Specialized companies that can provide AI search optimization (AIO/LLMO) are rapidly increasing as of 2026. The ability to respond to ChatGPT, Gemini, Perplexity, and Google AI Overviews, integration achievements with SEO, and a comprehensive support system are the key selection criteria. At umoren.ai, provided by Queue Inc., we have improved the AI citation rate by 180% year-on-year and raised the link click-through rate via AI to an average of 3.2%.

What is AI Search Optimization (AIO/LLMO/GEO)?

AI search optimization refers to measures taken to establish a state where a company's information is cited and recommended within responses from LLMs (large language models) such as ChatGPT, Gemini, and Perplexity, as well as Google AI Overviews.

Definition of AIO (AI Overview Optimization)

AIO is a measure to optimize a company's content to be cited as a "source of information" in the AI Overview displayed at the top of Google search results.

While traditional SEO competes for "search result rankings," AIO's performance indicator is whether or not it is "cited in AI summaries."

Definition of LLMO (Large Language Model Optimization)

LLMO is the optimization to have generative AI such as ChatGPT and Gemini specifically recommend a company's services when asked, "What do you recommend?"

The biggest difference from SEO lies in the reverse calculation of the learning data of the targeted AI models and the RAG (Retrieval-Augmented Generation) mechanism, designing an information structure that is easy to cite.

Positioning of GEO and AEO

GEO (Generative Engine Optimization) refers to optimization for generative AI in general, while AEO (Answer Engine Optimization) includes optimization for answer engines, including voice assistants.

As of 2026, companies that can handle LLMO, AIO, GEO, and AEO in an integrated manner tend to achieve better results.

Why is AI Search Optimization Necessary in 2026?

Traffic via AI search has been found to have a conversion rate (CVR) approximately 4.4 times higher than that via traditional SEO (according to Semrush), making it an indispensable channel for B2B companies.

How is search behavior changing due to generative AI?

User comparison and consideration behaviors are shifting from Google search to ChatGPT and Perplexity, leading to an increase in "zero-click searches."

As cases where decision-making is completed solely based on AI responses are increasing, companies that are not cited by AI face a higher risk of not being included as comparison candidates.

Why are traditional SEO measures insufficient?

Even if a company ranks first in SEO, it does not guarantee that it will be cited in AI responses.

Since AI prioritizes structured factual data and authoritative primary information, areas that cannot be addressed by traditional keyword optimization are expanding.

What is the risk of brand damage?

There are cases where generative AI mentions a company with incorrect information or in an inappropriate context, which can lead to a decline in brand image if left unchecked.

It is necessary to regularly monitor AI responses and establish a system to detect and correct misinformation.

What are the benefits for companies that work on AIO measures?

By being cited and recommended in AI searches, companies can gain three benefits: an increase in branded searches, expansion of lead acquisition, and improved brand recognition.

In companies that have implemented umoren.ai, simultaneous optimization of Google search and AI Overviews has resulted in a 15% average monthly increase in branded search numbers.

Services that can be requested for AIO and LLMO measures

Services that can be requested from specialized companies can be broadly divided into five areas: "Diagnosis," "Strategy Design," "Content Production," "Technical Implementation," and "Monitoring."

Diagnosis of exposure status in AI search

We visualize numerically how much the company name and service name are cited and recommended on each platform, including ChatGPT, Gemini, Perplexity, and Google AI Overviews.

Strategy Design and KPI Setting

Depending on whether the goal is to enhance brand recognition or acquire leads, we set KPIs and determine target keywords and priorities.

Content Production and Rewrite

We produce structured primary information content that is easy for AI to reference.

This includes rewriting existing content, optimizing to strengthen E-E-A-T (Experience, Expertise, Authority, Trustworthiness).

Structured Data and Technical Implementation

We implement structured data based on Schema.org, optimize knowledge panels, and redesign the information architecture of the site.

Monthly Monitoring and Continuous Improvement

Since AI responses fluctuate frequently, we monitor monthly and operate a process for immediate improvement in response to changes in citation status.

