structure optimization strategies for visibility within AI-driven search environments today?
A defined system, grounded in three core pillars, brings GEO to life in practice.
Consolidating proprietary research, academic studies, patent filings and insights from client engagements into a systematized knowledge base ensures that optimization decisions are grounded in continuously updated evidence.
Translating that knowledge into service standardization enables repeatable execution. Documented processes guide GEO diagnostics, Share of Model measurement, content structuring and authority signal mapping, enabling consistent delivery across markets and languages.

Why are measurement frameworks important when evaluating brand visibility across AI search platforms?
Measurement drives execution. MediaReach evaluates AI visibility through Share of Model, citation rate and fan-out query exposure across ChatGPT, Gemini, Perplexity and Google AI Overview. These metrics feed a prompt intent design framework, where content is shaped around how users ask AI to compare, recommend or explain. Embedding-based analysis further identifies how AI systems interpret entities and assign trust. This informs entity disambiguation, claim-and-evidence structures and content architecture that increase citation probability while remaining resilient to model evolution.
Execution in Practice
In what way can AI visibility improvements influence inbound engagement and recommendation outcomes?
In a B2B SaaS engagement, conventional SEO did not translate into AI visibility. Despite stable rankings, the brand remained absent from recommendation queries.
MediaReach responded by expanding third-party media presence to strengthen recommendation signals, restructuring site architecture to clarify entity definition and establishing a consistent press cadence to build a continuous corpus of citable information.
Within six months, AI-driven inbound inquiries increased from 10 percent to 23 percent. The brand also appeared in 15 of 20 key recommendation prompts, improving visibility and sales engagement quality.
Precision as a Competitive Advantage
MediaReach’s frameworks are shaped by its work in Japan, where linguistic nuance directly influences AI interpretation. Variations such as hikkoshi, iten or mūbingu for the same concept can produce different model responses.
This sensitivity to semantic variation strengthens the construction of authority signals, particularly in markets where credibility and accuracy carry greater weight. The approach extends across APAC languages, including Chinese and Korean, where similar variations affect AI interpretation.
Offices in London and Santa Clara provide continuous exposure to Western AI search behavior, helping MediaReach distinguish universal patterns from regional differences and apply both within its frameworks.
Integrated Monitoring and Continuous Adaptation
To support ongoing optimization, MediaReach is developing DolphinX, a platform unifying SEO and GEO measurement. The system tracks Share of Model and citation behavior after model updates, enabling data-driven adjustments.
Named among the Top Generative AI Search Optimization Solutions in APAC 2026 by MarTech Outlook APAC, MediaReach is turning GEO into a measurable, execution-driven discipline, ensuring brands present in the answers shaping modern discovery.
Evaluating Generative AI Search Optimization in the Era of AI-Driven Discovery
The shift from traditional search engines to AI-generated responses is altering how brands are discovered, evaluated and selected. Executives responsible for digital growth now face a dual challenge: maintaining visibility in conventional search while ensuring presence inside AI-generated answers that shape early-stage decision-making.
