Shopping is won in the feed, not the campaign
Performance Max and Shopping campaigns are distribution layers on top of one asset: your product feed. When products underperform, the instinct is to adjust bids - but the leverage is in the feed. Titles, images and attributes decide both whether you show and how well you convert when you do.
The 2026 feed checklist
Titles: brand + product type + key attribute + size/variant, in that order - the format Google's matching rewards. Images: white or lifestyle backgrounds, the primary image matching the search intent, and rich-image enhancements (swatches, badges, AR) enabled. GTINs and identifiers: complete, accurate, non-negotiable for ranking. Availability and price: real-time sync, because disapprovals are silent sales losses. Product types: custom taxonomy that mirrors your site structure for reporting clarity.
The monthly feed rhythm
Feed audits monthly: approval rates, data quality scores and competitor pricing for your top 20 SKUs. Enhanced-feature adoption quarterly. The measurable payoff: our feed overhauls routinely lift Shopping CTR 25-40% and reduce disapprovals to zero - before a single bid is touched.
