Product feeds for Amazon, eBay and Google Shopping

NMNorthMountain 30 May 2026 7 min read

Selling on Amazon, eBay or Google Shopping means feeding them an accurate, up-to-date list of your products — a product feed. Done automatically, your listings stay in sync with prices and stock; done by hand, they drift and cost you sales.

What a product feed is

A product feed is a structured file or API stream — titles, descriptions, prices, images, stock, identifiers — formatted the way each channel expects. Each marketplace has its own rules, so the same catalog is shaped differently for Amazon, eBay and Google.

Why automate it

  • Prices and stock stay correct across every channel automatically.
  • No overselling items you no longer have.
  • New products appear on every channel without manual re-entry.
  • Rejected listings get flagged so you can fix data once, at the source.
Fix data at the source: clean your product data once in the shop, and every channel benefits. Patching each marketplace separately is endless work.

Keeping it accurate

A good feed setup runs on a schedule, validates against each channel's requirements, and reports errors. Combined with ERP integration, your single source of truth flows all the way out to the marketplaces.

Frequently asked questions

Which channels can you feed?
Amazon, eBay, Google Shopping and most major marketplaces and comparison engines. Each gets a feed shaped to its specific format and rules.
How often does the feed update?
Typically several times a day, or near real-time for stock. We tune the schedule to how fast your prices and inventory change.
Why do marketplaces reject listings?
Usually missing or invalid data — identifiers, categories, image rules. A good setup validates before sending and flags issues so you fix them at the source.
