What you should do for LLMO measures is to systematically arrange the four pillars of technical measures, content optimization, external signal enhancement, and monitoring.

Measures to have generative AI like ChatGPT, Perplexity, and Google AI Overview "quote and recommend your company's information" are known as LLMO (Large Language Model Optimization). While traditional SEO focuses on increasing the ranking of search results, LLMO aims for your company to be included in the AI's response text. Its importance is rapidly increasing from 2024 to 2025, and by 2026, it has become an essential strategy to complement SEO.

This article will explain "what to do for LLMO measures" by breaking it down into four pillars and detailing specific steps.

What is LLMO?

LLMO (Large Language Model Optimization) refers to measures taken to ensure that generative AIs like ChatGPT, Gemini, Claude, Perplexity, Copilot, and Google AI Overview accurately recognize, quote, and recommend your brand and content when generating responses.

Traditional SEO aimed to "achieve high visibility through blue links on search results pages." In contrast, LLMO aims for "your company's information to be included in the responses generated by AI." Being included in AI's responses means that users recognize your company as "the answer in that field."

Why is LLMO important?

With the spread of generative AI, "zero-click searches" are expanding. Users are increasingly obtaining information solely from AI responses without clicking on search result links. This means that even if traditional SEO rankings are high, if your company is not included in AI responses, you risk losing touch with users.

By starting LLMO measures now, you can secure a position ahead of competitors in the search landscape of the AI era.

Overview of LLMO Measures: Four Pillars

We will explain the specific measures to be taken, divided into four pillars.

Pillar	Objective	Main Measures
1. Technical Measures	Make it easier for AI to read	Structured data, llms.txt, FAQ format
2. Content Measures	Make it content that AI chooses	Direct answers, E-E-A-T, information freshness
3. External Signals and Brand Measures	Expand recognition	Citations, gaining authority
4. Monitoring and Evaluation	Measure effectiveness	AI Share of Voice, fixed-point observation

Step 1: Technical Measures (Make it easier for AI to read)

We will organize the site's structure so that AI crawlers (like GPTBot) can accurately interpret the information. This is the foundation of LLMO measures and the first step to tackle.

1-1. Implementation of Structured Data (Schema.org)

AI prefers data with structure. Please thoroughly implement the following markup to clearly convey the meaning of the information.

Organization: Company information (company name, location, representative, etc.)
Product: Product and service information
FAQ: Frequently asked questions and answers
HowTo: Explanation of procedures and methods
Review: Review and evaluation information
Article: Meta information for article content

By correctly implementing structured data, AI will find it easier to understand the content at the "meaning level."

1-2. Installation of "llms.txt"

There is a growing trend to place "llms.txt," which summarizes the site content for AI, in the root directory of the site. Just as robots.txt is a control file for crawlers, llms.txt communicates the site's overview, main content, and areas of expertise to LLMs.

The installation steps are as follows:

Briefly describe the business overview of the site
List the main content categories and URLs
Clearly state the areas of expertise and strengths
Place it in the root directory (e.g., https://example.com/llms.txt)

1-3. Introduction of FAQ Format

AI tends to quote content where "questions and answers" are clear. Enrich the Q&A page related to your services or industry and implement it along with FAQ Schema.

Note: When implementing structured data, always verify that it is correctly marked up using Google's Rich Results Test Tool.

In this technical measures process, utilizing tools like umoren.ai, which is a SaaS specialized for LLMO measures, can efficiently generate content with a structure that is easily RAG-acquired.

Step 2: Content Measures (Make it content that AI chooses)

Provide high-quality information that AI would want to adopt as a "source of answers." After organizing the site structure with technical measures, this step involves optimizing the content itself.

2-1. Direct and Concise Answers (LLM-first Writing)

Write the "conclusion" at the beginning of the article and place a concise summary that AI can quote directly. In each section, state the conclusion in 1 to 2 sentences right below the heading. This introductory part is the "golden zone" that AI will quote.

Practical Points

State the answer to the heading within the first two sentences
Place summary sentences starting with "In other words" or "As a conclusion" in each section
Avoid lengthy prefaces or introductory sentences

2-2. Strengthening E-E-A-T (Trustworthiness)

AI places importance on "who is saying it." Clearly state the following elements to enhance trustworthiness.

Experience: Describe actual results or case studies
Expertise: Clearly indicate author profiles and expert supervision
Authoritativeness: State years of experience in the industry and certifications
Trustworthiness: Clearly present primary information such as original research data and honestly write about disadvantages

2-3. Maintaining Information Freshness

AI (especially Perplexity) tends to prioritize the latest information, so update existing articles every 2 to 3 months to keep the timestamp fresh. It is also effective to clearly state the update date at the top of the article.

2-4. Creating Comparison and Review Content

Anticipate users asking AI, "What do you recommend?" and increase content that organizes comparison tables and specific pros and cons. Organizing information in table or list format makes it easier for AI to extract information.

