*Core concept* · *AI Search Infrastructure*

## Definition

The AI search ecosystem is the network of platforms, models, retrieval systems, and interfaces through which users now discover information — including ChatGPT, Perplexity, Google AI Overviews, Microsoft Copilot, Claude, Gemini, and the growing range of AI-powered assistants embedded in consumer and enterprise products.

## Why It Matters for AI Search

No single platform dominates AI search the way Google dominated traditional search. Brands that optimize for one AI surface while ignoring others are leaving significant visibility on the table. Understanding the ecosystem — who the players are, how they retrieve content, and which queries they own — is the starting point for any AI search strategy.
