How Each Campaign Works
Standard Shopping
You upload a product feed to Google Merchant Center. Google matches your products to relevant search queries and shows product listing ads (PLAs) on Search and the Shopping tab.
You control:
• Which products are in the campaign
• Product group bids (manual or automated)
• Negative keywords
• Device, location, and schedule bid adjustments
• Search terms visibility (full search terms report)
Google controls:
• Which search queries match your products (based on your feed)
• Ad placement within the Shopping carousel
Performance Max
You provide a product feed, text/image/video assets, and audience signals. Google's AI runs your ads across ALL Google surfaces — Search, Shopping, Display, YouTube, Gmail, Maps, and Discover.
You control:
• Product feed and asset groups
• Budget and target ROAS/CPA
• Audience signals (suggestions to the AI, not hard targeting)
• Location and language targeting
Google controls:
• Which searches trigger your ads
• Which channels and placements are used
• Bidding (fully automated)
• Ad creative assembly
• Audience targeting (with your signals as guidance)

The Case for Standard Shopping
When Standard Shopping Wins
1. You need granular control.
Standard Shopping lets you see exactly which search queries trigger your products, set bids per product group, and add negative keywords. For advertisers who want to optimize at the keyword and product level, nothing matches this control.
2. You have a small catalog.
With 50-200 products, manual product group management is feasible and effective. You can set specific bids based on each product's margin and performance.
3. You need full search term data.
Knowing exactly which queries trigger your products is essential for keyword optimization, negative keyword management, and understanding customer search behavior. PMax provides minimal search term data.
4. You want to control brand vs non-brand.
Standard Shopping lets you create separate campaigns for branded and non-branded traffic using negative keywords. PMax handles this internally without transparency.
5. You're spending less than $5,000/month.
Smaller budgets benefit from the tight control of Standard Shopping. PMax needs budget to test across multiple channels, which can dilute a small budget.
Standard Shopping Best Practices
• Segment by margin: High-margin products get higher bids, low-margin products get lower bids
• Use custom labels: Segment by performance tier (best sellers, regular, clearance)
• Priority campaigns: Run multiple campaigns at different priorities for bid control
• Weekly search term reviews: Add negative keywords consistently
• Start with Manual CPC or Maximize Conversion Value, then move to Target ROAS

The Case for Performance Max
When Performance Max Wins
1. You have a large catalog (500+ products).
Managing thousands of products across product groups in Standard Shopping is impractical. PMax's AI handles catalog-wide optimization automatically.
2. You want multi-channel coverage.
PMax runs ads across Search, Shopping, Display, YouTube, Gmail, Maps, and Discover from a single campaign. For brands that want presence everywhere Google reaches, PMax is the most efficient way.
3. You have strong conversion data (30+ monthly conversions).
PMax's AI performs best with abundant conversion data. More data = better optimization = higher ROAS.
4. You want to reach new audiences.
PMax's audience expansion capabilities discover customer segments you might never find with Standard Shopping's limited targeting. The AI finds converting users across all Google properties.
5. You have creative assets beyond product images.
