Monetizing Your Mental Capital, Season 3, Episode 6. Host: Will Christensen. Guest: Damon Sununtnasuk. Recorded March 2026.
Amazon shoppers aren't ranking your listing anymore, they're asking AI for the answer.
In this episode of Monetizing Your Mental Capital, Will Christensen sits down with Damon Sununtnasuk, a returning guest who has sold on Amazon for over a decade (since 2015) and has founded three businesses spanning tech startups, consulting agencies, and consumer goods brands. Damon also works as an AI consultant, building context files and automation briefs for clients.
Damon breaks down Answer Engine Optimization (AEO), the shift from ranking in search results to becoming the answer an AI gives. He walks through the two sides of AEO for Amazon sellers: the Amazon-native side, where Cosmo (the backend attribute system) feeds Rufus (Amazon's AI shopping assistant, now Alexa for Shopping) with high-intent, descriptive phrases instead of old-school short keywords, and the off-Amazon side, where earned media, blogs, and schema markup determine whether AI tools cite your brand at all, even inside the Amazon app itself.
The conversation also covers how to write for AI (short, structured, question-and-answer style content instead of long-form SEO articles), why schema markup helps get your brand picked up by ChatGPT, Gemini, Claude, and Perplexity, his take on LLMS.txt files, the growing role of Reddit in AI citations, and Damon's take on "context stacking" for getting better results out of Claude and other LLMs by layering company rules, founder preferences, business context (CLAUDE.md), and task-specific instructions.
Note: Since this episode was recorded, Google's AI optimization guide (updated June 15, 2026) says Google Search does not use llms.txt or need any special machine-readable file to show a site in Search or its AI features. Rufus is now Alexa for Shopping.
