Seeing "Automatic updates: Mismatched availability" or "Automatic updates: Mismatched condition" in Google Merchant Center means Google changed your product data to match your website. That is automatic item updates at work. This guide explains what the feature does, why the messages appear and how to stop the mismatches behind them.
What automatic item updates do
Google reads the structured data and other product details on your pages and compares them with the data you sent. If they differ, it can update the product in your Shopping ads and free listings. Google's example: if your data says $4 but the page says $3, it updates the product to $3.
- Attributes covered: Price, sale price, availability and condition
- Default: Google says automations are enabled by default
- Where: Products, then the Automations tab, then View details on each automation
What the messages mean
The messages are a record that a fix happened, not a disapproval. "Automatic updates: Mismatched availability" means the stock status you sent differed from your site and Google updated it. "Automatic updates: Mismatched condition" means the condition you sent conflicted with your other product details, so Google changed it.
| Message | What Google did |
|---|---|
| Mismatched availability | Changed availability to match the site |
| Mismatched condition | Changed condition to match the other attributes |
Why mismatches happen
Google's help pages point to timing. When your site changes at a different time from your product data, the two drift apart. Google also lists limits on how far the feature can help.
- Frequent changes: Products whose price or availability changes more than once a day may be disapproved instead of updated
- Too many mismatches: Google says it may stop updates if the total gets too large
- Multiple strikethrough prices: Google says not to turn on price updates if pages show more than one
- Local data: Local product or inventory sources can also carry the wrong availability
Find and fix the affected products
In Merchant Center, open Products, go to the Needs attention tab and filter by the message. For one product, choose Edit product, correct the value so it matches the page and save. For many, download the .csv list, compare it with your data and fix the source.
On Shopify, the Google & YouTube channel syncs products from your store, so the fix usually belongs in Shopify: correct stock, price or condition there and let the channel sync it.
Keep it as a safety net
Google says automations do not replace regular product data updates. They fix occasional mismatches. The lasting fix is updating your data as soon as your website changes.
- ✅ Schema.org markup for price, currency, availability and condition on product pages
- ✅ Product data updates scheduled straight after website updates
- ❌ Relying on automations to fix a feed that is always out of date
For the page crawl versions of these issues, see the price mismatch guide and the availability mismatch guide.
Doing this at scale
FeedFix checks every product against Google Merchant Center and Meta Catalog rules and scores each one from 0 to 100 per channel, so you can see which products have data problems. It drafts compliant title and description rewrites you review as before/after diffs, apply in bulk, and every change is audit-logged. See FeedFix.
