Change what Google sees without changing your store or your main feed.
You need one attribute corrected or a sale price added, but changing the source system is slow or risky. Your main feed integration works, and you’d rather not disturb it.
Supplemental feeds add to or override your primary feed without editing the source system. We use them to add custom labels, fix individual attribute issues and run promotions. They solve data problems the primary feed can’t, and your main integration stays as it is.

A multi-source feed setup for complex catalogs
We find what the primary feed can’t solve, such as attribute issues, missing custom labels or promotions.
We start with a Google Sheet for manual corrections or label tests, and move larger data to a proper feed source.
We match each row to your primary feed by item ID, so changes apply only to the items listed.
We manage sale prices and promotions through the supplemental feed and leave your ecommerce platform untouched.
We work on Merchant Center alongside Google Ads every day, and we know exactly where the issues live on every major ecommerce platform. A supplemental feed can hide a deeper problem, so we tell you when the fix belongs in your source data and handle that cleanup too.
It’s an extra data source that layers added or corrected data on top of your primary feed, matched by item ID. It’s Google’s official way to enrich a feed without rebuilding the source integration.
Whenever you need to fix attributes, add custom labels, manage promotions or override primary feed values without editing the source platform. They’re very common for larger catalogs.
Yes, and it’s often the fastest way to manage manual corrections or test custom labels. For larger or more dynamic data, we usually move to a proper feed source.
No. Supplemental feeds are processed alongside the primary feed, and they apply only to the items they reference.
