Google Merchant Center: Supplemental Feeds & Promotions

Supplemental Feeds & Promotions

About This Service

Supplemental feeds let you enrich or override your primary feed without editing the source system, which is how you add custom labels, fix individual attribute issues, or run promotions without touching your ecommerce platform. System Strats uses supplemental feeds to solve data problems the primary feed cannot, without disrupting the main integration.

Our Process

1

Feed Audit

We review the full error, warning, and disapproval log, plus feed attribute coverage, and identify the issues with the biggest impact on visibility and revenue.

2

Remediation

We fix the root causes, whether that is missing attributes, price mismatches, policy issues, or platform integration problems, working through each systematically.

3

Optimization

We add custom labels, optimize titles and descriptions, set up supplemental feeds where needed, and integrate the feed with your Shopping campaign strategy.

4

Monitoring & Ongoing Management

We set up monitoring and feed rules so new issues get caught quickly, and stay involved for ongoing feed management as the catalog changes.

Why Choose System Strats

We work on Merchant Center alongside Google Ads every day, and we know exactly where the issues live on every major ecommerce platform. We are also honest about when a feed problem is really a product data problem in the source system, and we handle the full cleanup instead of layering workarounds on top of bad data.