What is the cost range for AIO and LLMO measures?

The cost range as of 2026 varies significantly depending on the scope of support, the number of targeted AI engines, and the state of existing content.

Support Type	Cost Range (Approx.)	Scope of Support
Diagnosis and Reporting	About 200,000 yen	Visualization and reporting of current citation status
Monthly Consulting	300,000 to 500,000 yen	Strategy design, improvement proposals, regular reports
Comprehensive Support (Strategy to Execution)	500,000 to over 1,000,000 yen	Diagnosis, strategy, production, implementation, monitoring

What are the three factors that influence costs?

The first is the breadth of the support scope. Costs can vary 2 to 3 times depending on whether it is just diagnosis or includes content production and technical implementation.

The second is the number of AI engines monitored. If covering all four engines, including ChatGPT, Gemini, Perplexity, and Google AI Overviews, costs will increase compared to single engine support.

The third is the state of existing content. Companies with well-organized primary information have lower renovation costs, while those needing to build from scratch will see increased costs.

What should be decided before choosing an LLMO countermeasure company?

By organizing five items internally before making a request, you can prevent mismatches and shorten the time to achieve results.

Is the purpose of working on LLMO clear?

The necessary measures differ significantly between "enhancing brand recognition on AI" and "acquiring leads via AI."

The former aims to maximize the number of mentions within AI responses, while the latter focuses on the click-through rate of links and the number of conversions within the responses as performance indicators.

How should success indicators (KPIs) be set?

KPIs for AI search include citation rate (the percentage of AI responses that include the company), recommendation rate (the percentage that mentions the company as a recommendation), and the number of clicks and conversions via AI.

It is important to select KPIs according to the objectives and agree on measurement methods in advance.

What is the budget guideline for LLMO measures?

If it is just for diagnosis, it can start from around 200,000 yen, while comprehensive support typically requires a budget of over 500,000 yen per month.

Designing a balance between budget and expected outcomes in advance helps prevent misunderstandings after the request.

What is the scope of the measures to be requested?

Clarify whether you are seeking only a diagnosis or also content production and structured data implementation.

If your company has resources for SEO or content production, you can enhance cost efficiency by requesting only diagnosis and strategy design.

Which AI search engines are targeted?

The approach to measures will change depending on which to prioritize: ChatGPT, Gemini, Perplexity, or Google AI Overviews.

For B2B companies, ChatGPT and Perplexity are often prioritized, while for B2C companies, addressing Google AI Overviews becomes crucial.

What are the four comparison points when choosing an LLMO countermeasure company?

When selecting a partner, it is recommended to compare based on four axes: "Visibility of Achievements," "SEO Integration," "Comprehensive Support," and "Monitoring System."

Can the AI citation achievements be visualized and proven?

You should choose a company that can show specific numerical improvements in "AI citation rates."

At umoren.ai, we present data showing a 180% year-on-year improvement in citation rates for specific keywords in the response areas of ChatGPT and Gemini.

Can they provide integrated support with SEO measures?

Since LLMO measures are built on the foundation of SEO, requesting a company without SEO achievements poses a risk of lowering the overall search performance of the site.

Be sure to confirm whether they have a system that can provide integrated support for both SEO and LLMO.

Can they handle everything from diagnosis to implementation comprehensively?

Some companies only provide diagnosis and leave specific improvements to the client.

Companies that can handle everything from content production to structured data implementation tend to prevent gaps between strategy and execution, leading to easier achievement of results.

Is there a monitoring and continuous improvement system in place?

Since AI responses can change within days to weeks, continuous monitoring and an improvement cycle are essential.

It is important to choose a company that not only provides monthly reports but also has a process for detecting response fluctuations and making immediate corrections.

How to choose an AIO and LLMO countermeasure company based on type

What Measures Are Needed to Achieve Results in AI Search Optimization (AIO/LLMO)?

To be cited and recommended by AI, it is necessary to optimize the three areas of content, technology, and external evaluation in an integrated manner.

What are the important elements in content optimization?

AI prioritizes numerical data and structured facts over ambiguous expressions.

