THE ALGORITHM DOESN'T OWE YOU A SALE A Diagnostic Guide to Marketplace Search · 2026 Edition · 57 pages Etsy, Gumroad, Creative Market and Pinterest all publish some version of their own ranking rules. Almost nobody reads them. Sellers repeat advice from a blog post written in 2019 instead — some of it was true once, most of it was never sourced at all, and Etsy's own 2026 guidance now contradicts a lot of it directly. This book only uses what these platforms have actually published, or what has been independently measured. Where something is folklore, it says so plainly. Every ranking factor, eligibility rule and platform quote was verified directly against Etsy, Gumroad, Creative Market and Pinterest's own documentation in August 2026 — not repeated from another guide. This is not a narrative book. It's a diagnostic manual: checklists, comparison tables, and a decision tree you work top to bottom when a listing has stopped performing.
