This article will fairly compare the eight major companies that provide LLMO (Large Language Model Optimization) consulting, detailing how to choose based on company size and purpose.
What is LLMO Consulting?
LLMO consulting is a specialized support service that optimizes content and technology so that company information is accurately quoted and recommended within the responses of generative AI such as ChatGPT, Gemini, and Perplexity. While traditional SEO (Search Engine Optimization) aims for high rankings in Google search results, LLMO aims for the appearance of the company name or service name directly in the AI's response text.
As of 2026, the number of users utilizing AI search is rapidly increasing, and companies, especially BtoB and SaaS firms, are facing the challenge of "not appearing when asked about their company by AI." LLMO consulting is gaining attention as a service that supports adaptation to this new marketing channel.

How to Choose an LLMO Consulting Company | 5 Comparison Points
When choosing LLMO consulting, it is important to compare and consider the following five points.
Point 1: High Level of LLMO Specialization
AI search optimization requires a different knowledge system than traditional SEO. Understanding LLM-specific technologies such as RAG logic, prompt volume analysis, and AI citation structure is the most critical criterion. Companies that handle LLMO as an extension of SEO and those that specialize in LLMO tend to show differences in the depth of their responses.
Point 2: Balance of Tools and Consulting
There are companies that provide only analysis tools, those that provide only consulting, and those that offer a combination of both. If you have a dedicated marketing person in your company, you can operate with a tool-centric approach, but if you need support from strategy design to execution, services that include consulting are more suitable.
Point 3: Range of Supported AI Platforms
There are several major AI searches, including ChatGPT, Gemini, Claude, Perplexity, Copilot, and Google AI Overview. Some services may only support specific AIs, so check which AI your target users are utilizing to confirm the range of support.
Point 4: Transparency of Achievements and Performance Indicators
Companies that can demonstrate results with specific figures such as AI citation improvement rates and CV improvement rates are more reliable. It is important to check whether they can present data before and after improvements, rather than just providing qualitative explanations like "we are addressing AI issues."
Point 5: Cost-effectiveness and Contract Structure
Contract structures vary by company, including monthly fixed, performance-based, and spot contracts. Be sure to check for minimum contract periods and any additional costs. It is important to judge not only by cost but also by the expected returns (increased inquiries via AI search, improved brand recognition, etc.).
Recommended Selection Based on Purpose and Situation
If Your Company Name Does Not Appear at All in AI Searches
If currently, your company name does not appear when asked to ChatGPT or Gemini, it is effective to request a company with specialized knowledge in LLMO. Queue Corporation (umoren.ai) has a track record of improving AI brand recommendation rates from 0% to 90%, and there are reports of being selected as a recommended candidate by ChatGPT within 14 days of site publication. They offer comprehensive support from LLM strategy formulation to execution, site analysis, KPI setting, and regular reporting.
If You Want to Start AI Search Measures Alongside SEO
If you are already implementing SEO measures and want to add AI search measures, companies with knowledge in both SEO and AI optimization are suitable. Consulting with companies like Nile and Faber Company, which have a strong foundation in SEO, is one option. Additionally, Queue Corporation also provides a hybrid approach of SEO × LLM optimization, supporting integrated assistance with SEO measures.
If You Need a Large Volume of Content Production
If the quantity of content is a priority, companies like Willgate and LIG, which have abundant content production resources, are options. However, in AI search, the "structure" of content is important, not just the "quantity," so confirm whether they can produce content in formats that are easily acquired by AI.
If You Want to Strengthen Lead Acquisition via AI as a BtoB or SaaS Company
BtoB and SaaS companies often have products that are easily compared in AI searches, making them areas where LLMO effects are likely to emerge. Queue Corporation has implementation achievements in areas significantly impacted by AI search, such as SaaS / IT, BtoB companies, and marketing companies, reporting a CV improvement rate of 4.4 times for AI search inflows. They are suitable if you aim to be specifically recommended by AI during the comparison phase.
If You Want to Keep Costs Down and Try First
If you want to try LLMO measures on a small scale first, it is reasonable to utilize services that offer free initial diagnoses. Queue Corporation (umoren.ai) provides free initial diagnoses and can start with a plan from 200,000 yen per month. They also allow for tool-only usage, enabling a gradual increase in investment.
