“GMO AI Optimization Boost” is a new solution designed for the generative AI era that optimizes how information about companies and products is accurately and preferentially referenced and recommended by generative AI platforms such as ChatGPT, Gemini, Claude, Grok, and Google AI Overviews.

Through this service, companies can ensure that their own information is properly reflected in the answers generated by AI, which is expected to expand reach to potential customers and enhance brand value.

Currently, in the field of AI search optimization, there are many concepts and methods with different names and definitions, such as “AIO,” “LLMO,” “GEO,” and “AEO” (each explained below). GMO NIKKO takes an integrated view of these approaches and provides services aimed at the “strategic control and optimization of the visibility of corporate information in the generative AI era.”

AIO:AI OptimizationA collective term for optimization initiatives targeting generative AI as a whole, including LLMO, with the goal of improving answer accuracy and ranking. Compared to LLMO, AIO addresses AI response trends and learning processes from a broader perspective.
LLMO:Large Language Model OptimizationAn approach that optimizes company information so it is more easily referenced and recommended by large language models (LLMs), which form the foundation of generative AI. This includes improving content structure, context, and credibility to make information easier for AI to trust and cite.
GEO:Generative Engine OptimizationMeasures aimed at improving the display ranking and accuracy of information when generative AI such as ChatGPT or Gemini is treated as a search engine. This concept adapts traditional SEO to the context of generative AI to maximize exposure and presence within AI platforms.
AEO:Answer Engine OptimizationOptimization measures for “zero-click searches,” where AI directly presents answers as search results. This includes organizing information so AI can easily select accurate and reliable answers through FAQ structures, schema markup, and similar techniques.

Background to Launching the “Reputation Management Service Using Generative AI”

With the widespread adoption of generative AI, search behavior that involves checking answers from platforms such as ChatGPT and Google AI Overviews is rapidly increasing. For companies, having their own names and services displayed accurately and frequently in generative AI responses is becoming one of the key conditions for competitive advantage.

At the same time, challenges have emerged, such as the difficulty of measuring generative AI responses and insufficient measures to address the risk of misinformation being cited or referenced. In particular, mechanisms to manage generative AI responses from a brand safety perspective have not been sufficiently developed in Japan.

To address these issues, GMO NIKKO, in collaboration with specialized companies including GMO Brand Security, provides a service that detects and corrects reputational risks caused by incorrect answers generated by AI, thereby enhancing corporate value through the development of marketing infrastructure and safety measures for the AI search era.

What is Japan’s First “Reputation Management Service Using Generative AI”

1. Investigation and Analysis of Reputational Risk Detection
 Responses containing company names, service names, and other related keywords are collected from various generative AI services (ChatGPT, Gemini, Claude, Grok, Google AI Overviews, etc.) to detect the following issues. The detected results are visualized by AI model, topic, and severity of expression.

・ Whether responses include misinformation or potential factual errors
・ Whether outdated or already-resolved information is presented as current
・ Whether negative information is excessively emphasized
・ Whether expressions that could damage brand value are included

This makes it possible to clearly identify what needs to be addressed and its priority.

2. Validation of Source Information
The information sources referenced or cited by generative AI are identified and evaluated based on the following points:

・ Whether the sources are appropriate
・ Whether the information is up to date
・ Whether context or nuance has been distorted

This allows companies to assess the quality of the information underlying AI responses and clarify areas for improvement.

3.Reputational Risk Mitigation Support
 When misinformation or excessively negative expressions are detected, GMO NIKKO works in collaboration with partner companies such as GMO Brand Security to provide end-to-end support, including:

・ Organizing, updating, and improving the structure of information on corporate websites and owned media
・ Optimizing FAQs, product descriptions, and press release content
・ Ensuring consistency of information across third-party and review sites
・ Supporting consideration of inquiries or correction requests to AI service providers when necessary

Through this support, companies can detect new reputational risks in the AI search era and resolve them based on data with expert assistance.
