It's much ado about nothing, just make sure you make it hard for them,
one step is replacing your DNS servers from the default your ISP assigns,
"if they let you change it" mine does so I use AdGuards DNS servers.
I am not saying this will stop all or that this is all you need to do, but
it is a big step in the right direction
Step 1> Change your DNS to Adguard or another secure 3rd party.
Step 2> Use a homepage and search engine that will not track you
or collect info, I use the Duck.
Other steps include cleaning your browser regularly, set it to clean at closing,
I do this and have Ccleaner clean it too at closing, just to make sure.
