What Is AI Search?

Definition

A category of search tools that use generative AI to produce conversational answers instead of returning a ranked list of links — includes ChatGPT Search, Perplexity, and Google AI Overviews.

Why It Matters

AI search is reshaping how buyers research before purchasing. Instead of clicking through five blog posts, users increasingly ask ChatGPT or Perplexity for a synthesised answer. Brands that are cited in those answers enter the consideration set; brands that aren't may become invisible even to buyers actively looking for them.

How It Works

AI search tools crawl the web, index content, and when a user asks a question, retrieve relevant sources and generate a natural-language answer with citations. Unlike traditional search, there's no list of ten results to skim — the AI produces a composite answer drawing from a handful of sources. Being cited requires content that is authoritative, recent, factually clear, and accessible to AI crawlers.

Real-World Example

A B2B SaaS company that ranks #4 on Google for "best project management software Australia" gets cited in Perplexity's answer for the same query, driving qualified trial signups from users who never visit Google results at all.
