LLMO countermeasure companies are specialized firms that assist in optimizing the recognition and citation of corporate information by generative AI such as ChatGPT and Gemini. They are broadly categorized into two types: "Marketing-oriented (AI search optimization)" and "Security-oriented (LLM vulnerability countermeasures)."

This article organizes the overall picture of LLMO countermeasure companies, compares key firms by purpose, and comprehensively explains everything from preparation before requests to practical procedures and common mistakes.

What are LLMO countermeasures? Basic definitions and two contexts

LLMO (Large Language Model Optimization) countermeasures are often discussed in two main contexts: "Marketing aspects (optimization for citation by AI)" and "Security aspects (countermeasures for AI vulnerabilities)".

Marketing aspects (also known as GEO and AIO)

This service optimizes websites so that generative AI like ChatGPT, Gemini, and Perplexity can "cite and reference" corporate information when generating responses. It is also referred to as "GEO (Generative Engine Optimization)" or "AIO (AI Optimization)."

While traditional SEO focuses on ranking optimization in search engines, LLMO emphasizes how information is recognized and cited by generative AI, representing a new way of thinking.

Security aspects (LLM security)

This area involves diagnostics and countermeasures to prevent prompt injection (information leakage due to malicious input) and misinformation generation (hallucination) in corporate AI utilization. The main services include vulnerability diagnostics and penetration testing based on international standards (OWASP Top 10 for LLM).

Why is LLMO countermeasure important now?

There has been a rapid increase in people gathering information through generative AI, and users coming from AI responses are often further along in the comparison and consideration phase, making it easier for them to lead to inquiries and requests for materials. This trend is supported by overseas data, and LLMO countermeasures are becoming an essential strategy in corporate marketing.

Type	Purpose	Main Measures
LLMO	To ensure that LLMs like ChatGPT correctly recognize and recommend corporate information	Content optimization, structured data, entity design
SEO	To achieve high rankings in search engines	Keyword optimization, internal linking, backlink acquisition
AIO	To ensure that all AI (including voice AI) recognizes corporate information	Comprehensive measures of LLMO and SEO
GEO	To ensure citation in generative AI-powered search engines like AI Overviews and Perplexity	Content structure design focused on AI citation

What type of countermeasures are you looking for? Criteria for judgment by purpose

When searching for LLMO countermeasure companies, it is crucial to clarify your company's objectives first.

If you want to increase access to your corporate site or have your company recommended in AI searches, then type 1 (marketing-oriented) companies are suitable. It is common to request this as an extension of SEO. Currently, many SEO consulting firms are promoting marketing support using the term "LLMO," but since this is a new field, it is advisable to carefully check their track record (such as actual cases reflected in AI responses).

If you want to enhance the safety of the AI chatbot you have implemented or are concerned about data leakage, then consulting with type 2 (security-oriented) companies and undergoing vulnerability diagnostics (red teaming) is appropriate.

Steps to request LLMO countermeasure companies: 5 steps

Step 1: Clarify the purpose of LLMO countermeasures

The most important thing is to clarify the purpose of LLMO countermeasures.

Specific actions:

• Organize whether you want "to be correctly recognized in AI searches," "to increase natural inflow to your corporate site," or "to ensure the safety of the implemented AI."
• Determine whether you need marketing-oriented or security-oriented countermeasures.
• Set tentative KPIs (AI citation counts, CV numbers, security scores, etc.) that you want to achieve.

Note: If you request without clarifying your purpose, it will become difficult to compare proposals from different companies, and the results may become unclear.

Step 2: Apply for LLMO diagnosis

Many companies that provide LLMO countermeasures offer an "LLMO diagnosis" service that allows you to understand your current situation in AI searches. Since many offer this for free or at a low cost, it is recommended to apply for LLMO diagnoses from multiple companies first.

Specific actions:

• Request diagnoses from 2-3 companies at the same time (as the AI algorithms may change depending on timing).
• Evaluate not only the diagnosis results but also the analyst's analytical skills, proposal abilities, and communication skills.
• unoren.ai offers a free initial diagnosis, so you can start by understanding your current situation.

