The 80/20 Feed Fixes

Most feed issues come from 5 fields. Fix these and you’ll outperform 80% of competitors.

1. Title Structure

Format: [Brand] [Product Type] [Key Attribute] [Color/Size] [Model/SKU]. Put highest-search-volume terms first. Max 150 chars.

2. Custom Labels for Margin Tiers

custom_label_0: Margin tier (High/Med/Low). custom_label_1: Seasonality (Core/Seasonal/Clearance). custom_label_2: Product priority (Hero/Support/Test). Use these in Performance Max asset groups and Shopping campaign priorities.

3. GTINs & MPNs

Required for brand eligibility and comparison shopping. Submit via supplemental feed if not in primary catalog.

4. Image Quality

White background, product fills 75-90% of frame, no watermarks/promotional text. Test lifestyle vs. studio images — lifestyle often wins for apparel/home.

5. Negative Keywords

Weekly search term review. Add irrelevant terms as campaign-level negatives. Brand negatives in generic campaigns; generic negatives in brand campaigns.

Performance Max Asset Groups

Segment by custom_label_0 (margin tier). High-margin groups get aggressive ROAS targets; low-margin get volume targets. Feed audience signals from customer lists.
