Meeting with Takeshi Gunji, representative of 'Content SEO Lab': The Deepening Future of SEO

A meaningful discussion to opening up the Future of SEO

The other day, I had the opportunity to meet Takeshi Gunji, the representative of Content SEO Lab. I have been consulting with Mr. Gunji on business matters since 2007, and this meeting, which was initially scheduled for one hour, turned into a very meaningful time of about two hours after a long and interesting discussion.

Takeshi Gunji's Career and Achievements

Takeshi Gunji began his activities as a special researcher at the All Japan SEO Association in 2010, contributing to the promotion and development of SEO through paper presentations and seminars at venues such as the Tokyo International Forum.

From 2011, he intensified his consulting work for general companies and SEO service providers. Since March 2017, he has served as a technical committee member of the SEO Certification Examination Committee, overseeing exams and reference books, earning high regard within the industry.

In 2023, he established Contents SEO Lab, offering services based on deeper insights and evidence.

Gunji-san has authored numerous papers, including "Considering Google's Architecture", "Google Search Algorithm Learning Notes", and "Understanding Artificial Intelligence Unlocks the Key to Google's Top Rankings!". These works repeatedly present deep analyses based on Google's algorithms and patent information.

A part of these research results, derived from his unique methodology based on Google patent information, sets him apart from general SEO information and speculation-based insights. Gunji's patents (JP2018-116626, JP2018-101283) attest to his technical depth.

His business experience spans various industries, including health foods, security services, sales promotion, rental fashion, advertising agencies, and entertainment production companies, accumulating a wealth of practical knowledge. This multifaceted practical experience adds depth to his consulting and research.

"CONTENTS SEO LAB" is based in Taito-ku, Tokyo, providing SEO technology and insights to a wide range of clients.

Meeting Highlights

Approaching the Quantification of E-E-A-T

In this meeting, we primarily discussed Google's algorithms and SEO. We particularly focused on the concept of E-E-A-T (Experience, Expertise, Authority, Trust).
Gunji-san's notable approach lies in deciphering how Google quantifies and evaluates these seemingly subjective elements through patent information. The deep insights gained here provided clues for devising more sophisticated SEO strategies, going beyond mere rumors and generalizations.

New Perspectives on Technical SEO

We also had the opportunity to delve deeply into technical SEO.

While much misinformation and speculation circulate online, Gunji-san understands and analyzes Google's mechanisms based on solid evidence from patents.
In this regard, our discussion with Gunji-san helped generate more reliable strategies by grasping the essence of technical SEO.

Future Outlook

After this meeting, we strongly felt the synergy that Gunji-san's deep SEO knowledge and research results from "Contents SEO Lab" could bring to the development and improvement of our AI article generation at Kafkai.

In particular, we are confident that combining Kafkai's advanced AI technology with Gunji-san's deep SEO insights can enable more effective digital transformation, especially in addressing the challenge faced by client companies to efficiently create SEO-strong articles at low cost.

Moving forward, we intend to contribute to the development of the entire industry by providing high-quality SEO solutions through collaboration with "Contents SEO Lab".


Mr. Takeshi Gunji, thank you very much for your valuable time. We sincerely look forward to our future partnership creating new value.
