Product feed optimization for Google Merchant Center and ChatGPT Shopping
In short · updated
A monthly retainer that keeps your product data complete and current in Google Merchant Center and ChatGPT Shopping. We fix titles, attributes, GTINs, variants, images, price and stock freshness, and return and support policies, so AI shopping agents can match your products to what shoppers ask. From $2,000 a month.

Who it’s for
A fit if
- You sell in the U.S., where ChatGPT Shopping is live, or want Google UCP checkout (U.S., Canada and Australia early access).
- Your catalog changes every week: prices, stock, variants, new products.
- You see Merchant Center disapprovals, missing GTINs or products shown with the wrong price.
Not a fit if
- You run a small catalog that rarely changes. The readiness audit will cover it.
- You’re on Shopify and only need the ChatGPT channel switched on. Shopify’s agentic channel largely covers that already (Alhena).

Why it matters now
ChatGPT Shopping accepts feed updates as often as every 15 minutes. Stale price or stock is a choice.

How we measure it
Each month we report feed errors, coverage of key attributes, price and stock mismatches, and Merchant Center performance. Where you also run AI visibility reporting, we track whether product-level prompts start citing or surfacing your products.
Price
From $2,000/monthTypical range $2,000–$6,000 per month
What moves the price: SKU count, number of feeds and countries, how often your catalog changes, and whether we have direct access to your feed tool or work through your team.

Questions about the product feed optimization retainer
What feed formats does ChatGPT Shopping accept?
Under the Agentic Commerce Protocol feed spec, merchants deliver feeds as TSV, CSV, XML or JSON, and updates are accepted as often as every 15 minutes.
Where do ChatGPT Shopping purchases happen?
On the merchant’s own site. Search Engine Land reports ChatGPT Shopping is live only in the U.S., and merchants apply at chatgpt.com/merchants. Optional feed fields include popularity, return rate and reviews.
What does Google UCP require?
UCP adds a checkout button inside AI Mode and Gemini while you remain merchant of record. Products need the native_commerce(checkout_eligibility) attribute plus return and support policies. Onboarding is early access in the U.S., Canada and Australia.
We’re on Shopify. Do we need this?
Shopify merchants are largely covered for ChatGPT through Shopify’s agentic channel. The retainer still matters if your data is the problem: weak titles, missing GTINs, wrong variants or stale stock travel through every channel.
Does this include Shopping ads?
No. A separate paid ads feed exists, but this retainer covers product data quality, not bidding or ad spend.
