Google has published a new official help page introducing the Results tab in Google Ads Recommendations, allowing advertisers to measure the actual performance impact after applying certain recommendations.
The Results tab shows how campaigns performed one week after applying bid or budget changes and compares it to an estimate of what would have happened without the change. Reporting is based on a 7 day rolling average over a 28 day period, focusing on the primary bidding metric such as clicks, conversions, or conversion value.

The feature currently supports Budget and Target recommendations across Search, Shopping, Performance Max, and Demand Gen campaigns.
This update adds more transparency to automated recommendations and helps advertisers evaluate real incremental impact.
