I personally don't post any kind of external advertisements in any of my websites: Not Adsense, not anything. I just don't charge other organizations and companies to advertise in my websites and I don't desire that this would happen. My websites are basically websites that give information and in which I present and offer my services.
I thus want to ask:
Does totally disabling cookie-gathering from my visitors, in my WordPress websites, might malfunction Google Analytics (if I'll decide to start using it in my websites sometime)?
The reason I'd like to totally disable cookie-gathering is to raise performance - I don't gather data on my visitors for external advertisements (that is, to better suit them advertisements).
I just want that basically any URL I serve under any domain, will be a cookie-free domain, to overcome Google PageSpeed Insights "Use cookie free domains" error.
But I do fear that if I do, it might prevent me from using Google Analytics, if and when I'll want to use it.