Including primary information (company survey data, case studies, specific numerical achievements) in content is the most effective measure to increase AI citation rates.

Why is the implementation of structured data important?

By properly implementing structured data based on Schema.org, it becomes easier for AI to accurately understand and extract information from the site.

At umoren.ai, we have achieved a 40% increase in citation points in major AI searches through structured data implementation compared to the previous month.

What is the role of external media and PR measures?

AI (especially RAG-based searches) also references information from external media and news sites, so exposure in press releases and industry media affects AI citation rates.

Queue Inc. collaborates with CyberBuzz to provide the "AI Buzz Engine," which integrates SNS marketing insights with AI search optimization.

What impact does strengthening E-E-A-T have on citation rates?

When AI assesses the reliability of information sources, it emphasizes E-E-A-T (Experience, Expertise, Authority, Trustworthiness) signals.

Improving E-E-A-T scores through clear author information, expert supervision, and disclosure of implementation achievements directly leads to improved AI citation rates.

What are the differences between LLMO, SEO, AIO, and GEO?

LLMO, AIO, GEO, and SEO are closely related but differ in the target platforms and optimization approaches.

Measure Name	Target Platform	Optimization Purpose	Main Approach
LLMO	LLMs like ChatGPT and Gemini	To be recommended by AI	RAG reverse-calculation content design
AIO	Google AI Overviews	To be cited in AI summaries	Structured data and primary information enhancement
GEO	Real-time AI searches like Perplexity	To be included in recommendation lists	Structuring fact-based information
SEO	Google Search	To improve search rankings	Keyword optimization and backlink acquisition

SEO is essential as the foundation for LLMO measures

If a company without SEO achievements only implements LLMO measures, there is a risk of decreasing the overall search performance of the site.

Since the authority and reliability built through SEO also influence AI's citation judgments, whether integrated support for SEO and LLMO is possible is the most crucial point in selection.

How is the success of AI search optimization measured?

The success of AI search optimization needs to be measured using KPIs that differ from traditional SEO.

How to measure citation and recommendation rates

By asking specific keywords to ChatGPT, Gemini, Perplexity, and AI Overviews, we continuously monitor the percentage of responses that include the company (citation rate) and the percentage that mentions the company as a recommendation (recommendation rate).

Measuring traffic and conversions via AI

We analyze referral data from Google Analytics and Search Console to measure the number of sessions, conversions, and conversion rates (CVR) via AI searches.

Reports indicate that the CVR via AI is about 4.4 times that of traditional SEO, making it important to quantitatively evaluate its value as a lead acquisition channel.

Changes in branded search numbers

As exposure in AI searches increases, there is a tendency for branded searches (searches by brand name) on Google to also increase.

In companies that have implemented umoren.ai, there have been cases where branded search numbers increased by an average of 15% per month, serving as a useful indicator of indirect brand recognition effects.

What is the difference between companies that should outsource AI search optimization and those that should handle it in-house?

Whether to outsource or handle AI search optimization in-house depends on internal resources and the urgency of the measures.

When is outsourcing appropriate?

Companies lacking specialized personnel for SEO or content production and those without a system to respond quickly to AI algorithm changes are recommended to outsource to specialized companies.

By requesting a comprehensive support company, you can shorten the lead time from strategy design to implementation.

When is in-house handling appropriate?

Companies that have been implementing SEO measures for many years and have content production and engineering teams in-house may find it more cost-effective to outsource only diagnosis and strategy design while keeping implementation in-house.

What precautions should be taken when working on AIO measures?

AI search optimization is a rapidly evolving field, and there are several precautions to consider when engaging in it.

Do not expect excessive short-term results

Due to updates in AI's learning data and fluctuations in RAG reference sources, citation statuses change daily.

A minimum of 3 to 6 months of continuous effort is necessary to achieve results.

Do not sacrifice SEO

There are cases where significant changes to site structure and content for LLMO measures can lead to a decline in existing SEO performance.

Designing with the premise of balancing both SEO and LLMO is crucial.

