Google: Search vs Display vs Performance Max
📖 3 min readUpdated 2026-04-19
Google Search, Display, and Performance Max are often confused. Each works for specific situations and fails in others.
Search
User types a query; your text ad appears. High intent, they're actively looking.
- Best for: direct response, lead gen, services, B2B
- Cost: higher CPC (competitive keywords hit $50-100+)
- Conversion rate: higher than other properties
Display
Banner ads on websites across the Google Display Network.
- Best for: retargeting, brand awareness, cheap reach
- Cost: very low CPMs ($1-5)
- Conversion rate: very low, usually just supports other channels
Performance Max (Pmax)
AI-driven campaign that runs across all Google inventory. You provide assets and conversion goals; the algorithm decides placements, audiences, creative combinations.
- Best for: e-commerce with product catalog, mature advertisers with good data
- Cost: variable, often competitive
- Conversion rate: depends on feed quality and creative
The decision
- Services / B2B / high-intent: Search only, at least initially
- E-commerce with catalog: Pmax + Search brand-defense
- Brand: Display + YouTube for reach
- Retargeting: Display works but Meta is often better
The Pmax warning
Performance Max is a black box. You lose granular control. Works when your product is clear and feed is good. Fails when your data is noisy or your product has complex positioning.
