What four pillars of "AI search" are being observed in the market?

In general, the “AI search” area is divided into four different pillars, which are handled by different providers:

  1. AI Overviews : These AI elements are closest to the familiar SERPs.
  2. AI Mode : There are currently very few examples of this available.
  3. AI search engines (such as Perplexity and ChatGPT with web search): Users enter their own prompts, which are then regularly queried in order to create analyses based on them.
  4. AI chatbots (such as Google Gemini or ChatGPT): These work with very large numbers of prompts.
