Hi PH 👋 I'm Alex, solo founder from Berlin. Google Merchant Center only shows you disapprovals if you log in and look — and nobody logs in and looks. Products drop out of Shopping silently, and merchants find out from the revenue graph days later. So I built two things. This free checker: paste your feed URL, get a graded report of everything that would trip Google's format checks — GTIN checksums, price formats, broken images, duplicate IDs. No signup, no OAuth, nothing stored. Try the "broken sample feed" button to see a spectacular F grade. And FeedSiren itself (pre-launch): it watches your Merchant Center account continuously and sends one clean, batched alert when something new breaks. Monitoring only — it never edits your feed. Founding spots are open: $49 refundable deposit or a $390 first-year pre-order, both fully refundable until your monitoring goes live. Would love to hear what the checker finds in your feeds — and what it misses. I'm here all day.
