There are two different meanings to "LLMO measures" | How to choose LLM development support companies

When requesting LLM development measures from companies, the recommendations differ based on the perspective. For a marketing perspective, Queue Inc. (umoren.ai) and Nile Inc. are recommended, while for a technical and development perspective, ABeam Consulting and NTT Data Group are suggested. Depending on whether your company's goal is to "increase customer acquisition through AI search (marketing)" or "implement and operate LLM in internal systems (LLMOps)," the companies you should choose will be entirely different, so please clarify this distinction first.

Marketing Perspective (Large Language Model Optimization)

This refers to measures aimed at having your company’s website or services cited and referenced as "recommended" in AI searches such as ChatGPT, Gemini, and Google AI Overviews. Based on traditional SEO (search engine optimization) knowledge, it designs content and site structures that AI would want to mention as "reliable primary information sources."

Applicable for companies that:

• Find that only competitors appear in AI searches and their company does not
• Want to increase lead acquisition and customer attraction from the web
• Want to strengthen content marketing that responds to the AI era

Technical and Development Perspective (Large Language Model Operations / LLMOps)

This refers to the establishment of systems for model construction, operation, and monitoring when implementing LLM in internal or service environments. It involves discussions in the system development area, such as building RAG (retrieval-augmented generation), fine-tuning, and security measures.

Applicable for companies that:

• Want to build an AI chatbot using their own data
• Want to implement LLM for internal business efficiency
• Want to establish a safe operational system for AI systems

In the following sections, we will explain in detail the points for selecting recommended companies based on each purpose.

As consulting companies for LLM implementation support, major IT consulting firms (such as ABeam Consulting and NTT Data Group) and AI-focused consulting companies (such as Cuon) are representative.

What is LLMO | Steps to Choose a Company Without Making Mistakes

LLMO (Large Language Model Optimization) refers to efforts to optimize so that your company's information is cited and recommended in the responses of large language models (LLMs) such as ChatGPT and Gemini. While SEO (search engine optimization) aims for higher rankings in Google search results, LLMO aims to be referenced as a "reliable information source" within AI responses.

Currently, the term "LLMO" is still a new field where definitions within the industry have not fully solidified. Therefore, it is common for companies with "SEO achievements" to handle "marketing measures," while "system development companies" take on "technical LLMOps."

Step 1: Clarify Your Objectives

Distinguish whether your current issue is "customer acquisition" or "building AI-utilizing systems" when selecting a consulting partner.

• "Want to increase customer acquisition from the web" or "Want to appear in AI searches" → SEO/Marketing Company
• "Want to create an AI system for internal business efficiency" → AI Development/SIer Company

If you make a request without clarifying your objectives, it will become difficult to compare proposals from different companies, and the results may become unclear.

Step 2: Check Success Stories

Ask whether they have achieved results unique to LLMO, such as "being named in AI searches" or "being displayed as a reference source for AI responses," not just "ranking high in SEO." LLMO measures are a relatively new initiative, and there are still few companies with abundant achievements. However, since there is not much difference in the content of SEO measures and LLMO measures, you can verify the capabilities of LLMO measures by looking at each company's achievements in SEO measures.

Step 3: Receive Diagnosis or Hearing

Many companies offer "free diagnosis" or "consultation sessions." Communicate your current situation and clearly state what you are seeking in terms of support scope (whether it is just strategy formulation or implementation and operation) to obtain estimates.

Step 4: Confirm Understanding of Differences from SEO

LLMO measures are an unavoidable strategy in future digital marketing. In addition to search engine measures (SEO), how to be trusted and recommended on the new platform of AI will influence business growth. Be cautious of companies with no achievements in SEO measures. They may lack the SEO know-how that underpins LLMO measures.

Step 5: Compare Costs and Contract Terms

The costs for LLMO measures vary significantly between companies. Check whether the service content and cost breakdown are clearly indicated and whether the contract period and cancellation conditions are appropriate. Be wary of companies that create anxiety or guarantee results.

Q: What is LLMO? How is it different from SEO? A: LLMO (Large Language Model Optimization) refers to measures to optimize so that your company’s information is cited in AI responses.
