On June 30, 2025 we announced that we would roll out a change that would cause our bidding models to start using the presence of the ClickConversion.conversion_environment
That change, which may have caused performance degradation in certain campaigns where this is not set, will no longer be implemented. However we still recommend that users who import conversions using the Google Ads API set the conversion_environment
Accurate cross-environment attribution: Understand the full value of your campaigns across website and app sources.
Ad destination reporting : Gain insights into where the user lands after clicking your ad, and the relative performance of each segment.
Streamlined Google support: Receive faster and more effective troubleshooting.
For more details see this Help Center article .
If you have any questions or need help, see the Google Ads API support page for options.
