Google has made numerous changes to its help document on Google Ads conversion measurements. The updates include information about data collection timing and sources for gathering data, enhancing advertisers’ ability to optimize their campaigns.

Among the key updates are details on the 7-14 day learning phase required for Smart Bidding strategies, and data source preferences that can be saved for future use in conversion setups. Additionally, adjustments must be carefully managed to avoid resetting the learning window, and linking accounts may take up to 48 hours before import options appear in Google Ads.
