Hakuhodo DY ONE Launches an AIO Support Service with “KARTE Blocks”
〜No-code, speedy delivery of website improvements to ensure correct understanding and evaluation by AI〜

Tokyo, May 26, 2026 – Hakuhodo DY ONE Inc. is pleased to announce the launch of an AIO support service leveraging “KARTE Blocks,” the website improvement arm of the KARTE^*1 series, a customer experience (CX) platform offered by PLAID, Inc. This service is designed to help brands enhance their communication capabilities and equity through integrated support in anticipation of AIO, ranging from website optimization to verification for no-code, swift delivery.

Background

The evolution of generative AI in recent years has changed the information-seeking behavior of sei-katsu-sha^*2 into decision-making centered on summaries and recommendations presented by AI. Accordingly, corporate websites now require AI optimization (AIO) to optimize their information structure to ensure correct understanding and evaluation by AI, in addition to the traditional SEO. At the same time, challenges are emerging in the execution phase of initiatives. More specifically, the lead time of a few months needed for assignment adjustment for engineers and actual implementation after the required improvements have been diagnosed remains a bottleneck to the PDCA cycle. Furthermore, the existing practice of directly updating webpages makes it difficult to run A/B tests to verify the effectiveness of initiatives.

Against this backdrop, Hakuhodo DY ONE is launching an AIO support service with KARTE Blocks, building on its experience of supporting numerous companies through the provision of AIO Diagnosis Service^*3. In this service, our team of AIO experts and the team of KARTE specialists work seamlessly together to provide comprehensive support ranging from the development of website strategy in response to information-seeking centered on AI-powered search, to the implementation and assessment of initiatives.

Service features

• Shortening the PDCA cycle and reducing the implementation cost
  We substantially streamline the process ranging from AIO diagnosis to implementation and publication, thus shortening the PDCA cycle from the typical six to eight weeks to three to four weeks. In this way, we minimize the man-hours and costs for revamping, and help companies address their concerns such as: “We’d like to promote AIO but lack resources.” “We don’t think we can overcome the hurdles to implementation.”
• No-Code, swift implementation with KARTE Blocks
  By leveraging KARTE Blocks at the development and implementation phases, we ensure no-code, speedy website revamping, A/B tests and personalization, thus optimizing the customer experience (CX) and ongoing, advanced marketing programs.
• Expertise and support structure as Official Partner
  As an Official Partner^*4, Hakuhodo DY ONE boasts advanced expertise and ample experience in KARTE. We also won Rising Star at KARTE Partner Award 2025, in recognition of the early launch of a collaborative structure and activities, development of solutions and generation of results. Indeed, we have built a support structure that can respond to various needs in utilizing KARTE.
• Promotional structure in support of the advancement of AIO
  ONE-AIO Lab, our research and development unit specialized in AIO, marshals insights, knowledge and specialists company-wide and fuses technological perspectives based on experience in the implementation and operation of generative AI, thereby functioning as enabling infrastructure for the provision of this service.
