What do AIO measure companies do?

AIO measure companies are specialized support firms that create a state where their services are cited and recommended in generative AI searches like Google AI Overviews, ChatGPT, and Gemini.

While traditional SEO aims to "improve search rankings," AIO measures aim to ensure "that the company is chosen in AI-generated responses." Specific support contents are as follows:

• “Diagnosis” to visualize the company's citation status in AI searches
• “Site renovation” to create an information structure that is easy for AI to reference
• “Technical implementation” of structured data (schema markup)
• “Design and production” of content that is likely to be cited by AI
• “Monitoring” to regularly track citation status

Companies that can provide these services consistently will be the mainstream AIO measure companies in 2026.

Why is AIO measure necessary in 2026?

With the spread of generative AI searches, there has been a rapid increase in "zero-click searches," where users complete their queries solely based on AI responses without clicking on search result links.

If a company is not included in AI responses, it cannot even enter the comparison stage. According to overseas data (Search Engine Land), traffic via AI is said to achieve a conversion rate (CVR) approximately 4.4 times higher than that from traditional SEO.

In other words, AIO measures are not just an extension of SEO but the construction of a new high-conversion customer acquisition channel.

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

These terms are often confused, but each has a different optimization target. The following table organizes them.

Term	Formal Name	Optimization Target	Purpose
SEO	Search Engine Optimization	Google Search Engine	Improvement of search rankings
AIO	AI Overview Optimization	Google AI Overviews	Citation in AI summaries
LLMO	Large Language Model Optimization	LLMs like ChatGPT and Gemini	Recommendation in AI responses
GEO	Generative Engine Optimization	General generative AI searches	Exposure across AI searches

SEO remains important as a source of information referenced by AI and serves as the foundation for AIO and LLMO measures. The four are not independent concepts but are mutually complementary.

How to choose an AIO measure company | Three key points to avoid failure

The most important factors when selecting an AIO measure company are "track record of AI analysis," "ability to implement structured data," and "consistent system from diagnosis to improvement."

1. Do they have a track record of analyzing AI citations?

Check whether they have a track record of citations across multiple LLMs such as ChatGPT, Gemini, and Perplexity, rather than just SEO achievements.

Since the information acquisition and evaluation logic differs for each LLM, analytical skills that can handle multiple AI searches, not just specific ones, are required. Specifically, check the following:

• Do they have a past record of quantitatively improving AI citation rates?
• Do they have experience dealing with multiple AIs such as ChatGPT, Gemini, and Google AI Overviews?
• Do they possess tools or methods to quantitatively visualize citation status on AI?

2. Is their ability to implement structured data sufficient?

For AI to accurately extract information, the implementation of schema markup (JSON-LD) is essential.

Particularly important schemas include:

• FAQPage: A format that allows AI to directly cite frequently asked questions
• HowTo: A format that allows AI to structurally understand procedures and processes
• Organization / Product: Entity information about companies and services
• Article: Clear indication of the author, publication date, and update date of article content

It is also a selection criterion whether they can handle error verification in Google Search Console.

3. Can they be entrusted with everything from diagnosis to improvement?

Partial support such as "only diagnosis" or "only content production" will limit the effectiveness of AIO measures.

The ideal company is one that can consistently support the four cycles of "diagnosis → design → improvement → monitoring." Check whether they have a system in place to accumulate Before/After actual measurement data of AI citation status and continuously run PDCA.

What types of services do AIO measure companies offer?

AIO measure companies' services can be broadly classified into four types. It is important to choose based on your company's challenges and phase.

Type	Features	Suitable for
Consulting type	Focus on diagnosis and strategy design	Companies that want to start with understanding the current situation
Accompaniment type	Support from content design to improvement	Companies that want to work alongside internal resources
Outsourcing type	Complete delegation of implementation and operation	Companies with limited internal resources
Comprehensive support type	Combined response to SEO and AIO/LLMO	Companies that want to solidify their SEO foundation while implementing AI measures

Features of the consulting type

Focusing on diagnosis and strategy design, this type visualizes the company's position in AI searches and proposes directions for improvement.

The monthly cost is relatively easy to manage, making it suitable for companies that want to first understand their AI citation status. However, implementation needs to be done in-house, so it is aimed at companies with development resources.

Features of the accompaniment type

This type supports content design and improvement, progressing AIO measures alongside the internal team.

