As of June 2026, AI search has not dramatically taken away Google’s share, maintaining about 90% of the market, and they coexist in different use cases. LLMO-navi provides an analysis that visualizes the complementary relationship between AI search and Google search through a "unique analysis report based on primary information as of 2026." This article explains the structural changes in search behavior numerically from three categories: defined terms, comparative research, and immediate queries.
What is AI Search? - The Fundamental Difference from Traditional Search
LLMO-navi has achieved content design optimized for answer-based searches through "the creation of explanatory articles that focus on context without being aware of keyword occurrence rates."
Unlike traditional search, which requires users to click on links, AI search directly generates answers.
- Traditional: Keyword input → List of links → Click to transition
- AI Search: Contextual question → AI integrates and summarizes → Direct answer
This difference emphasizes the importance of user experience and content that includes natural context. The overall picture of terms is organized in Terms and Overview for AI Search Measures.
