Why mismatches are punished hardest
Most data errors cost one product its listing. Price and availability mismatches trigger preemptive item disapproval: Google errs on the side of caution and disapproves items likely to mislead, and clearing them needs an account review, not just a data fix. The logic is shopper-first: a wrong price at checkout is the fastest way to destroy trust in Shopping results, so the enforcement is deliberately unforgiving.
Price mismatch patterns
| Pattern | Typical cause | Fix |
|---|---|---|
| Off by cents | Multi-currency rounding between Shopify and the feed | Round consistently on one side; verify in the feed currency |
| Sale ended, price did not | Promotion expired overnight; feed re-fetches later | End the sale price and the promotion together; shorten feed refresh intervals |
| Different currency | Feed currency differs from page currency | One currency per target country feed; never mix |
| App-discounted price | Discount app changes page price post-feed | Ensure the feed reads the final presented price |
Availability mismatch patterns
The classic is Shopify “continue selling when out of stock”: the page stays purchasable while the feed says out of stock, or the reverse after a restock the feed has not picked up. Fast-moving inventory during sales makes this chronic: the store shows in stock, Merchant Center still shows the old status, and Google flags it as inaccurate rather than outdated. Timing issue, same punishment.
Keeping feed and page in sync
- Feed refresh runs at least daily: hourly during sales
- Sale start and end dates exist in both Shopify and the feed
- One currency per country feed; no mixed-currency targets
- “Continue selling” products carry availability logic you can explain
- Landing page price verified against the feed after every price change
