Understanding User Search Behavior in the Age of AI: Insights from Knowledge Holdings

In today's digital landscape, understanding user behavior in search engines has become increasingly complex, especially with the rapid rise of AI-powered search tools such as ChatGPT and Perplexity. Knowledge Holdings, headquartered in Tokyo, conducted a survey involving 315 individuals aged between their teens and fifties to uncover current search behavior and information-gathering practices. The results provide essential insights for those involved in SEO and content marketing strategies.

Survey Overview

- Target Group: Men and women across Japan aged between 10 to 50 years old.
- Valid Responses: 315 participants.
- Survey Period: Conducted in May 2026.
- Methodology: Online questionnaire.
- Demographics: 52.4% male and 47.6% female, with the majority being employed (45.0%).

Key Findings

Site Selection Process

The survey revealed that 50.48% of respondents typically consider 2 to 3 sites when making decisions based on search results. When combined with those who only consider 1 site, about 60% finalize their choices from the top 3-4 results. This suggests a general reluctance to venture beyond a few selected sources as users tend to fear information bias from a narrow viewpoint, while also recognizing the lengthy time investment required to analyze multiple listings.

Impressions of Top Sites

When asked about their impressions of higher-ranked sites, 43.17% reported feeling these were likely popular and chosen by many, while 23.81% found them credible. This positive perception of rankings emphasizes the intertwined relationship between site popularity and perceived trustworthiness. However, an awareness of possible advertising practices also exists, with 8.25% expressing skepticism.

Post-AI Search Behavior

Following an AI search, 40.32% of participants indicated they would conduct a secondary search on Google, and 13.33% would check multiple sites for confirmation. This behavior indicates that nearly half of users are not solely relying on AI-generated answers, instead opting for traditional search engines to validate information.

Decreased Engagement with Search Results

The introduction of AI search has led to a noticeable reduction in users’ engagement with search results, with approximately 45% reporting they view fewer results post-AI integration. This trend suggests a shifting preference towards AI for simpler queries, diminishing the role of traditional search engines for straightforward informational needs.
