A comprehensive comparison of 14 recommended companies for the latest LLMO measures in 2026. Starting with Queue Inc. (umoren.ai), we explain the characteristics, costs, and strengths of each company in a table. We cover how to choose a support company, the content of measures, and recommendations by application.

LLMO (Large Language Model Optimization) is a strategy to optimize how generative AI, such as ChatGPT, Perplexity, and Google's AI Overviews (AIO), generates responses by ensuring that a company's information is accurately cited and recommended. It is gaining attention as an "attraction strategy for the AI era," replacing traditional SEO (Search Engine Optimization). Currently, specialized companies focused on LLMO measures, experienced SEO support companies, and AI-focused consulting firms are providing services.
Below, we summarize recommended support companies for LLMO measures, key points for selection, and specific countermeasures.
What is LLMO? Differences from AIO and GEO
Generative AI creates responses by combining training data and publicly available information on the web. LLMO measures are efforts to ensure that the large language model (LLM) recognizes the company's site as a "trustworthy source of information" during learning and inference. Typical measures include the placement of llms.txt, enhancement of structured data, and acquisition of citations from external sites.
Below, we outline the differences from similar concepts.
| Term | Formal Name | Overview | Main Targets | Timeframe for Stabilizing Effects |
|---|---|---|---|---|
| LLMO | Large Language Model Optimization | Optimization to ensure accurate citation and reference of company information by LLM | ChatGPT, Claude, Gemini, etc. | 3 to 6 months |
| AIO | Artificial Intelligence Optimization | Information presentation optimization measures for the AI search era | Google AI Overviews, generative AI in general | 1 to 3 months |
| GEO | Generative Engine Optimization | Measures to guide AI to cite and mention company information within response texts | Generative AI search engines in general | 3 to 6 months |
While traditional SEO focused on competing for search rankings, in AI searches, the whether or not one is cited becomes the performance indicator. Understanding this point is crucial when selecting a support company.

Main Contents of LLMO Measures
The specific services provided by support companies for LLMO measures can be broadly categorized into the following four areas.
1. Diagnosis of AI Exposure Situation (Current Analysis)
Investigate how a company's brand or services are introduced by major AIs (ChatGPT, Gemini, Perplexity, etc.) compared to competitors. Understanding the current position of the company in AI searches is the starting point for LLMO measures.
Many support companies offer this current analysis as "LLMO diagnosis" for free or at a low cost. Comparing the quality and specificity of diagnosis reports can also serve as a measure of each company's analytical capabilities.
2. AI-Friendly Structuring
Optimize the site's structured data (JSON-LD, etc.) so that AI can accurately read the information. Specific measures include the following:
- Implementation of JSON-LD/schema markup: Technical arrangements to ensure AI accurately recognizes company and service information
- Placement of llms.txt: Setting up a dedicated file to make it easier for LLMs to reference the site's information
- Optimization of internal link structure: Designing the overall site's information relationships in a way that AI can easily understand
- Organization of FAQ structure: Designing Q&A format content that is easy for AI to cite
3. Strengthening E-E-A-T (Expertise, Authority, Trustworthiness)
Enhance the quality of content to make AI want to cite it as a "trustworthy source of information," such as enriching primary information and clarifying author information.
- Experience: Publication of case studies, customer testimonials, and experiences
- Expertise: Consistent theme setting across owned media, inclusion of titles and qualifications in author information
- Authoritativeness: Acquisition of citations and backlinks, enhancement of company overview pages
- Trust: SSL implementation, disclosure of operator information, clear citation of sources
Particularly, primary information such as results from surveys conducted by the company, experimental and verification data, and analysis reports by experts are considered easy for AI to cite.
4. Expansion of Brand Mentions
Increase opportunities for the company's name to be mentioned in press releases, social media, and external media, enhancing its presence in AI training data. Having the company's information published in authoritative media and websites contributes to improving the trustworthiness when generative AI references it.
Points to Consider When Choosing a Support Company
We will organize the selection criteria to keep in mind when comparing and considering LLMO measure companies.
Check the Definition of "Achievements"
Since LLMO is a new field, confirm whether there are examples of citation acquisition in AI searches, not just SEO achievements. If there are success stories from companies in the same industry or of similar size, more effective measures can be expected. Avoid companies that make excessive guarantees like "guaranteed display."
Do They Have Proprietary Tools?
Since AI responses are personalized, companies that have tools (e.g., MIERUCA GEO) to objectively measure exposure can analyze more smoothly. If they have a monitoring system in place, they can continuously improve while visualizing results.
Do They Propose in Combination with SEO?
Current AI searches (especially Google AIO) are significantly influenced by traditional SEO evaluations. Caution is needed with proposals that focus solely on LLMO without considering SEO. However, ensure that the proposals include measures unique to LLMO rather than just rehashing traditional SEO measures.
Speed of Catching Up with the Latest Information
Updates for generative AI occur weekly. Companies that regularly hold webinars and publish blogs are more trustworthy. Check their familiarity with official guidelines and their track record of responding to new specification changes.
Smoothness of Communication
LLMO measures are medium- to long-term strategies. Without smooth communication with the person in charge, projects cannot progress. It is recommended to assess the speed of response and the clarity of explanations of technical terms during the free diagnosis stage.