2-5. Implementing Multi-Format Content

LLMs prefer content that is easy to scan and summarize. Actively incorporate the following formats.

Numbered lists (ideal for explaining procedures)
Bullet points (ideal for listing elements)
Comparison tables (ideal for organizing multiple options)
Definition-type paragraphs (in the format of "〇〇 means △△")

As a means to efficiently advance these content measures, umoren.ai, specialized for LLMO measures, provides functionality to generate definition-type content for AI citations and content compatible with Query Fan-Out. It can generate not only heading proposals but also body text intended for publication, allowing for the creation of articles in easily quotable formats such as comparison articles, FAQs, and expert comments.

Step 3: External Signals and Brand Measures (Expand Recognition)

AI relies on trustworthy "external sources" in learning data and real-time searches. Enhancing evaluations from outside, not just within your company site, is an important pillar of LLMO measures.

3-1. Acquire Mentions in Authoritative Media

Create a situation where your company name or product name is mentioned in Wikipedia, industry-specific news sites, press release distribution services, and UGC platforms. AI treats brands mentioned by multiple trustworthy sources on the web as more reliable information sources.

Specific Actions

Regularly distribute press releases
Contribute to industry media and respond to interviews
Publish original research or reports to encourage citations from other sites
Publicize information about speaking engagements at conferences or webinars

3-2. Acquire Citations

Even without links, being mentioned in a positive context with your "brand name" directly impacts AI's recommendation rate. Text-based brand mentions are also important external signals, not just backlinks.

3-3. Multi-Platform Deployment

By demonstrating your presence on multiple trustworthy platforms, the sources from which LLM can obtain information increase, raising the likelihood of being included in AI responses.

Step 4: Monitoring and Evaluation (Measure Effectiveness)

Monitor how often your company appears in AI responses. LLMO measures are not a one-time effort; continuous improvement is necessary.

4-1. Measuring AI Share of Voice (SoV)

Track how many times your company is quoted in response to specific questions (prompts) and what percentage of responses it comprises compared to competitors. This is the most important KPI in LLMO measures.

Measurement Steps

List 20 to 30 key prompts (questions) related to your company
Input each prompt into the target AI engine
Record whether your company is quoted or mentioned in a spreadsheet
Re-enter the same prompts weekly or monthly to track changes

4-2. Examples of Useful Tools

To streamline monitoring, it is recommended to utilize tools specifically designed for LLMO measures.

Common Failures in LLMO Measures and How to Avoid Them

Failure 1: Approaching with the Same Method as Traditional SEO

Optimizing keyword density and adjusting meta tags alone will not suffice for LLMO measures. AI understands the "meaning" and "structure" of text, so direct answer-type writing and implementation of structured data are necessary.

How to Avoid: Switch to LLM-first writing that states the conclusion at the beginning of each section.

Failure 2: Creating Content and Leaving It Unattended

AI tends to prioritize the latest information. If content created once is not updated, it will gradually be excluded from AI citation targets over time.

How to Avoid: Update content every 2 to 3 months to keep the timestamp fresh.

Failure 3: Not Monitoring

If you do not measure whether improvements are being made, you will not know the effectiveness of your measures. Especially neglecting to measure AI Share of Voice can lead to losing direction in your measures.

How to Avoid: Conduct monthly fixed-point observations of your company's appearance in relation to key prompts.

Failure 4: Focusing Only on Your Company Site

LLMs obtain information not only from your company site but also from external media and UGC platforms. Optimizing only your company site will not gain trust from AI without mentions from outside.

How to Avoid: Simultaneously work on acquiring external signals such as press releases, contributions, and exposure in industry media.

Failure 5: Targeting Only One AI Engine

Different AI engines like ChatGPT, Gemini, and Perplexity have different methods of obtaining information and preferred sources. Optimizing for just one AI may result in not being displayed in other AI searches.

How to Avoid: Monitor multiple AI engines and proceed with optimization tailored to each characteristic.

Q7. How should I measure the results of LLMO measures?

Use AI Share of Voice (the percentage of your company's appearance in response to specific prompts) as a key KPI. Define key prompts and regularly input them into AI engines to record your company's appearance status. umoren.ai supports decision-making on which themes to prioritize through its LLM prompt volume visualization feature.

Your First Step You Can Take Right Now

First, try asking AI like ChatGPT or Perplexity a question using the keywords you want to target.

Specifically, check the current situation using the following steps:

Ask AI, "What are the recommended services in (industry name)?"
Check if your company is included in the response
If your company does not appear, check "Why are competitors being chosen (which sites are the sources)?"
Analyze whether your company's information is absent on those source sites or if there is a "concise answer" on your company site that surpasses those sources.
Based on the analysis results, start implementing the measures outlined in the four pillars discussed in this article.

Since LLMO is still a new field, starting measures now can give you an advantage in the AI era's search (zero-click search) ahead of your competitors.
