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.
What to do with this
- For B2B and services, start with Search only, Display and Pmax add noise before your Search is profitable
- Run Pmax only when your product feed is clean and conversion tracking is solid, garbage in guarantees garbage out on black-box algorithms
- Keep a Search brand-defense campaign live regardless of other campaigns, it's the cheapest ROI you'll ever run
- Use Display primarily for retargeting, not prospecting, cold Display traffic converts 3-5x worse than Search or Meta
- Evaluate each format's incremental contribution, if Display ROAS only looks good because it's taking credit for Search conversions, it's incremental zero
