  > Referer includes the site you came from, what am I missing? I never claimed otherwise? There are two separate metrics in question here. One is the "visit" metric which the post specifies is based on the referrer. The other is quantifying which other sites sent traffic your way. The post conspicuously fails to define how that second metric is computed. For that second metric, I noted that there is an obvious incentive to avoid using the referrer and that the current status quo is to rely on other methods. (In particular, fingerprinting combined with centralized analytics services that have vision into a vast amount of traffic. Note that Cloudflare easily qualifies here given the sheer number of assets and websites they host.) If the entirety of this analytics service is based solely on referrers coupled with IP addresses then the author should unambiguously state that up front. Otherwise I'm going to assume the worst for the reasons given above.
