Amazon 3P: Build, maintain, and connect a clean Amazon catalog.

Third-party selling on Amazon means you own the offer and share the catalog. Every listing you touch is built from two kinds of data: the detail page that every seller of that product contributes to, and your offer — price, quantity, condition, fulfillment. Most catalog problems come from mixing the two up, or from treating a "successful" upload as a finished listing.

This track walks through the four skills that make up day-to-day Seller Central catalog work: understanding product identity, creating listings (one at a time and in bulk), maintaining live listings without getting them suppressed, and building variation families that actually help shoppers choose.
