Shopping campaigns are only as good as your product feed. Small data quality issues silently waste budget through disapprovals, poor matching, and irrelevant impressions.
Top optimization tips
- Use clear, keyword-rich titles without keyword stuffing—brand + product type + key attribute
- Keep high-resolution images on white or lifestyle backgrounds; no promotional overlays
- Sync inventory and price daily to avoid disapprovals and angry clicks
- Customize labels for margin, seasonality, and bestsellers to segment bidding
- Split campaigns by product category for better bid control and reporting
- Fill all recommended attributes—color, size, material, GTIN where applicable
- Use supplemental feeds for local inventory or custom labels without overwriting primary data
- Map variant groups correctly so sizes and colors cluster properly
- Exclude out-of-stock or low-margin SKUs during peak periods strategically
- Localize titles and descriptions for international feeds
- Monitor disapproval reports daily during catalog changes
- Align sale_price and promotion timing with site merchandising
Search term hygiene
Review search term reports weekly and add negative keywords for irrelevant queries. Shopping captures broad intent—negative lists require ongoing maintenance.
