Understand what this lesson solves

Basic full lesson

Not every Merchant Center notice means the same thing. Sort issues into fix now, observe, or non-blocking first, then check the feed, GTIN, price, availability, and product status.

Verify your account, product data, and conversion signals, then choose Search, Shopping, or PMax and run your first controlled optimization cycle.

Lesson outline

  1. 1Choose the validation sample by catalog size
  2. 2Open Merchant Center issues and data-source paths
  3. 3Align the feed row, Shopify, product page, checkout, and structured data
  4. 4Validate GTIN with real evidence
  5. 5Classify issues as fix first, observe, or not blocking this release
  6. 6Write the field-change record
  7. 7Observe 3-7 days before Shopping / PMax release

Public core framework

  • Sampling is not a fixed 10-SKU rule. For a tiny catalog, review every SKU first. For a mid-size catalog, sample priority SKUs, ad SKUs, problem SKUs, and markets.
  • Use Products, Needs attention, issue detail, and Data Sources processing to record the issue, affected item id, source, processing state, and last update time. UI labels may change;
