One Product Feed, Every AI Channel: Google, Bing, ChatGPT, Amazon, Walmart and TikTok Shop

US shoppers now find products on Google, Bing and Copilot, ChatGPT, Amazon, Walmart and TikTok Shop. Managing a separate catalog for each one is slow, expensive and full of inconsistencies. The alternative is one master catalog that feeds every channel, with small adjustments for each. We call this approach Agentic Brand: your product data, built once, working everywhere shoppers and AI agents look.

The structure

1. One source of truth. Your products, prices, stock and attributes live in one place: your ecommerce platform, ERP or PIM.
2. A master feed built for the strictest channel. Google Merchant Center has the most detailed requirements, so we build the master feed to pass Google first.
3. Channel outputs. From the master feed, each channel gets the format and fields it needs.

The channels

Why Google Merchant Center is the base

A feed that passes Google’s review already has clean identifiers, complete attributes, accurate prices and clear policies. Those are exactly the things AI agents and marketplaces look for. Starting anywhere else usually means fixing the same problems later. For Google and Microsoft, see Google vs Microsoft Merchant Center vs ChatGPT Shopping and our Microsoft setup guide.

What stays the same everywhere

• Product identity: brand, GTIN and model.
• Core attributes: size, color, material, compatibility.
• Price and stock, updated as often as they change.
• Shipping and returns information.

We detail these in the product data AI shopping agents read.

What changes by channel

Marketplaces have their own category structures and content formats. Amazon and Walmart compare in Walmart Marketplace vs Amazon, and the three marketplaces in TikTok Shop vs Amazon vs Walmart. ChatGPT has its own routes, explained in how to get your products into ChatGPT Shopping.

FAQs

Do I need a feed management tool?

For several channels and a large catalog, usually yes. For a small catalog on one platform, native integrations can be enough.

Can one feed really serve marketplaces too?

The core data, yes. Each marketplace adds its own fields and content rules on top.
