A marketer advertises in many markets around the world, including Germany and France. They’ve started running YouTube and Search campaigns with Google, and they measure online conversions. What three things should this marketer know about the impact of regulatory changes on measurement and audiences for their business? Select three.

A marketer advertising across multiple global markets—including Germany and France—while running YouTube and Search campaigns and measuring online conversions should be aware of three impacts from regulatory changes: the quality of conversion modeling will be affected for existing modeled conversions on the Safari browser; cross-device and engaged-view conversions, along with YouTube campaign performance, may decline; and remarketing in DV360 and Google Display Ads will be impacted, with re-engagement supported through Privacy Sandbox integrations when Google tags are used.

• The quality of conversion modeling will be impacted across existing modeled conversions for the Safari browser.
• Cross-device and Engaged-view conversions will be impacted, and YouTube campaigns will begin to degrade.
• All remarketing capabilities for advertisers will be impacted and lost due to compliance with regulatory changes.
• Remarketing in DV360 and GDA will be impacted and integrated with the Privacy Sandbox for re-engagement when Google tags are used.
• All types of conversion measurement solutions will be impacted and lost because of regulatory changes.

Explanation:

The answer is largely correct and accurately reflects the expected effects of regulatory changes—such as the Digital Markets Act (DMA) in the EEA—and the ongoing phase-out of third-party cookies.

Impact on conversion modeling for Safari:
This point is valid. Browsers like Safari already restrict cross-site tracking through features such as Intelligent Tracking Prevention (ITP). While Google relies on modeling to compensate for missing signals, additional regulatory limitations can further reduce signal availability, which may affect the accuracy of existing modeled conversions.

Impact on cross-device, engaged-view conversions, and YouTube performance:
This is also correct. Cross-device conversions depend on identifiers that connect user activity across devices, which are increasingly restricted. Similarly, engaged-view conversions for video—especially on platforms like YouTube—rely on signals that are being reduced due to privacy changes and cookie deprecation. As data availability declines, measurement quality and campaign optimization effectiveness may gradually weaken.

Impact on remarketing in DV360 and Google Display Ads:
This statement is fully accurate. Remarketing is heavily dependent on third-party cookies, so it is directly affected by their deprecation. To address this, Google is introducing Privacy Sandbox solutions—such as the Protected Audience API—to enable privacy-safe re-engagement and interest-based advertising in DV360 and Google Display Ads when Google tags are in use.
