Google’s help page for bid strategy learning periods has been updated. The learning period now states that calibration can take up to around 50 conversion events or 3 conversion cycles, replacing the previous duration of up to 3 weeks or 1–2 cycles.
This volume-based benchmark is crucial for low-volume accounts. Additionally, Performance Max campaigns are now included in the conversion goals best practices documentation. These changes affect how advertisers manage and optimize their campaigns using Smart Bidding strategies.
