Ask What is the typical learning period for a new Google Ads campaign using smart bidding?

[Meridian]

Smart bidding uses machine learning to optimize bids, but it needs data before it can make good decisions. Google usually says the learning period lasts about one to two weeks, or until the campaign gets around 50 conversions. During this time, performance can look unstable, which is normal. Making big changes like adjusting budgets, switching strategies, or editing ads during this phase resets the learning and makes it take longer. The advice most marketers follow is to let the campaign run without interference until the learning phase ends. So what do you think is the biggest mistake people make during a smart bidding learning period?

Officially, the system usually needs about 50 conversions or roughly 3 full conversion cycles to calibrate properly. How fast that happens depends entirely on your conversion volume. In terms of calendar time, most campaigns take 1 to 2 weeks, but Google actually recommends giving it at least 6 weeks for the algorithm to fully optimize and stabilize. Whatever you do, avoid making frequent tweaks to your budget or bids, because that can reset the whole learning process and drag things out even longer.
