Founders and marketers trying to understand how AI-driven discovery changes search.

What is SEO?

SEO optimizes content for traditional search engines to earn clicks.

Signals include:

  • Rankings

  • Traffic

  • On-page and technical quality

  • Authority and backlinks

What is GEO?

Generative Engine Optimization focuses on being referenced or cited by AI systems.

Key signals:

  • Trustworthiness

  • Structure and clarity

  • Freshness

  • Verifiable facts

The goal is being used in answers, not ranking.
