I'm thinking about how to manage best practice consent with web analytics. This is specifically for sites without hardcore data-driven conversion optimisation, etc., where absolute accuracy is not crucial.My assumptions are that:- client-side will under report, because  users opt out or block JS and cookies- server-side will over report, because of bots, crawlers, etc.I was thinking that combining both in a dashboard can give clients a sense that the reality will be somewhere in the middle. Obviously there's a limit to how many metrics can be measured by both systems to enable this comparison, but I'm thinking the basics should be possible. Are my assumptions about over- and under-reporting right?Does anyone do anything like this and how do you do it?And are there any metrics that help us understand how much traffic is being missed by, for example, Google Analytics these days? Many clients still assume that it gives a 100% gospel representation.
