Understanding the New Search Landscape

The way people search for information online is undergoing its biggest transformation since Google was invented. Alongside the classic 10 blue links, there are now AI-generated answers that inform users directly – often without them needing to visit a website.

For businesses, this means: You need two different optimization strategies.

Google SEO: The Classic Playing Field

How Google Works

Google's algorithm evaluates websites based on hundreds of factors:

  1. Relevance: How well does the content match the search query?
  2. Authority: How many quality backlinks does the page have?
  3. User Experience: How fast does the page load? Is it mobile-friendly?
  4. Content Quality: Is the content comprehensive and unique?

SEO Success Factors

  • Keyword research and optimization
  • On-page SEO (title tags, meta descriptions, headings)
  • Technical SEO (Core Web Vitals, mobile-first)
  • Link building and authority
  • Content creation aligned with search intent

The Challenge

Google is becoming increasingly competitive. The first organic results often appear only after:

  • Paid ads
  • Featured snippets
  • People Also Ask
  • Google AI Overview
  • Local Pack

ChatGPT SEO: The New Playing Field

How ChatGPT "Searches"

ChatGPT and other LLMs work fundamentally differently:

  1. Training-based: The model "knows" things from its training data
  2. Retrieval-based: Current information is fetched via web browsing
  3. Synthesis-based: Answers are compiled from multiple sources

What ChatGPT Prioritizes

  • Factual accuracy and verifiability
  • Consistent information across multiple sources
  • Authoritative sources (Wikipedia, publications)
  • Clear, structured information
  • Recency (for RAG-based queries)

The Opportunity

Unlike Google, there are no established competitors in ChatGPT SEO yet. Those who optimize now can secure a first-mover advantage.

3. Cross-Channel Effects
