Feed Doctor finds why your products get disapproved in Google Merchant Center — and fixes the cause. One click scans your catalog against Google's disapproval reasons and returns per-product fixes in plain English: page-not-accessible, missing shipping weight, availability, and GTIN. Auto-apply the safe, deterministic fixes, or review the rest with a clear reason for each. Built with the German and Austrian market in mind, it reads only product and feed data — no customer information.

• One-click diagnosis of Google Merchant Center disapprovals
• Automatic, per-product fixes with plain-English reasons
• Weight, availability, GTIN & page-access repairs