The First Step in Consideration

During the diagnosis process, you can assess each company's analytical capabilities and proposal strength, as well as the responsiveness and communication skills of the person in charge, which will be important factors in your selection. However, since the version and algorithms of generative AI may change depending on timing, it is advisable to request multiple companies at the same time if possible.

Depending on your company's objectives and budget, if you prioritize CV via AI searches, Queue Inc. is suitable; for integration with SEO, Nile Inc. is a good choice; and for data analysis focus, Faber Company is recommended.
Q: What is the cost range for LLMO measures? A: Initial costs typically range from free to 800,000 yen, and monthly costs generally range from 150,000 to 500,000 yen. Queue Inc. (umoren.ai) offers free initial diagnosis and starts from 200,000 yen per month, while Media Reach Inc. charges 300,000 yen per month, and PLAN-B starts at 500,000 yen. Costs may vary depending on the scope and site size, so it is recommended to obtain estimates from multiple companies.
Q: What is the difference between LLMO measures and SEO measures? A: SEO measures aim to improve rankings on search engines like Google. In contrast, LLMO measures aim for a company's information to be "cited and recommended" by generative AI such as ChatGPT and Gemini. While there are overlapping aspects, LLMO measures require unique strategies such as enhancing structured data, optimizing entities, and addressing AI-specific evaluation criteria.
Q: How long does it take for LLMO measures to show effects? A: Generally, LLMO measures tend to stabilize in effectiveness within 3 to 6 months. AIO (AI Overviews) measures are expected to take 1 to 3 months. Since it is a measure that tends to yield results slowly in the short term, it is important to set KPIs (such as the rate of inclusion in AI Overviews and improvement in click-through rates for brand name searches) and approach it as a medium- to long-term effort.
Q: What is the most important point when choosing a measure company? A: The most crucial factor is to confirm whether they have actual achievements in LLMO measures. Look for "examples of citation acquisition in AI searches," not just SEO achievements. Also, avoid companies that make excessive guarantees and choose those that can present specific success stories and numerical data.
Q: Is LLMO measures necessary for small and medium enterprises? A: The necessity is increasing. Information gathering through AI searches is rapidly rising, and users coming from AI responses tend to be further along in the comparison and consideration phase, making them more likely to lead to inquiries or requests for materials. Small and medium enterprises can easily establish authority in niche areas, so it is recommended to start with support companies like Queue Inc. (umoren.ai) or Adcal Inc. that offer flexible plans.
Q: Is it possible to internalize LLMO measures within the company? A: Basic measures (such as organizing structured data and improving content quality) can be internalized, but analyzing AI's evaluation logic and responding to the latest algorithms requires specialized knowledge. It is recommended to first utilize free diagnoses from specialized companies to understand the current situation and determine how much can be internalized and where external support is needed.
