How does Google model conversions when there's no shared identifier between ad interactions and conversions or when conversions can’t be measured?
We separate ad interactions based on whether we were able to observe the link between that ad and the conversion.
Then, we identify a group of similar-behaving users in the observable group and calculate their conversion rates. We also analyse other factors, including device type, time of day and operating system, in order to assess similarity.
We train our machine learning model to determine the likelihood of conversions across all users that interacted with the ad, even those that weren’t directly viewed because of browser or OS restrictions. We apply these training techniques uniquely for each advertiser’s specific business needs.
Then, we validate that our models are representative by leveraging data from other calibration signals, such as historical conversion trends. Learn more About modelled online conversions

How do these new measurement solutions for iOS affect my bidding?
Our bidding systems rely on the measurement solutions used to collect data such as the Google tag (gtag.js), Google Tag Manager (gtm.js), and Google Analytics for Firebase. As we develop new measurement solutions like conversion modelling and new URL parameters, we closely monitor their effect on our bidding systems and make adjustments accordingly.
Campaigns using Smart Bidding will continue to set bids based on the most accurate measurement available. However, we recommend that you prepare for the above changes by closely monitoring the performance and delivery of all campaigns serving on iOS traffic. If necessary, you can also make adjustments to budgets and Smart Bidding CPA or ROAS targets to help you achieve your goals. For example, if you'd like to increase spend, you can raise CPA targets or lower ROAS targets as needed.If you’re running App campaigns with the Target ROAS bidding strategy, you should switch to Target CPA right away.
