Privacy Implications of Google Ads
Google Ads is classified as a high-risk advertising technology with a prevalence of 0.2% across our monitored dataset. When a website deploys Google Ads, it creates a data channel between the visitor's browser and googleadservices.com, allowing the collection of browsing behavior, page interactions, and potentially device fingerprinting data.
What Data Does Google Ads Collect?
As an advertising technology, Google Ads collects browsing data used for ad targeting and conversion tracking. This typically includes pages visited, purchase events, form submissions, and cross-site identifiers that enable user profiling across the 502 websites where it is deployed.
Compliance Considerations
Under GDPR and ePrivacy Directive, websites deploying Google Ads must obtain informed consent before the technology loads, unless it falls under the “strictly necessary” exemption. With a prevalence of 0.2%, Google Ads is one of the less common technologies in our dataset. Vendor risk teams should verify that partners using Google Ads have implemented proper consent management and data processing agreements.
