Ladylyn Bue outlines a 9-step process for conducting product research for Amazon FBA selling. The process involves browsing Amazon categories and using Helium10 Xray to identify top-selling products, ensuring products meet criteria and checking for patent/trademark issues, searching Alibaba for supplier information, using Amazon's profitability calculator to estimate profits, and reviewing product reviews to identify areas for improvement. The overall goal is to identify high-demand products that can be sourced and sold profitably on Amazon.
