Product Optimization: baseline vs. proposed attribute diffs, with GMC and GMfC submission

​
Overview

Product Optimization rewrites your product data (titles, descriptions, and attributes) to be clearer and more complete for AI shopping engines, then submits the results to Google Merchant Center and Google Manufacturer Center. Better structured data is one of the most direct levers for getting onto the shelf.

​
Choosing products

The candidates list shows your tracked products with a readiness score and the number of suggested improvements. Readiness reflects how complete your product data is. Start with high-impact, lower-readiness products.

In guided mode the job pauses for your review; in auto mode it runs straight through to await your approval.

​
Reviewing changes

The workspace shows your product with baseline vs. proposed attribute rows. Accept or reject changes, rewrite individual attributes, or refine by chat. Separate tabs organize the data for Review, Google Merchant Center, and Google Manufacturer Center.

​
Submitting

When you Approve a job, submission unlocks:
  • Submit to GMC: preview the feed snippet with a dry run, then submit. Apply changes to one variant or bulk-apply across several.
  • Publish to GMfC: for products whose brand is approved in Manufacturer Center.
Every submission is versioned. Use the version timeline to review past submissions or roll back.
Hard policy violations (prohibited claims, length limits) block submission until resolved. Advisory issues appear as warnings you can choose to proceed past.