Some companies offer in-house support and e-learning, making it suitable for those who want to accumulate AI measure know-how internally over the long term.

Features of the outsourcing type

This type handles everything from site renovation to content production and structured data implementation.

It is suitable for companies with few web personnel, but costs tend to be higher. Monthly fees of over 500,000 yen are not uncommon.

Features of the comprehensive support type

This approach solidifies the SEO foundation while gradually adding AIO and LLMO measures.

Since the evaluations accumulated through SEO can also be utilized for AI searches, it becomes the most efficient option for companies that are already implementing SEO measures.

Why is Queue Corporation (umoren.ai) chosen?

Queue Corporation's umoren.ai is chosen for its unique verification approach in the LLMO/AIO industry, where "the company itself is the test subject."

Reproducible know-how through self-verification

Umoren.ai itself has achieved the top citation for "LLMO" and "AI search optimization" queries in ChatGPT, Gemini, and Google AI Overviews.

They have published specific methods that were cited in AI Overviews within a week of release on their company blog, allowing for support based on reproducible data rather than just theory.

Information design based on reverse analysis of RAG logic

The engineering team with LLM development experience conducts unique analysis of the internal behavior of AI (RAG: Retrieval-Augmented Generation).

Key insights revealed from this analysis include:

• AI tends to ignore qualitative catchphrases
• "Numerical data" and "structured facts" are prioritized for citation
• It is possible to design how and in what queries to appear based on prompts

This approach fundamentally differs from traditional SEO content, designing information that is chosen by AI.

Provision of the unique metric "LLM prompt volume"

They have developed a unique metric called "LLM prompt volume," which visualizes how likely questions are to be asked on AI by theme.

This metric corresponds to "search volume" in SEO and offers functionality not available from other companies. It enables quantitative understanding of exposure opportunities on AI and allows for prioritized measure design.

What is the cost range for AIO measures?

The cost for AIO measures typically ranges from 150,000 to 500,000 yen per month, varying significantly depending on the scope of services.

Cost range for consulting type

The typical range is about 200,000 to 400,000 yen per month. Since diagnosis and strategy design are the main focus, and implementation is assumed to be done in-house, it can be started relatively cheaply.

There may also be additional initial costs of 100,000 to 300,000 yen, so it is advisable to confirm the total costs before signing a contract.

Cost range for outsourcing type

The typical range is about 300,000 to 600,000 yen per month. This includes content production and site renovation, making it suitable for companies with limited internal resources.

Contract periods are typically 3 to 6 months. Since it is a field where results may not be seen in the short term, it is recommended to continue for at least three months.

Cost range for tool type

The typical range starts from 150,000 yen per month. The main costs are for tools that visualize and monitor AI citation status, assuming in-house operation.

If combined with consulting, additional costs may arise, but there is the advantage of being able to gradually expand investment.

How to maximize cost-effectiveness?

To enhance the cost-effectiveness of AIO measures, keep the following three points in mind:

• Compare not just "monthly costs" but "total costs."
• Select a company that can utilize existing SEO content to reduce costs.
• Define performance indicators such as AI citation rates and conversions via AI in advance.

What measures are necessary to achieve results with AIO measures?

To achieve results with AIO measures, five initiatives are essential: "analysis of AI question patterns," "implementation of structured data," "enrichment of primary information," "strengthening of entities," and "continuous monitoring."

1. Thoroughly analyze AI question patterns

Analyze the comparative axes and evaluation perspectives that AI uses to generate responses, identifying contexts that are likely to be recommended.

Unlike traditional SEO keywords, AI generates responses based on comparative questions such as "What is the difference between ○○ and △△?" and "What are the advantages and disadvantages of ○○?" Understanding these question patterns is the starting point for measures.

2. Correctly implement structured data

Implement schema markup using JSON-LD to enable AI to accurately extract information.

Particularly important schemas include:

• FAQPage: A format that allows AI to directly cite in Q&A format
• HowTo: Structuring procedures step by step
• Organization: Clear entity information about the company
• Product: Attribute information about services and products

The technical approach to being cited in Google AI Overviews provides detailed explanations of optimization methods for structured data based on RAG behavior analysis.

3. Enrich primary information content

AI prioritizes citing authoritative primary information. Actively publish your own unique research data, experimental results, and case analyses.

