Feed Forensics — Issue 03
Product Gaps
Google validates every product individually. Each failure pulls that SKU out of every campaign it belonged to — no email, no dashboard warning, no budget reallocation notice. The full picture lives in Merchant Center diagnostics, and in a typical apparel catalog it's worse than anyone assumes.

in a typical apparel catalog has at least one active disapproval — coverage gaps most brands have never counted
GoDataFeed audit data 2024–2025
Merchant Center validates each product separately, attribute by attribute. When one product fails, Google removes it from every campaign it belonged to and keeps serving the rest. No email goes out, no dashboard warning fires, and the account looks healthy. In a typical apparel catalog, 1 in 5 Shopping listings carries at least one active disapproval (GoDataFeed audit data, 2024–2025).
In campaign reports, a disapproved product looks the same as a product nobody searched for. Budget moves to the products still serving, so CPCs rise on what’s left. Competitors answer the queries your missing products should have won. Performance Max asset groups lose products without notice, and impression share drops with them. Sustained or policy-level violations can escalate from single items to account-level review and suspension, which affects the whole catalog.
The full count lives in Merchant Center under Products → Diagnostics, which lists every affected SKU and the reason behind it. Reading it after the fact is cleanup, because those products have already left the auction. Pre-submission validation checks product data against channel rules before the feed goes out, so the fix happens in the feed instead of after the campaign has lost coverage. The deck names the five causes behind most apparel disapprovals and shows which diagnostics numbers to read first.

FAQ
Merchant Center → Products → Diagnostics. Item-level issues list every affected SKU and the policy or data reason behind it.
Individually disapproved items exit campaigns; sustained or policy-level violations can escalate to account-level review and suspension, which affects everything.
Checking product data against channel rules before the feed transmits — so failures get fixed in the feed layer instead of surfacing as live coverage gaps.
