Supplemental Feeds: Push Optimized Content to Any Platform
CSV, XML, JSON exports for Google Merchant Center, Shopify, and custom platforms. Supplemental feeds deliver optimized content without replacing your primary feed.
The Supplemental Feed Problem
You optimize your product content. Descriptions are rewritten. Titles improved. Specifications enriched. But your primary feed is managed by your product team. How do you get optimized content to shopping platforms without disrupting your workflow?
Supplemental feeds solve this. Export optimized content as a separate feed (CSV, XML, JSON) that you upload to Google Merchant Center, Facebook Catalog, or any platform. No disruption to your primary system.
Format Options
Google Merchant Center XML
Industry-standard format. Upload directly to GMC. Supports all ecommerce attributes. Regenerates on a schedule you set, or on demand.
CSV
Columnar format for custom systems. Flexible column selection. Good for manual review before uploading.
JSON
RESTful API format. Ideal for custom integrations or headless ecommerce platforms. Serves the most recently generated snapshot, so regenerate the feed (or let it regenerate on schedule) to pick up new changes.
Use Cases
Agency Content Delivery
Manage optimization for many clients. Each client downloads their supplemental feed and uploads to GMC. You deliver value without needing access to their primary systems.
Multi-Channel Seller
Sell on Shopify, Amazon, eBay. Push optimized titles and descriptions to Amazon and eBay via supplemental feeds without modifying your Shopify catalog.
Continuous Optimization
Run continuous optimization. Regenerate the supplemental feed on a schedule. Google Merchant Center merges it with your primary feed, so listings pick up approved changes without touching your inventory system.
Auto-Regeneration
- Scheduled: when auto-regeneration is on, the feed regenerates on the interval you set (daily by default)
- On-demand: manual trigger for latest snapshot
Real-World Impact
- Improved titles and descriptions can lift Google Shopping click-through; measure it against a holdout
- A cleaner feed means fewer Merchant Center issues to fix
- Agency clients can see the effect per client store in the same measurement view
Generate your first supplemental feed. Upload it to Google Merchant Center and start seeing improved listings.