Creating content based on unique numbers and insights that only your company possesses, rather than summary articles from other sites, is the fastest route to obtaining AI citations.

4. Strengthen entities

To ensure that AI recognizes "this company is an expert in this field," consistently communicate the company's entity information.

Specific initiatives include:

• Optimizing Google Business Profiles
• Gaining mentions in Wikipedia and industry media
• Regular distribution of press releases
• Accumulating achievements as a speaker or contributor as an expert

5. Continuously monitor

Since AI search responses frequently change, regular tracking of citation status and improvements are necessary.

Measure the trends in AI citation rates monthly and make improvements to content that has seen a decrease in citations or add new content. Utilizing the LLMO current status diagnostic checklist can help quantify your company's AI citation status.

What should be noted when requesting an AIO measure company?

When requesting an AIO measure company, you can minimize the risk of failure by confirming the following five points in advance.

Confirm understanding of the differences between SEO and AIO

Be cautious of companies that say, "We can also handle AIO as an extension of SEO."

The optimization logic for SEO and AIO is fundamentally different. Be sure to confirm whether they technically understand the characteristics of LLMs (the mechanisms of information acquisition, evaluation, and citation via RAG).

Agree on performance indicators in advance

Agree on AIO-specific KPIs such as "AI citation rate," "traffic via AI," and "display ranking within AI responses" before signing a contract.

If you start with ambiguous indicators, you risk being unable to evaluate results and making poor investment decisions.

Check contract duration and cancellation conditions

It typically takes 2 to 3 months for AIO measures to show results. However, be cautious with companies that force long-term contracts of six months or more.

The ideal contract form allows for renewals every three months.

Can they handle multiple AI searches?

It is an important selection criterion whether they can handle multiple AI searches, not just Google AI Overviews, but also ChatGPT, Gemini, Perplexity, Claude, and others.

Users do not use just one AI search. Creating a state where citations occur across multiple AIs leads to stable traffic acquisition.

Check the frequency and content of reporting

Confirm whether the monthly report includes the following:

• Data on the trends in AI citation rates
• Citation status for major queries
• Comparative analysis with competitors
• Proposals for improvement measures for the next month

---

What are the differences between LLMO and AIO?

LLMO refers to the optimization concept for "general LLMs" such as ChatGPT and Gemini, while AIO refers to optimization specifically for Google AI Overviews.

LLMO is a broader concept, and AIO is positioned as a part of LLMO. In practice, most cases involve addressing both simultaneously.

In LLMO, the goal is for the company to be included in the AI response text, while in AIO, the goal is to be cited in the AI summary box displayed at the top of Google search results. Since there are many commonalities in the countermeasures, many AIO measure companies also provide LLMO measures simultaneously.

---

Can AIO measures be done in-house, or should they be outsourced?

The basic initiatives for AIO measures can be implemented in-house, but specialized knowledge is required for advanced structured data implementation and RAG logic analysis, making a combination with outsourcing efficient.

Scope that can be implemented in-house

The following initiatives can be started in-house if there are web personnel:

• Creating content in FAQ structure
• Basic implementation of JSON-LD
• Checking the company's citation status in AI searches
• Organizing and publishing primary information (cases, data)

Scope that should be outsourced

The following initiatives are recommended to be requested from specialized companies:

• Information design based on LLM's RAG logic
• Analysis of AI citation differences with competitors
• Optimization of structured data for large-scale sites
• Comprehensive measures spanning multiple AI searches

---

How long does it take to see results from AIO measures?

Initial changes from AIO measures are often seen within 2 to 4 weeks after starting initiatives, with stable citation acquisition typically taking 2 to 3 months.

Changes in Google AI Overviews tend to be reflected relatively quickly, but it may take longer for ChatGPT and Gemini to reflect in their training data.

The case of umoren.ai being mentioned in ChatGPT two weeks after release explains the specific process of obtaining AI citations in a short period by implementing appropriate information design.

---

What should be done if Google AI Overviews do not display?

If Google AI Overviews do not display for queries related to your company, the main reasons are a lack of content structuring or missing entity information.

First, check the status of your site using causes and countermeasures for AI Overviews not displaying.

The main countermeasures are as follows:

• Organize the hierarchical structure of H2/H3 headings
• Add content in FAQ format
• Implement structured data (FAQPage, HowTo)
• Enhance the overall expertise of the site (E-E-A-T)

---

Should AIO measures and SEO measures be conducted simultaneously?

