PRODUCT RESEARCH

PDF · 27 May 2026

The document is a detailed instructional manual for UK Amazon FBA sellers on how to conduct data‑driven product research before purchasing inventory. It stresses that successful sourcing is not about cheap or high‑ROI items alone, but about aligning demand, competition, profit margin, ROI, Buy Box stability, seller count, Amazon’s presence, brand/category restrictions, hazmat and IP risk, review quality, price and sales‑rank history, offer‑count trends, stock levels, and variation/bundle/multipack structures with the seller’s capital, experience and risk tolerance. The guide walks through each factor, explains why common shortcuts (e.g., relying on a single sales rank, low seller count, or a flashy profit figure) are misleading, and provides practical checks using tools like Keepa and SellerAmp. It also warns against over‑specialising in a single category and encourages a flexible, evidence‑based mindset. Throughout, Warren’s voice offers a pragmatic, cautionary tone, urging sellers to build a complete evidence picture before buying.
