Apple Changes Business of Selling Your Browsing Data
Apple’s privacy enhancements to Safari squeeze out the small ad networks such as Criteo but make the Google/Facebook duopoly even stronger. Oops.
Online advertising is under siege from an unlikely coalition of privacy campaigners: Apple and European regulators. The only long-term solution may be for websites to be more explicit about how they make money from customer data.
Alphabet and Facebook FB -0.68% dominate this business, with 84% of all digital-ad spending outside China, according to WPP media agency GroupM. For them, however, the impact of the Safari update will be cushioned by their daily contact with consumers. Apple only blocks intermediaries from planting cookies; website owners like Google and Facebook can still use them to track users, including during a 24-hour period after they leave their sites.
