How to Choose an LLMO Consulting Company
When selecting an LLMO support company, it is essential to carefully evaluate the technical understanding of generative AI, achievements and expertise, and compatibility with your company's challenges. As this is a new area, having clear criteria for identifying a reliable partner is crucial. To avoid mistakes, please select based on the following points.
Is there a technical understanding of AI?
Whether there are consultants who understand the mechanisms of LLM (Large Language Model) is one of the most important criteria. Confirm whether they understand the internal operating principles of AI, such as the retrieval logic of RAG (Retrieval-Augmented Generation), how entities are recognized, and how structured data is processed. Be cautious of companies that merely claim "AI compatibility" on the surface.
Is there compatibility with SEO?
It is also important to have knowledge of traditional SEO (keyword strategy, structured data, E-E-A-T). LLMO measures are an extension of existing SEO strategies, and companies without a foundation in SEO will see limited effectiveness if they only implement LLMO. Many experts agree that companies without an SEO business should be avoided.
Are there specific achievements?
Check for specific success stories in "AI search" (such as citation examples in AI Overviews or ChatGPT). It is important to choose companies that can demonstrate quantitative achievements, such as "how much the AI citation rate improved" and "on which AI platforms results were achieved."
Check the scope of services and support system
LLMO measures encompass diagnosis, strategy design, content production, structured data implementation, and monitoring. Clearly define the support scope necessary for your company and choose a company that can cover it. The range of services varies among companies, from those that only provide diagnosis to those that offer ongoing support.
Assess costs and ROI
It is also important to evaluate cost-effectiveness in advance. Since LLMO is a medium- to long-term endeavor, check whether there is a system to evaluate ROI over a span of 3 to 6 months, not just short-term results.
Cost Estimates for LLMO Measures
The costs for LLMO measure services vary significantly depending on the scope of the request and the size of the site. As of 2026, the general market rates are as follows.

| LLMO Diagnosis (Detailed) | 200,000 to 1,000,000 yen | Varies based on the number of target keywords and site size |
| Ongoing LLMO Support | 200,000 to 1,000,000 yen per month | From strategy design to content production and operational improvement |
