When using Ads Personalization, what happens to the data from excluded events?

The correct answer highlights that when events are excluded from Ads Personalization, they are still utilized for measurement purposes. This means that while the specific events are not leveraged for creating personalized ads, their data remains within the system and can be used to analyze overall performance and effectiveness of campaigns.

Excluding certain events from personalization allows advertisers to retain valuable information without using it for ad targeting, which helps maintain compliance with privacy regulations and user preferences. Therefore, the data from those excluded events provide insights into user behaviors and interactions that can inform future strategies, ensuring that marketers can still gauge the performance of their ads without compromising user experience or privacy.

The other options misrepresent the handling of excluded event data. Deleting data would eliminate any chance of analysis, while retaining it for future analysis suggests it would inform ad targeting, which contradicts the purpose of exclusion. Additionally, making this data visible to all users misrepresents data privacy principles, as excluded events are meant to be kept confidential for targeted advertising purposes.
