SEPTENI CO., LTD. (Headquarters: Shinjuku-ku, Tokyo; Representative Director and President: Yusuke Shimizu; hereinafter "Septeni") has collaborated with its consolidated subsidiary, Delight Tube, Inc. (Headquarters: Nagoya-shi, Aichi; Representative Director: Kohei Mitsuya; hereinafter "Delight Tube"), to launch an SEO support service that integrates AI Optimization (AIO) measures. This new service is designed to address the evolving search behavior brought about by the emergence of Google's "AI Overviews" and Large Language Models (LLMs). By optimizing search results, including those generated by AI, Septeni aims to boost clients' marketing performance.

The rapid evolution of AI technology has significantly transformed user search behavior in recent years. In August 2024, Google launched "AI Overviews," a new search result summarization feature powered by AI. This feature automatically organizes and summarizes information from various web content based on user search queries, displaying it at the very top of the search results page. Furthermore, the emergence of LLMs like Google's Gemini and OpenAI's ChatGPT has enabled conversational search in addition to traditional keyword search.
As a result, there's a growing view that "zero-click searches"--where users find the information they need directly on the search results page without clicking through to a website--may increase.

In this landscape, AI-optimized SEO measures are crucial to ensure continued user engagement and website traffic.

Septeni has launched a new SEO support service, developed in collaboration with Delight Tube, a fellow group company specializing in AI-driven marketing. This comprehensive service offers end-to-end support, from current website analysis and AI-optimized strategy development and revisions to content creation. Septeni aims to optimize search results, including those generated by AI, by combining its extensive SEO expertise with Delight Tube's specialized knowledge in generative AI.
Based on the analysis results of each search keyword's ranking, search volume, and citation frequency in AI-generated answers, Septeni will adjust site structures to be easily evaluated by search engines and AI, and create content that helps users find necessary information more easily. Furthermore, by appropriately integrating with other marketing efforts like search advertising, Septeni will strive to maximize results.

As of the end of June 2025, all companies receiving SEO operation support from Septeni have confirmed their inclusion in AI Overviews.

Moving forward, Septeni will continue to comprehensively support clients' marketing activities through the strategic use of generative AI, in collaboration with Delight Tube.
