Decision rule

Match the campaign type to your weakest constraint: query control, feed quality, conversion volume, creative assets, or measurement reliability.

How to compare

Use the comparison as a decision frame, then verify it with your store data.

  • Search is best for explicit query intent and controlled tests.
  • Shopping is best when product data is clean and demand is product-led.
  • PMax needs guardrails because automation can hide channel and query mix.

Common mistake

Launching PMax before fixing the feed and purchase tracking makes automation learn from weak signals.
