Smart Bidding vs Manual: The Real Guide


The question comes up with every client: should I let Google's AI manage my bids, or keep control?


The answer is nuanced and depends on 3 key factors: your data, your volume, and your goals.


When to Use Manual Bidding (Max CPC)


  • New campaign with < 30 conversions/month
  • Very limited budget (< €500/month)
  • Highly seasonal sectors
  • Brand keywords
  • Testing new markets

  • When to Use Smart Bidding


  • **Maximize Conversions**: Ideal at launch
  • **Target CPA**: Ideal when you have > 50 conv/month
  • **Target ROAS**: For e-commerce with variable basket values
