Google's Merchant API migration is silently corrupting live prices — zeroed out, truncated to fractions of a cent, or multiplied by a million. No error. No dashboard warning. FeedWatchdog checks what Google is actually serving against your real prices, around the clock, and emails you the minute they diverge.
Start watching my feed How it works| Problem | Product | Your price | Google shows |
|---|---|---|---|
| ZERO PRICE | Linen Table Runner | $22.50 | $0.00 |
| MICROS TRUNCATION | Brass Bookend Set | $15.99 | $0.000015 |
| DOUBLE MULTIPLY | Ceramic Pour-Over Set | $48.00 | $48,000,000 |
Paste your product feed URL — the same XML, CSV, or TSV file you already give Google. No code, no tags on your site.
On every check, FeedWatchdog pulls the prices Google is actually showing shoppers and compares them against yours, product by product.
The moment a price zeroes out, truncates, or drifts, you get an alert naming the exact products — and an all-clear when it's fixed. No noise in between.
Google is forcing every merchant off the Content API by August 18. The replacement Merchant API has a documented price-corruption bug: prices pass validation, the dashboard shows green, and shoppers see $0.00 — or $48,000,000. Merchants only find out when revenue craters or Google suspends the listing.
Your feed tool won't catch it — the corruption happens after your feed is ingested. The only defense is checking what Google actually serves. That's the entire job of FeedWatchdog.
Every plan starts with a 14-day free trial. Cancel anytime — it's a toggle, not a phone call.
No. FeedWatchdog only needs your product feed URL — the file you already submit to Google Merchant Center. Setup is one form field.
Feed tools (DataFeedWatch, Feedonomics, etc.) validate what you send to Google. The Merchant API bug corrupts prices after ingestion — everything upstream looks perfect. FeedWatchdog audits the serving side, which is the only place the bug is visible.
Price integrity isn't a one-bug problem — feeds break on currency changes, sale-price logic, partial syncs, and future migrations. FeedWatchdog keeps watching for all of it.
The Starter plan needs no access at all. For Pro accounts we can optionally connect read-only to the Merchant API for deeper coverage — never write access.
