Traditional SEO was simple.
👉 Rank your website on Google.
But in 2026, search has changed.
Today users ask:
- ChatGPT
- Google AI Overviews
- Gemini

Instead of searching websites, users are asking AI directly.
That’s why new terms have emerged:

Let’s understand them in the simplest possible way.
The Easy Formula
Think of search in 3 generations:
Generation 1
Google Search
User → Google → Website
Example:

Google shows websites.
Generation 2
Google AI Overviews

Example:
Google directly summarizes:
“Top Bond Cleaning Companies in Brisbane include…”
Generation 3
ChatGPT, Gemini, Claude, Perplexity
User → AI → Direct Answer
Example:
“What are the best bond cleaning companies in Brisbane?”
AI directly answers without showing traditional SERP.
