What Do You Overlook if You Use Just Client-Side Web-Analytics?

In the previous article comparing the JAMstack services of two popular providers, I have mentioned that one of my incentives of moving to Cloudflare was its basic server-side analytics provided even for the free tier users. Extended analytics is available on both Cloudflare and Netlify as a paid option: on Cloudflare you have to subscribe to one of the paid accounts (the cheapest is “Pro” plan that costs 20 US Dollars per month); on Netlify you can either subscribe to “Business” plan for 99 US Dollars per member per month, or you can enable this feature for every your site for just 9 US Dollars a month. If you need an accurate web analytics data, I definitely recommend you choosing one of these options because, as my analysis in this article shows, the client-side analytics solutions (e.g., Google Analytics, Yandex Metrica or Microsoft Clarity) overlook a large portion of visitors' interactions due to different anti-tracking solutions (e.g., personally I use uBlock Origin plugin for my web-browser). In this article, I show how much data you may overlook.