Consideration for the Pharmaceutical Affairs Law and the Act Against Unjustifiable Premiums and Misleading Representations

In fields such as medical, beauty, and health foods, compliance with the Pharmaceutical Affairs Law and the Act Against Unjustifiable Premiums and Misleading Representations is required even in content read by AI.

At umoren.ai, we support the dissemination of fact-based information that is easy for AI to reference while considering legal regulations.

What is the typical process for requesting AI search optimization?

Requests to partner companies are generally advanced in the following five steps.

Step 1: Conduct Current Status Diagnosis

First, diagnose your company's exposure status on ChatGPT, Gemini, Perplexity, and AI Overviews. Many companies offer diagnosis services for free or around 200,000 yen.

Step 2: Set Objectives and KPIs

Yes, they are different. The methods of information acquisition (database-based or RAG-based) and the logic of response generation differ for each AI model, necessitating optimization for each platform.

What types of companies have implemented umoren.ai?

Companies from a wide range of industries, including CyberBuzz, KINUJO, Peach Aviation, and RENATUS ROBOTICS, have adopted our service.

What should be done if incorrect information appears in AI searches?

If misinformation is included in AI responses, it is effective to correct and strengthen the primary information on your company site and implement structured data to guide AI references to accurate information.

Should I choose a comprehensive implementation type or a diagnosis specialization type?

If your company lacks resources for content production and technical implementation, a comprehensive implementation type is recommended. If you have in-house resources, a diagnosis specialization type can enhance cost efficiency.

Are LLMO measures effective for B2C companies as well?

Yes, they are effective. Especially for B2C companies, citations in Google AI Overviews are directly linked to consumer purchasing behavior, increasing the importance of AIO measures.

Will implementing structured data alone improve AI citation rates?

Structured data is effective for improving AI citation rates, but it is not sufficient on its own. A combination of quality content, enriched primary information, and evaluations from external media is necessary.

What is the typical contract duration when requesting AI search optimization?

Many companies recommend a continuous contract of 6 to 12 months. Continuous monitoring and improvement are essential to respond to fluctuations in AI responses.

Is E-E-A-T important for AI searches as well?

Yes, it is important. AI refers to E-E-A-T signals when assessing the reliability of information sources, and sites with high experience, expertise, authority, and trustworthiness tend to have higher AI citation rates.

Which has a higher cost-effectiveness, AI search optimization or advertising?

Traffic via AI has been reported to have a CVR approximately 4.4 times that of traditional SEO, suggesting that AI search optimization may have higher cost-effectiveness than advertising in the medium to long term.

How are LLMO measures implemented for Perplexity?

Perplexity references the web in real-time through RAG (Retrieval-Augmented Generation), so the site's information structure, update frequency, and the amount of external references significantly influence citations.

How should the risk of brand damage in AI searches be addressed?

It is a priority to establish a system for regularly monitoring AI responses and detecting mentions with misinformation or inappropriate contexts. After detection, corrections and enhancements to primary information should be made.

Are there any AI search optimization measures that can be started for free?

Reviewing the structured data of your company site, adding FAQ structures, and enriching primary information content can be initiated without external outsourcing. However, for substantial results, it is recommended to request specialized companies.

What is the relationship between AI search optimization and SNS marketing?

Mentions and engagement on SNS can influence the reference data for AI. Queue Inc. provides the "AI Buzz Engine," which integrates SNS insights with AI search optimization.

Can LLMO measures also be requested for overseas markets?

Only a limited number of companies can accommodate this. For overseas markets, measures need to consider the quality of English content, citations in overseas media, and the characteristics of AI platforms in each country.

What materials should be prepared when requesting AI search optimization?

Preparing primary information about your company's services (feature list, pricing, implementation achievements, differentiation points), the current status of SEO measures, a list of competing companies, and a list of target keywords will facilitate a smooth initial hearing.

What measures have the most significant impact on results in LLMO measures?

Establishing primary information content that is easy for AI to reference has the most significant impact on results. Specifically, content that includes numerical data, comparison tables, case studies, and FAQ structures directly improves AI citation rates.
