"Let's Build an English Website" is Wrong: Expert with 30 Years of Web Experience and Support for 1,000 Companies Publishes Book on LLMO Countermeasures

Prismgate Inc. (Headquarters: Yokohama, Kanagawa Prefecture, CEO: Hiromi Shibata), which handles the production and operation of corporate websites, today, June 29, 2026, released the book "100 Practical Techniques for LLMO and AIO [AI Optimization] You Can Do Now" (Shuwa System New Company) authored by CEO Hiromi Shibata. This book distills essential countermeasures, based on verification from the operational sites of approximately 100 companies, into 100 techniques to prevent small and medium-sized enterprises from suffering disadvantages, by identifying the pitfalls of the "LLMO countermeasure vendors" that are proliferating in the AI search era.

The Term "LLMO Countermeasures" Has Been Around for Only About a Year

"LLMO countermeasures" refers to ensuring that generative AI such as ChatGPT correctly recognizes and cites your company. This term has only been widely used for about a year. There is a scarcity of empirical data, and only a very small number of experienced specialists exist, creating a chaotic situation with vendors entering the market one after another to fill the void.

What Shibata finds particularly problematic is the suggestion, "AI's training data is primarily in English, so let's build an English website." Japanese users ask AI questions in Japanese, and AI reads and answers based on Japanese websites. What determines whether AI cites a site is not the language, but whether it clearly states "who is being provided with what, and with what track record." Having received consultations from many companies who lost their domains and received zero inquiries after paying high fees during the previous SEO boom, Shibata felt compelled to write this book, stating, "We must not repeat the same tragedy in the age of AI."

A column detailing the reality of this "English website pitfall" and the proliferation of vendors is now available.

【Key Points of This Book】A "Touchstone" for Identifying Vendors

If SEO countermeasures are about reading "how Google determines rankings," then LLMO countermeasures are about reading "how AI chooses citation sources." Furthermore, AI typically presents only 1 to 3 companies in response to a query, and if you fall behind, you could face a situation where "not being introduced by AI is the same as not existing."

Be suspicious of those who talk about "magic bullets" like "an English website" or "ranking high with special tags."

Vendors who specifically ask about your company's industry and track record are trustworthy; those who push "packages" without looking at the details are dangerous.

Rather than impressive titles, look for whether they can explain in their own words "why AI would choose that company."

And the real countermeasures are always subtle. Instead of "high-quality services," focus on "25 years in business, 1,000 cases handled." Instead of "customer first," focus on "24-hour support, average response within 30 minutes." Simply writing with numbers and specifics transforms information so it's understandable to both AI and customers.

Author's Comment

I wrote this book with the wish that customers, who are amateurs, would not suffer disadvantages by having correct knowledge, as quickly and in the right form as possible.

More important than impressive titles is whether one can explain in their own words "why AI would choose that company." That is the best touchstone for identifying vendors.
