Same here, we’re about spend thousands of dollars on Google Shopping and Google is telling us that all of our products have an Invalid attribute value [image link]. We’ve haven’t touched the robots.txt so I don’t understand why we should be getting this error? Shopify needs to come up with a solution to quickly as it seems to be a native issue with the platform.
Topic summary
Users are encountering two distinct error types in the Google Merchant Center affecting product listings:
Image Link Errors:
- Products show “Invalid Attribute Value [image link]” in the Google app, though images display correctly on websites and in Google search results.
- Google requires specific image formats (JPEG, WebP, PNG, GIF, BMP, TIFF) and accessible URLs.
- Potential causes include robots.txt file blocking image directories or URL accessibility issues.
- This error may prevent products from appearing in Google Shopping.
- Status: No clear resolution provided in the thread.
Unit Pricing Measure Errors:
- Hundreds of products flagged with “Invalid whole number [unit pricing base measure]” and “Invalid real number [unit pricing measure]”.
- Google recently changed these previously optional fields to required.
- Working Solution: Create feed rules in Google Merchant Center:
- Navigate to Products > Feeds > Content API > Feed Rules
- Add rules for both unit_pricing_measure and unit_pricing_base_measure
- Set both values to “1ct” for items sold per unit
- Test changes before applying
- Users report that updating values directly in Shopify doesn’t resolve the error; changes must be made in Merchant Center via feed rules.
- Status: Resolved for users who implemented the feed rule solution.
