The era of being recommended by humans is over. The era of being recommended by AI has begun. And most brands are not ready. When customers ask ChatGPT, Claude, Gemini, or Perplexity which company to hire, which product to buy, or which expert to trust, AI does not search a ranked list. It returns the brands it already considers authoritative. If your brand is not producing the signals AI systems recognize as credible, you are invisible. It does not matter how good your work actually is.

Authority Engineering: How to Become the Brand AI Recommends is the field guide for closing that gap. Drawing on fifteen years of digital marketing work across e-commerce, healthcare, professional services, and B2B technology, Adam Chronister lays out a systematic framework for building the distributed authority signals that AI, search engines, journalists, and customers use to decide who is credible. This is not theory. It is the same playbook Chronister uses with clients today.

Inside the book, listeners will learn:

• Why traditional SEO is no longer sufficient and what replaces it.
• How AI models build their internal map of who to trust.
• The Four Pillars of AI-era authority and how to engineer each one.
• How to use PR, podcasts, content, and consensus signals to compound visibility.
• How to measure whether a brand is gaining ground in AI search.

This book is for business owners, marketers, founders, and agency leaders who recognize that the rules of brand visibility are being rewritten in real time. The window to build AI-era authority before competitors catch on is open now. It will not stay open long.

The brands that win in the AI era will not be the ones with the biggest budgets. They will be the ones that understand the new rules earliest, build the right signals consistently, and become the answer AI gives by default.
