Several adtech companies have been in deep testing mode with Google's Privacy Sandbox for several months, since Chrome turned off third-party tracking cookies for 1% of its users. Criteo, a demand-side platform that helps advertisers place their ads, was also a Privacy Sandbox grant participant. Criteo forecast that if cookies were switched off now, publishers' Chrome ad revenue would decline by about 60% on average. AdvertisementStill, he added, the Privacy Sandbox already seems to be working better than a completely cookieless environment, "which is promising for an early-stage technology." To be sure, the Privacy Sandbox isn't the only alternative to the advertising ecosystem once cookies are discontinued.