Note: Since it serves as an entry point to generate interest in the service, the depth of the diagnosis may vary by company.

Step 3: Compare proposals and achievements

After receiving the diagnosis results, compare the proposals from each company.

Specific actions:

• Check whether there are actual cases reflected in AI responses.
• Confirm the types of LLMs they support (ChatGPT, Gemini, Claude, etc.).
• Compare the clarity of the pricing structure and cost-effectiveness.
• Check the contract scope (coverage, deliverables, costs, duration, cancellation conditions).

Note: Since LLMO is a new field, the scope of services and pricing structures can vary significantly by company. It is wise to avoid companies with ambiguous contract terms.

Step 4: Execute the measures

After contracting with the selected company, execute the specific measures.

Specific actions:

• Design a strategy based on the current situation analysis (decide target keywords, content design policy).
• Optimize the information structure to be easily evaluated by AI (structured data, internal link design).
• Create AI citation content and rewrite existing content.
• Check progress and results in regular meetings.

Note: It is important not to think "outsourcing means I can leave everything to them," but to align understanding of the content and progress of the measures.

Step 5: Measure effectiveness and improve

Quantitatively measure the effectiveness of the implemented measures and cycle through improvements.

Specific actions:

• Regularly check AI citation counts, session numbers, and CV numbers from AI searches.
• Compare changes before and after measures and add improvement measures.
• Evaluate results from a medium to long-term perspective (3-6 months).

Note: The effects of LLMO do not appear immediately. It takes time for AI model updates and index reflections, so avoid making judgments based solely on short-term results.

Four checkpoints when choosing LLMO countermeasure companies

1. Does the company have a wealth of experience in LLM optimization? -- Check for actual cases where AI responses have cited them and the improvement metrics for citation rates. It is important to assess whether the company can analyze the "factors" that led to those results, not just the "mention rate."

2. Does the company have the capability to respond to generative AI searches? -- Confirm whether they can broadly respond to major generative AIs such as ChatGPT, Gemini, Claude, Perplexity, and Google AI Overviews. Companies like unoren.ai that support over 6 AI searches are reassuring.

3. Is the pricing structure clear? -- The cost range for LLMO countermeasures is typically 200,000 to 1,000,000 yen for diagnosis and about 200,000 to 1,000,000 yen for monthly consulting. Since it varies based on the number of target keywords, site scale, and support scope, it is a judgment factor whether they can clearly show the basis for their estimates.

4. Does the company have know-how regarding AI content utilization? -- Not just being AI-compatible, but if the company is strong in overall marketing utilizing AI, more strategic measures can be expected. Check whether they can propose structures that are easily obtained by RAG and Query Fan-Out compatibility, demonstrating an understanding of AI mechanisms.

Common mistakes and how to avoid them

Mistake 1: Requesting without clarifying the purpose

There are cases where inquiries mix up marketing-oriented and security-oriented needs. Clarify beforehand whether you want to "increase exposure in AI searches" or "enhance the safety of the AI system" before making a request.

Mistake 2: Neglecting to verify achievements

Since this is a new field, some companies may have limited achievements. Even if they claim to offer "LLMO countermeasures," if there are no actual cases reflected in AI responses, the effectiveness is unclear. It is essential to confirm specific improvement metrics and cases.

Mistake 3: Equating SEO with LLMO

While there are overlapping aspects between SEO and LLMO, to have your brand recommended in AI searches, investment in public relations and brand marketing elements is also necessary. Understand that SEO measures alone will not suffice.

Mistake 4: Expecting only short-term results

LLMO countermeasures are a medium to long-term endeavor. It takes time for AI model updates and index reflections, so continuous measures for at least 3-6 months are necessary.

Mistake 5: Completely outsourcing without retaining internal know-how

If you fully outsource, internal knowledge of LLMO will not accumulate. Actively share information in regular meetings and strive to understand the content of the measures to build a foundation for future in-house production.
