I think “privacy opsec” would be the right terminology, might help if you want to search for advice.

I have nothing specific to add, I just do the standard adblocker.

My personal op-spec mostly includes partitioning my personal life aside from my professional life. Like most people, I have a job that relies on privacy-invasive software, so I do my best to keep that separate and containerized away from my private stuff. This mostly means using different web browsers for different things (i.e. Librewolf for personal browsing and Brave for work-related internet). My job uses Gmail, but I personally use Proton. Depending on one’s needs and available resources, you could even have separate devices for these uses (work phone and personal phone, work computer and personal computer, etc).

Use separate accounts, Linux, adblockers. Don’t upload all your private data into the cloud. Don’t invite spying apps onto your phone. Don’t give identifying info like the phone number to every service…
