How To Fix GMC Mismatched Product Availability
Why You’re Seeing This Disapproval in Google Merchant Center?
If you’re seeing “Mismatched Product Availability” errors in Google Merchant Center, you’re not alone — and yes, it will be hurting your Shopping performance.
This happens when your product landing page availability doesn’t match what’s in your product feed. Google flags this as a reliability issue, which can quickly lead to disapprovals.
To protect users, Google cross-checks your product feed against your landing page and structured data (schema markup). If any of these signals conflict, your products may be pulled from Shopping ads and free listings, even if they’re actually in stock.
Where to Find Mismatched Product Availability
You can check for this issue in Google Merchant Center by:
Navigating to Products → All Products
Clicking on the Needs attention tab
Looking for “Mismatched value [availability]”
Common Causes of Mismatched Product Availability
Mismatches happen more often than you’d expect, especially if your feed and website don’t update at the same pace. The most common culprits are:
Inconsistent feed and landing page content: Feed says “in stock,” but the website shows “out of stock.”
Structured data conflicts: Schema markup shows different availability than your feed or live page.
Shared URLs for product variants: A single URL for multiple variants (e.g. size, colour) confuses Google if one is out of stock.
Caching delays or slow updates: Page caching prevents real-time updates from showing when Google crawls.
Google crawl errors: Data looks correct, but Googlebot retrieves outdated or missing signals.
How to Fix Mismatched Product Availability
1. Align Product Feed To Landing Page
Update your feed regularly to reflect live stock levels.
Sync your inventory management system directly with your feed.
2. Check Your Data
Use Google’s Rich Results Test to check what structured data Google sees.
Ensure schema availability matches both the feed and live product page.
Example: product ID: XYZ
Feed: Availability - In Stock
Landing Page: Availability - In Stock
Structured Data: Out of Stock → ❌ Disapproval triggered
3. Use Unique URLs for Product Variants
Assign a dedicated URL to each variant (e.g. colour, size).
Avoid shared URLs when variants have different availability.
4. Reduce Caching Delays
Configure your site to update product availability as frequently as possible.
Avoid long cache expiration times on product pages.
5. Handle Crawl Issues
If all looks correct but errors remain, request a manual review in GMC:
Go to Needs attention, select the affected product, and click Disagree with decision.
Reviews typically resolve within 24 hours.
Pro tip: If your stock changes frequently, enable Automatic Item Updates in GMC. Google can use structured data to correct availability automatically and prevent disapprovals.
