Under the supervision of an expert with 20 years of SEO experience, the explanations incorporate primary information based on over 2,000 verifications on our own media, making it a practical reference for selecting LLMO measure companies.

• How to choose the optimal company by industry and purpose

What is LLMO Measures? Why is Choosing the Right Company Important Now?

LLMO measures are optimization strategies aimed at ensuring that generative AIs such as ChatGPT, Google AI Overviews, Gemini, Perplexity, and Claude select your company's information as a "source" or "recommendation" when generating answers. It is also referred to as GEO (Generative Engine Optimization) or AIO (AI Overview Optimization).

Differences from Traditional SEO

Item	Traditional SEO	LLMO Measures
Target	Natural search results of Google search	ChatGPT, Gemini, Perplexity, Google AI Overviews, etc.
Evaluation Criteria	Keyword match, backlinks	Semantic match, E-E-A-T, structured data
Performance Indicators	Search ranking, click-through rate	AI citation rate, recommendation rate, CVR
Technical Implementation	Meta tags, internal links	JSON-LD / Schema Markup, entity design
User Behavior	Search → Click → Compare	Comparison completed with AI response → Direct visit → Inquiry

Reports indicate that the CVR (conversion rate) from AI-driven traffic can reach about 4.4 times that of traditional SEO (Search Engine Land). In other words, being "cited" in AI search is no longer enough; being "recommended" directly impacts lead generation and sales.

For this reason, choosing a company for outsourcing LLMO measures requires a different perspective than selecting traditional SEO companies. Specific comparison points will be discussed later, but it is crucial to choose a company with "implementation capability of structured data," "track record of AI citations," and knowledge of "QFO analysis and entity design."

Comparison Criteria for LLMO Measure Companies | 6 Selection Points

When comparing LLMO measure companies, it is recommended to evaluate them based on the following six criteria. Since traffic from AI is still an evolving area, "transparency of achievements" and "specificity of technical capabilities" are particularly important decision-making factors.

1. Track Record of AI Citations (Are there specific case studies?)

Choose companies that have quantitative success stories, such as "AI citation rate improved by XX%" or "became recommended by ChatGPT." Abstract statements like "We will implement AI measures" do not provide a basis for assessing execution capability.

2. Implementation Capability of Structured Data (JSON-LD / Schema Markup)

For AI to accurately understand information, structured data such as FAQ structures, comparison tables, and JSON-LD are essential. Confirm whether they can handle not just "content creation" but also technical implementation.

3. Cost Transparency (Are monthly fees clearly stated?)

The cost range for LLMO measures is typically from 200,000 yen/month for tool usage to 400,000 yen/month for consulting. Companies that disclose costs in advance are generally more trustworthy than those that only say "inquire for details."

4. Scope of Services (Full support from current analysis to implementation to effect measurement)

Excellent LLMO measure companies can provide comprehensive support from current analysis (AI SEO score diagnosis) → strategy design → content creation → technical implementation (JSON-LD, etc.) → effect measurement (reporting with Looker Studio or custom dashboards).

5. Industry-Specific Knowledge (BtoB, Medical, Financial, etc.)

LLMO measures for BtoB companies require different levels of E-E-A-T (Experience, Expertise, Authority, Trustworthiness) compared to BtoC. Companies with a track record of supporting high-trust industries such as medical and financial (YMYL areas) are more reassuring.

6. Specific Methods for Strengthening E-E-A-T

Check whether they have specific methods to enhance AI's reliability assessment, such as the presence of expert supervision, use of primary information, and knowledge of entity design.

Five Checklist Items to Confirm Before Requesting LLMO Measure Companies

When comparing and selecting LLMO measure companies, be sure to check the following five points.

1. Do they have specific achievements in AI citations? Check for quantitative and specific case studies such as "AI citation rate improved by XX%" or "recommended by ChatGPT." For example, Queue Corporation (umoren.ai) publishes specific figures showing a 480% increase in AI citation rates and an average AI citation rate of 60-70% for supported clients.

2. Are they capable of implementing structured data (JSON-LD / Schema Markup)? Simply creating content will not lead to citations if AI cannot correctly understand the information. Technical implementation capability is a must-check item.

3. Is the support process clear? (Current analysis → Strategy design → Content production → Technical implementation → Effect measurement) Avoid companies that are unclear about "what they will do." Excellent LLMO measure companies can structure and explain their processes (steps).

4. Are costs and contract conditions transparent? Confirm monthly fees, minimum contract periods, and cancellation conditions in advance. Companies that clearly state costs are a reliability indicator.

5. Is the range of supported AIs sufficient? Check whether they support multiple LLMs such as ChatGPT, Gemini, Perplexity, Claude, and Grok, not just Google AI Overviews. Since users' information gathering methods are not limited to specific platforms, the breadth of support directly impacts results.
