Google this week launched the outcomes of testing carried out on its Privateness Sandbox APIs, providing a glimpse into how these new applied sciences would possibly form the way forward for digital promoting in a world with out third-party cookies, now through consumer selection. The experiments, carried out throughout the first quarter of 2024, aimed to judge the effectiveness of Privateness Sandbox APIs and different privacy-preserving alerts compared to third-party cookies for each publishers and advertisers.
The checks have been carried out throughout Google’s numerous promoting platforms, together with Google Advert Supervisor, Google AdSense, Google Advertisements, and Show & Video 360. The experiments have been designed to supply a complete view of how the brand new applied sciences would possibly influence each the provision and demand sides of the digital promoting ecosystem.
On the writer facet, the experiment was structured with three distinct arms. The primary arm, labeled “Management 1,” represented the established order with third-party cookies and different alerts equivalent to writer first-party information and identifiers current. The second arm, “Management 2,” eliminated third-party cookies however retained different alerts. The third arm, labeled “Therapy,” eliminated third-party cookies however enabled Privateness Sandbox APIs together with different privacy-centric options.
The outcomes from this publisher-focused experiment have been revealing. When third-party cookies have been eliminated with out enabling Privateness Sandbox APIs (Management 2 vs. Management 1), publishers skilled a big drop in programmatic income. Google Advert Supervisor publishers noticed a 34% lower, whereas Google AdSense publishers skilled a 21% decline. Nevertheless, when Privateness Sandbox APIs have been enabled (Therapy vs. Management 1), the influence was much less extreme. Google Advert Supervisor publishers noticed a 20% lower in programmatic income, whereas Google AdSense publishers skilled an 18% decline.
These findings recommend that the Privateness Sandbox APIs, when used at the side of different privacy-centric options like first-party information, will help mitigate the influence of third-party cookie loss.

On the advertiser facet, Google carried out experiments on a portion of show adverts visitors in Google Advertisements and Show & Video 360 between January and March 2024. The checks evaluated the effectiveness of measurement and viewers methods utilizing a mix of Privateness Sandbox APIs (Subjects API, Protected Viewers API, and Attribution Reporting API) and different privacy-preserving alerts.
The outcomes from these advertiser-focused experiments have been additionally promising. When it comes to scale preservation, which used advertiser spend as a proxy, Google Show Advertisements noticed an 89% restoration, whereas Show & Video 360 achieved an 86% restoration. For campaigns targeted on conversions, the return on funding (ROI) restoration, measured by conversions per greenback (CPD), was much more spectacular. Google Show Advertisements noticed a 97% restoration in CPD, whereas Show & Video 360 achieved a 95% restoration.
Remarketing campaigns, that are closely reliant on third-party cookies, confirmed decrease however nonetheless vital restoration charges. Throughout campaigns utilizing solely remarketing audiences, Google Advertisements noticed a 55% advertiser spend restoration, whereas Show & Video 360 achieved a 49% restoration.
