Start with the exact issue and affected products
Do not begin with a broad catalog rewrite. Start by grouping disapproved products by issue code, affected destination, and the number of offers involved.
That gives you a smaller working set and helps you distinguish one broken template from a catalog-wide problem.
- Export or review the exact issue text from Merchant Center
- Sort products by the dominant error pattern
- Flag high-volume issues before one-off edge cases
