If you are going to run a privacy focused site, like for people into Monero, there are some things to avoid.
The first is the use of 3rd party trackers like Google Analytics. Don't use these since it's sharing data with Google and its adnetwork.
Similar to no 3rd party trackers is no 3rd party scripts or resources. If a site is loading CSS and JS files from a Google domain, or any other domain, that is a red flag. That is a way of tracking the use of that site. Avoid doing any of this and load all files from your own domain.
Ideally do not use JavaScript but this is often impractical. Have a no JS version if possible.
