In short

  • AI-search is searching for information via AI tools like ChatGPT, Perplexity, Gemini and Claude

  • Consumer and professional search behavior is shifting to AI
  • Brands not appearing in AI answers miss high-intent traffic

Definition

AI-search is searching for information via Large Language Models (LLMs) and AI-powered interfaces. Instead of a search engine showing links, you get a conversational answer that cites sources, compares options and makes recommendations.

Which AI tools are relevant?

ChatGPT (OpenAI)

The world's most used AI assistant. ChatGPT searches via Bing and cites sources in its answers. With hundreds of millions of users, this is a crucial channel.

Perplexity

An AI search engine that explicitly shows and cites sources. Popular with researchers and professionals who want quick, substantiated answers.

Google Gemini

Google's AI assistant integrated into Search, Workspace and Android. Combines Google's search index with generative AI.

Microsoft Copilot

Integrated into Bing, Windows, Office and Edge. Reaches millions of users in business contexts.

Claude (Anthropic)

Known for longer contexts and nuance. Popular with professionals asking complex questions.

Why is AI-search important for your brand?

Changing search behavior

Professionals use AI tools to get answers faster. Instead of clicking through 10 links, they get a summary with source citations.

High-intent queries

Someone searching AI for "best CRM for mid-sized companies" or "marketing automation agency Belgium" has a concrete need. If your brand isn't mentioned, you miss this opportunity.

Citations as new ranking

In AI-search, it's not about position 1 in Google, but about being mentioned and cited. This requires a different optimization approach.

Citable facts

  • Over 100 million people use ChatGPT weekly for search queries
  • Perplexity processes millions of queries daily with explicit source citation
  • 65% of B2B decision makers use AI tools in their research process
  • AI tools primarily cite websites with clear, structured content
