Optimizing your product feed for Performance Max campaigns

Performance Max campaigns use your product feed as the foundation for ads across Shopping, Search, Display, YouTube, Gmail, and Discover. The quality of your feed determines the quality of your ads and the efficiency of your spend. Bad feed data means bad ads, wasted budget, and poor ROAS.

Title optimization

Titles are the single highest-impact field in your feed. Put the most important attributes first because Shopping results truncate long titles.

Title formulas by category

Custom labels for campaign structure

Use custom_label_0 through custom_label_4 to segment products by business metrics. This lets you bid differently on high-value vs. low-value products.

Effective label strategies:

• Margin tier (high/medium/low) for bid optimization
• Seasonality (spring, summer, winter, year-round) for budget allocation
• Best-seller status (top 10%, regular, slow-mover) for bidding priority
• Promotional group (clearance, new arrival, evergreen) for messaging

Image selection for PMax

Performance Max shows your images across display and video placements, not just Shopping tiles. A white-background product shot works for Shopping but looks sterile in a display ad or YouTube card.

Use additional_image_link to provide lifestyle images alongside your standard product shots. This gives PMax creative variety for different placements.

Product type accuracy

Use your own product_type taxonomy in addition to google_product_category. This gives Google more signals for matching your products to relevant searches. Be specific. "Shoes > Running > Trail Running" beats "Shoes."

Feed freshness

Update your feed at least daily. Every 6 hours is better. Performance Max relies on accurate inventory and pricing. Stale data leads to disapprovals and wasted spend on out-of-stock items.
