How does optimised targeting find new, high-performing audiences?

Optimized targeting expands reach by leveraging existing campaign targeting signals and the advertiser's first-party data. It then uses privacy-safe machine learning models to identify new, high-performing audiences that are likely to convert. This approach respects user privacy while enhancing campaign effectiveness. The other options are incorrect because optimized targeting does not primarily rely on landing page keyword analysis, manual changes to geo/language settings, or cross-account Customer Match data.