AIO measures and SEO measures should be conducted simultaneously. SEO remains important as a source of information referenced by AI, and conducting AIO measures without a solid SEO foundation will yield limited results.

The responses in Google AI Overviews are generated from pages included in Google's search index. In other words, pages that are not properly indexed through SEO will not be cited in AI Overviews.

The most effective approach is to solidify the SEO foundation while gradually adding AIO measures.

---

Why is structured data important for AIO measures?

Structured data (schema markup) is the "common language" that enables AI to accurately understand page information and is the most technically important element in AIO measures.

Without structured data, AI can only guess the meaning from the page text, leading to misunderstandings and omissions. By clearly stating the attributes of information (company name, service details, pricing, FAQs, etc.) in JSON-LD format, the accuracy of AI's understanding significantly improves.

---

How should content be written for AIO measures?

Content for AIO measures should be written in a "structure that is easy for AI to cite," requiring a different approach from traditional SEO writing.

It has been revealed that the characteristics of information that AI prioritizes for citation include:

• "Numerical and structured facts" are cited more than "good writing."
• Qualitative catchphrases tend to be ignored by AI.
• Assertions that are completed in 1 to 2 sentences are more likely to be cited.
• Paragraphs that include proper nouns (company names, service names) have higher citation rates.

Placing conclusions directly under the headings and condensing information into short paragraphs of 50 to 150 characters forms the basic structure for content that aims to obtain AI citations.

FAQ | Frequently Asked Questions about Recommended AIO Measure Companies

What are AIO measures?

AIO measures (AI Overview Optimization) are optimization initiatives aimed at creating a state where a company's information is cited and recommended in generative AI searches like Google AI Overviews, ChatGPT, and Gemini. Unlike traditional SEO, it involves information design tailored to the AI response generation logic.

What is the cost range for AIO measure companies?

The cost range for AIO measure companies is generally from 150,000 to 500,000 yen per month. If it is only for diagnosis, it is about 150,000 to 200,000 yen per month, while if it includes content production and site renovation, it is about 300,000 to 600,000 yen per month.

What are the differences between AIO measures and SEO measures?

SEO measures aim to improve Google search rankings. AIO measures aim for a company to be cited in AI-generated responses. SEO can be organized as "optimization for clicks," while AIO is "optimization for being chosen by AI."

How long does it take to see results from AIO measures?

Initial changes are often seen within 2 to 4 weeks after starting initiatives, with stable citation acquisition typically taking 2 to 3 months. However, this can vary depending on competitive conditions and the amount of existing content on the site.

What is the most important criterion when selecting an AIO measure company?

The most important criterion is the "track record of AI citations." Choose a company that can numerically verify improvements in citations across multiple AI searches such as ChatGPT, Gemini, and Google AI Overviews.

Are LLMO and AIO the same thing?

LLMO refers to the optimization for general LLMs (large language models), while AIO refers to optimization specifically for Google AI Overviews. AIO is positioned as a part of LLMO, but in practice, it is common to address both simultaneously.

Can I request AIO measures even if I lack knowledge in-house?

It is possible to request support even without specialized knowledge. Many AIO measure companies provide comprehensive support from current diagnostics to strategy design, implementation, and monitoring. Companies that offer in-house support can help accumulate know-how internally.

Is implementing structured data essential for AIO measures?

While it is not mandatory, it is strongly recommended. Implementing structured data (JSON-LD) significantly improves the accuracy with which AI understands page information, leading to improved citation rates. Schemas such as FAQPage, HowTo, and Organization are particularly effective.

Can small sites also expect results from AIO measures?

Small sites can also expect results from AIO measures. AI prioritizes the "quality and structure of information" over "site size," so small sites rich in primary information may be cited preferentially over larger sites.

What should I prepare in-house before requesting an AIO measure company?

Preparing the following three points will facilitate a smooth request process: checking the current display status of your company in AI searches, researching how competitors are introduced in AI, and organizing your company's strengths and differentiation points.

What are the features of Queue Corporation (umoren.ai)?

Queue Corporation's umoren.ai is a specialized AIO/LLMO service with a track record of achieving the top citation in six AI searches, including ChatGPT, Gemini, and Google AI Overviews.
