Stop letting Performance Max cannibalize your branded search traffic. Here is how to isolate brand search, apply conversion value adjustments, and target high-LTV purchasers.
Google Performance Max (PMax) is designed to maximize reported conversion numbers. By default, it will bid aggressively on your own brand name and existing customers, making the campaign look wildly profitable while generating zero incremental revenue.
Here is the exact framework we use to restore true attribution and scale Google Ads profitably.
1. Brand Exclusion Lists & Standard Search Isolation
Never run PMax without a Brand Exclusion List applied.
- Create a dedicated **Standard Search Branded Campaign** with exact match brand terms and manual CPC or Target Impression Share.
- Apply a **Brand Exclusion List** to your PMax campaign through Google Ads support or account-level brand settings.
- This forces PMax to find truly incremental new customers.
2. Asset Group Segmentation by Margin, Not Category
Most marketers group asset groups by product category (e.g., "Shoes", "Jackets"). We group them by **Gross Profit Margin Tier**:
- **Tier 1 (70%+ Margin):** Aggressive target ROAS (180%) allowing Google to bid higher for customer acquisition.
- **Tier 2 (40-60% Margin):** Moderate target ROAS (250%).
- **Tier 3 (Clearance / Low Margin):** High target ROAS (400%) or excluded from PMax entirely.
3. Conversion Value Rules for Customer Quality
Configure Conversion Value Rules in Google Ads:
- **Location Rules:** Increase conversion value by +20% for top-performing geographic tiers.
- **Audience Rules:** Increase value by +30% for high-intent CRM customer lists (repeat purchasers).
