You check Merchant Center. No disapprovals. The feed says "active." Impressions look fine at the account level. So the catalog is healthy, right?
Not necessarily. There's a failure mode in apparel feeds that never trips a disapproval, never sends an alert, and never shows up as an error in your ads data. The products just quietly stop showing up the way they should — and the first signal you get is a slow bleed in impressions weeks later.
It comes down to how Google groups your variants.
Feed Forensics · Issue 01 walks through the exact diagnostic, the four checks that surface most grouping errors fast, and the validation approach that catches them before submission, so the fix is targeted instead of a full catalog reupload.
If you run apparel or any multi-variant catalog on Shopping or Pmax, it's worth knowing how many of your variants are serving disconnected right now.
