Bobby is an AI product manager and the founder of FirstShelf.AI, a platform that helps marketplace sellers optimize their listings for AI search. He works at the intersection of product and generative engine optimization: every recommendation FirstShelf makes is tested against how ChatGPT, Perplexity, and Google AI Overviews actually retrieve and cite sources. His writing draws on two things most SEO commentary lacks: aggregate data from FirstShelf's GEO audits of real marketplace listings, and week-by-week testing of how AI search behavior changes as models and citation patterns evolve. When the blog cites a number from FirstShelf's own data, the sample size and time period are always disclosed. Bobby covers AI SEO, LLM citation behavior, structured data, and AI search visibility for e-commerce. He shares work in progress on X at @bbbybuilder.
