[WACA Kanto Chapter Sponsored] How Much to Entrust to AI Next Year & Year-End Party

Seminar Overview: "How Much to Entrust to AI Next Year" Generative AI is dramatically changing advertising, analytics, and content creation. While this brings convenience, workplace challenges may also be increasing. Questions arise like: “What tasks should be entrusted to AI and what requires human judgment?” “What usage leads to effective results?” “Where are the legal boundaries not to be crossed?” This seminar gathers seven frontline professionals to present the current state and next-year strategies of Web marketing in the AI era. Part 1 covers rapid LP improvements using AI, the newly launched ChatGPT advertising, and AI-driven changes in analysis and production through practical case studies. A lightning talk by a lawyer will address common legal pitfalls when delegating to AI. Part 2 shares site improvement case studies that eliminated internal assumptions through data-driven decisions to achieve results. Part 3 discusses how data analysis teams should evolve amid the AI upheaval. Part 4 delivers practical insights on the role of a “Generative AI Manager” who delegates tasks to AI, generates results, and creates systematic workflows. This year-end seminar updates the dividing lines between the technology to entrust, the ability to judge, and the knowledge to protect. It is recommended not only for certified web analysts but also for those involved in Web marketing at corporations or supporting companies who want to consider how to engage with AI going forward. A year-end party will follow the seminar for networking with speakers and participants. Speakers: Part 1: "Lowering CPA Beyond Advertising—Rapid LP Improvement with AI" Speaker: Teppei Takizawa With rising advertising costs, efforts in operation alone no longer easily reduce CPA. The next step is LP improvement to increase CV counts, the denominator of CPA. Although A/B testing has existed for 20 years, AI has removed implementation barriers, enabling structural page changes verified within days. Based on case studies such as doubling form reach rate and adding about 1,000 annual conversions by changing two CTA characters, this talk explains how to cycle “data and hypotheses” to achieve results. Recommended for those who struggle to reduce CPA despite reviewing ads, have only minor improvements from A/B testing, or want to leverage AI for improvement proposals. Speaker Profile: Teppei Takizawa is a website improvement consultant at NTT Docomo Business X Co., Ltd., and a WACA certified Master Web Analyst. Since launching a print-on-demand business in 2007, growing it to about 200 million yen in two years, he became a web consultant. With nearly 20 years in the web industry, he supports numerous major company site improvements focusing on CRO/LPO/EFO, GA4/GTM, SEO, and LLMO, emphasizing AI-powered diagnostics and content creation. He also teaches and develops materials for certified web analyst courses. https://cvscan.jp/ Part 1: "ChatGPT Advertising Frontline—What Ads Lead to Results in Conversational AI" Speaker: Kazuhiro Hosoda Launched in Japan in August 2026, ChatGPT ads are displayed below answers triggered by conversational context rather than keywords. With no industry averages or keyword targeting, design determines success. This talk covers how to design ad groups and context hints based on user intent, create consistent ads and LPs, measure results with Pixel, GA4, and customer management, and set test budgets based on acceptable CPA, all from a web analytics perspective. Recommended for those wanting to try ChatGPT ads but uncertain about budgets or criteria, search or social media ad operators curious about new platforms, and those responsible for measuring and verifying ad-to-LP conversion effectiveness. Speaker Profile: Kazuhiro Hosoda is CEO of Digimarl Inc. and a WACA certified Advanced Web Analyst. With over 17 years of advertising operation experience, he founded Digimarl in 2016. Operating from Tokyo, Fukuoka, and Okinawa, the company supports 20 platforms, data integration and visualization, and AI applications across multiple industries. He also manages his own restaurant.
