Autobidding needs a certain time to learn. This learning makes the system effective in aiming the goal set. There are performance fluctuations while learning.
Measure the performance a long time after the learning is over because the accuracy of optimization can keep growing.

The learning period takes place in the following cases in addition to the timing you set a new autobidding.

  • When you change the autobidding or conversion settings
  • When you add new campaigns, ad groups, or keywords

Autobidding signals
