How long does it take for Smart Bidding to optimize campaigns effectively?
Smart Bidding requires a learning phase to optimize campaigns effectively. Typically, it takes 1–2 weeks or about 50–100 conversions for Google’s AI to gather enough data and make accurate predictions. During this period, bid adjustments may fluctuate as the system learns which clicks are most likely to lead to valuable actions.

Additionally, not aligning bidding strategies with campaign goals or failing to combine human insights with AI automation may limit potential ROI. Avoiding these mistakes ensures smoother campaigns, better conversion optimization, and more efficient PPC marketing outcomes.
Key mistakes to avoid:
