About this ebook

Search is changing. People no longer scroll through ten blue links, they ask ChatGPT, Gemini, Perplexity, Claude, Copilot, Grok, Meta AI, and DeepSeek, and they trust the answer. If your brand is not cited in that answer, you are invisible.

Cited or Silent is the definitive playbook for Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO), written for the Indonesian market and any brand competing for visibility in AI-powered search. Across 91 chapters, 27 tables, and 148 references, it shows you exactly how AI systems decide what to cite, and how to become the source they quote.

Written by Tessar Napitupulu, founder and CEO of Arfadia and a member of the Forbes Agency Council, this book distills years of frontline work helping enterprises and public institutions earn citations from AI systems. He has led Arfadia since 2008 and built it into Indonesia's pioneer in Generative Engine Optimization since 2023. You will learn how retrieval works, how each engine picks its sources, how to structure content for machine readers, and how to measure GEO results across a 90-day sprint.
