Search Traffic Increases Up to 3.4x with AI Improvements to Table of Contents and Transcription Features! Towards Voicy, Where 'Voices Are Found'

Voicy released its AI-powered "AI Table of Contents Display" and "AI Transcription" features in September 2025. We are pleased to announce that a survey conducted on over 1,000 channels that showed changes in search traffic, in conjunction with SEO improvements implemented alongside the introduction of these features, revealed that the number of search inflows to broadcast pages increased by up to 3.4 times under specific conditions.

SEO Inflow to Channel Tops Also Increased by 1.15 Times

Furthermore, improvements were observed not only for individual broadcast pages but also for "channel top pages," which serve as the face of a channel. Compared to channels where both "AI Table of Contents" and "AI Transcription" were not set, channels with both features enabled saw a 1.15-fold increase in SEO inflow to their top pages. This indicates that utilizing these features contributes not only to access to single broadcasts but also to overall SEO improvement for the entire channel.

Resolving the "Black Box" of Audio and Seeking Ways to Deliver It

Voicy has continuously sought the optimal way to deliver audio content, filled with the passion and thoughts of personalities, to as many listeners as possible. The "information asymmetry" unique to audio media, where content is unclear until played, has been a significant barrier to meeting new listeners.

To solve this problem, Voicy released its AI-powered "AI Table of Contents" and "AI Transcription" features in September 2025, which visualize broadcast content. This has enabled external search engines to accurately index broadcast content, bringing us one step closer to building a structure where users can find "the story they want to hear now" via search.

Designing Safe Visualization that Preserves the "Intent" of Broadcast Content

Voicy values a system that correctly delivers the primary information transmitted by personalities without compromising its intent. This feature also incorporates a design that balances information visualization with a sense of security.

• Copy Restriction to Prevent "Malicious Snippets": By restricting general users from copying transcription text, we prevent out-of-context citations or inappropriate reprinting, protecting the voices of personalities.

*For companies using the corporate plan "VoicyPro," it is possible to copy text from the administration screen. This allows for smoother multifaceted content deployment, such as utilizing their broadcast content for official articles or SNS posts.

Future Outlook: A Place Where Audio Becomes an Asset and Is Listened to for a Long Time

Broadcasts posted on Voicy are evolving from transient information into "assets" that are listened to over the long term through search. Voicy will continue to maximize the value of "voices" through the power of technology and create an environment where creators can confidently continue to broadcast.
