It's interesting to see how many sites are setting analytics related ids and optimization/split testing cookies. I wasn't expecting that, since the dataset is purely the immediate response of the request to the root domain/homepage, and doesn't include any additional asset calls that would have occurred once the page rendered. Which indicates all of that analytics and testing infrastructure is integrated right smack-dab in the middle of the hot path of the server response. As an analytics guy, it'd be fascinating to get a peak behind the curtain at those architectures. Even more so if any of those implementations have gone through a CCPA/GDPR compliance review.
