At least 40% of consumers allowed iPhone apps to track them when presented with Apple’s new opt-in message, according to this AppsFlyer study of 13 million choices.

See this one, for example.

Bombora has launched Visitor Insights, a consent-based website tag that tracks the topics a device has consumed.   It infers intent, job function, management level, and other information that B2B publishers can use for ad targeting and personalization.  This Bombora report shows intent trends by industry: for example, media and advertising users show 70% more interest in Customer Data Platforms than they did last year.
