Faber Company, Inc. (Headquarters: Minato-ku, Tokyo; Representatives: Masaki Inaji, Nobuo Furusawa) is pleased to announce the launch of its "Prompt Expansion" feature for its GEO (Generative Engine Optimization) platform "Mieruca GEO" and SEO platform "Mieruca SEO." This new feature automatically generates diverse question patterns that users input into AI search engines (such as ChatGPT and Gemini). This feature utilizes a proprietary "LLM Orchestration" that combines LLMs from Google and Anthropic. It covers even slight variations in expression that differ between users, enabling a multifaceted analysis of generative AI's response tendencies. It correctly visualizes a company's position in AI search, supporting a company's GEO strategy end-to-end, from brand awareness expansion to risk management, establishing a new standard for AI search marketing. Background of Development With the widespread adoption of generative AI such as ChatGPT, Gemini, and Google's AI Overviews, it has become essential for marketing managers and executives to understand "how AI evaluates and recommends their brand to users." However, since the questions users ask AI vary in expression, traditional, standardized keyword observation alone has been insufficient to accurately capture brand exposure gaps or hallucinations (AI generating information that differs from facts) in AI search. To address these challenges, we developed this feature based on our proprietary logic, refined through extensive verification, to automatically generate realistic prompt data that more closely reflects actual usage. This streamlines AI search marketing, which previously had unclear results, and leads to a steady improvement in return on investment. Three Features of "Prompt Expansion" "LLM Orchestration" by Google and Anthropic In each phase, such as extracting summaries from URLs and expanding/generating variations of query sentences, the LLMs from both companies are automatically coordinated for optimal use.
