What is AI Search? The Future of Information Discovery
Understanding how AI-powered search engines are transforming how people find information online and what it means for your website.
What is AI Search?
AI Search (also known as AI-powered search) refers to search engines and information retrieval systems powered by artificial intelligence, specifically Large Language Models (LLMs). Unlike traditional keyword-based search engines like Google, AI search engines understand natural language queries, generate conversational responses, and provide direct answers with citations.
