AI Search

AI Search

AI search refers to search experiences powered by large language models that generate direct, synthesised answers to user queries rather than returning a ranked list of links.

AI search represents a fundamental shift in how people find information online. Traditional search engines — built on index-and-rank architectures — return a list of web pages and let the user decide which to visit. AI search systems synthesise information from multiple sources and present a single, conversational answer.

Major AI search products include Perplexity AI (a dedicated AI search engine), Google AI Overviews (integrated into Google Search), ChatGPT with web search enabled, and Microsoft Copilot. Each uses a combination of pre-trained LLM knowledge and real-time web retrieval to generate responses.

For brands, AI search changes the rules of discoverability. A brand that ranks #3 in traditional search still gets clicks. A brand that isn't cited in an AI search answer gets nothing — the user receives a complete answer and often doesn't need to visit any website.

Why it matters for marketers

Industry analysts project that AI search will handle a growing share of informational queries over the next 3-5 years. Brands that build AI search visibility now will have a significant first-mover advantage as adoption accelerates.

Frequently asked questions

Is AI search replacing traditional search?

Not fully, at least not yet. Traditional search still handles the majority of queries globally. But AI search is growing rapidly, particularly for informational and research-intent queries where users want synthesised answers rather than links to browse.

Which AI search platforms are most important for brands?

As of 2026, the highest priority platforms are Google AI Overviews (due to Google's search market share), Perplexity AI (fast-growing dedicated AI search), and ChatGPT (largest installed base of AI assistant users).
