Asset Mix Cheat-Sheet
- Search Terms Insight report ➜ mine new negative keywords.
- Asset Group Performance ➜ create separate groups for personas (e.g., SME vs Enterprise).
- Audience Insights ➜ feed high-value segments back into other channels (Meta/LinkedIn).
- Geo & Hour-of-day ➜ layer bid-adjustment rules via Ad Schedule.
8. When NOT to Use PMax
- Hyper-niche B2B (<10 k TAM) where impressions are scarce.
- Products needing long-form education before a click (e.g., enterprise-security platforms).
- Regulated verticals with strict creative compliance (alcohol, pharma)—manual control is safer.
