The identifier in server logs is IP address, which is useless for distinguishing users. On the corporate side, NAT hides all the visits of many people behind a single IP. On the consumer side, ISPs change IP addresses all the time so a single person will show up as multiple IP addresses.

Note that I'm just talking about distinguishing people, not identifying or tracking. A basic question like "how many people came to my website today" is more accurately answered with client-side analytics than by analyzing web server logs.

How can client side analytics be more accurate, when ad blockers stop visits from even being registered by client-side analytics?

Before looking at accuracy, you already have compliance challenges with logging IPs / user agents and using it for analytics purposes.

Please don't try and change the goal posts. You said:

> Server side logs aren’t an accurate way of doing analytics...

What is your thinking behind that statement, as it sounds incorrect?

What compliance is challenged by logging user agents?
