What is Smart Bidding?

Smart Bidding uses machine learning to optimize bids in real-time, considering hundreds of signals: device, location, time, browser, and more.

Smart Bidding Strategies

  • Target CPA: Optimizes for a desired cost per acquisition
  • Target ROAS: Optimizes for a desired return on ad spend
  • Maximize Conversions: Gets the most conversions for your budget
  • Maximize Conversion Value: Maximizes total conversion value

Requirements

Needs at least 30 conversions in the last 30 days. Learning phase takes 1-2 weeks. Don't change settings during this time.

Pro Tip: Start with "Maximize Conversions", then switch to Target CPA once you have 50+ conversions/month.
