Private Click Measurements
Many privacy-conscious users may already know about the ways that Safari automatically blocks tracking. But Apple’s Safari white paper actually includes an interesting tidbit about a little-known mechanism called Private Click Measurement.
It essentially prevents cross-site tracking, but still enables advertisers to measure campaign effectiveness. It’s basically the best of both worlds, allowing websites to maintain revenue streams while protecting user privacy. It also appears to be an Apple proprietary system — and the company has even proposed it as a new standard for the whole World Wide Web.
