The End of Search

[All earnings will be donated to charity]

The End of Search reveals the invisible revolution reshaping how brands, ideas, and truth itself become visible in the age of intelligent systems.

For decades, marketers optimized for search keywords, backlinks, and content calendars. But today, visibility is no longer decided by search engines. It’s defined by understanding.

In this groundbreaking book, growth strategist Tanguy De Keyzer introduces GEO — Generative Engine Optimization: a new discipline for brands who want to be found inside AI models like ChatGPT, Claude, and Gemini.

Learn how to:
• Redefine visibility beyond clicks and rankings.
• Measure brand cognition using five GEO metrics (PRR, SAI, SDR, TAS, MDI).
• Build systems that make your brand understandable to AI, not just discoverable online.

The End of Search is both a manifesto and a manual for the next decade of marketing — a practical guide for leaders, founders, and creators ready to thrive in the post-search era.

It’s not about ranking higher.
It’s about being remembered in the minds of machines.

Welcome to the invisible revolution.
