Tracking visitors on PBN ? without leaving footprints ?

Hello, I would like to track visitors on my PBN network, I got more than 40 real websites, but the problem is if I will install the same analytics script on each of website I will leave huge footprint, I'm not talking about google analytics I would like to use selfhosted solution like fathom, do you have any idea how to track visitors on my PBN without leaving footprint ?

If you have cpanel then awstats gives your detailed analysis, though its raw data, i suppose for PBN that is a fair amount of data provided. It doesnt leave any trace other than those cpanel related footprints which i assume have been covered considering you would have used different cpanel account for each of your PBN

thanks, but It will be hard task to login on each different CPANEL everyday to check stats ..better to have all data on one panel.. there is some solution like this one matomo proxy

"github.com/matomo-org/tracker-proxy" -- "This script allows to track websites with Matomo without revealing the Matomo server URL."

but for 40 websites, matomo/piwiq require alot of resources on server, and I no need detailed stats like it is in matomo

I would like to use something like above but with Fathom Analytics - fathom is lightweight compared to matomo/piwik , so for PBN it would be great to use Fathom.

I use Matomo (Piwik) for this task on powerful server intel xeon 64gb. This is yhe best practice, i think.
