What Is Feed Validation?
Feed validation checks your data feeds (product listings, RSS/Atom feeds, or XML data exports) against the receiving platform's specifications. A valid feed means your data gets accepted, processed, and displayed correctly.
For e-commerce, this is critical: an invalid Google Merchant Center feed means products don't show up in Shopping results or Performance Max campaigns.
Types of Feed Validation
Product Feed Validation (Google Merchant Center)
The most common SEO-adjacent use case. Google Merchant Center requires:
- Valid GTINs or unique product identifiers
- Correct pricing and currency formatting
- Accurate availability status
- High-quality image URLs that resolve
- Required attributes for each product category
RSS/Atom Feed Validation
Blog and content feeds need:
- Well-formed XML
- Required elements (title, link, description)
- Proper date formatting (RFC 822 for RSS, ISO 8601 for Atom)
- Valid character encoding
XML Sitemap Validation
While technically not a "feed," XML sitemaps follow similar validation rules:
- Valid XML structure
- URLs return 200 status codes
- Follows the Sitemaps protocol specification
- Under 50,000 URLs and 50MB per file
Common Validation Errors
| Error Type | Example | Impact |
|---|---|---|
| Missing required field | No price in product feed | Product disapproved |
| Invalid format | Date as "March 10" instead of ISO format | Feed rejected |
| Broken URLs | Image URL returns 404 | Product listing without image |
| Encoding issues | Special characters breaking XML | Entire feed fails to parse |
| Size limits exceeded | Feed over platform's limit | Partial processing |
Frequently Asked Questions
How often should I validate my product feed?
Before every feed update, and at minimum weekly if feeds are automated. Platform requirements change, and products get modified, both of which can introduce validation errors.
Can feed validation errors affect organic SEO?
Not directly. Feed validation primarily affects Shopping results and paid listings. However, XML sitemap validation errors can affect how Google discovers and indexes your pages.
What's the difference between feed validation and schema validation?
Feed validation checks data files submitted to platforms (product feeds, RSS). Schema validation checks structured data markup embedded in your HTML pages. Both ensure data correctness, but for different contexts.
