If you're worried about being tracked it's a little too late.
Check out the lightbeam if you're using firefox.
https://addons.mozilla.org/en-US/firefox/addon/lightbeam/ this will show you what other web sites are accessed when you hit a page.
As an example when I refreshed the page RME sent info to viglink.com and google-analytics.com , both are used most likely for advertising. When I hit another page like KSL.com it shows I connect to 7 other 3rd party sites, and shows me that google-analytics.com is also one of them. So in theory, I they could be sharing some kind of data between them. If you want something frightening hit Dell.com and build out a server, they contacted 32 sites. This probably is why when you do a google search for something like shoes you will be visiting some other page and there will be an advertisement for the same shoes you were looking at 2 days ago. All this is happening outside of the law that is waiting on Trump's desk. From what I understand the bill just allows your ISP to watch you and attempt to make money off your habits if they weren't already. This all falls into the "Big Data" bucket where businesses are attempting to look into their crystal ball and determine what you're going to do next. If they think Kevin is going to be buying a ring and pinion from one of his recent posts maybe they have yukon gear as an advertiser and you'll start seeing advertisements and you're not quite sure why you're seeing them. A VPN won't do anything to prevent this, clearing cache, removing cookies, or using the incognito mode are ways around being tracked to a point. The VPN just prevents your ISP from getting the data not google-analytics or one of the other big advertising overlords, what keeps the VPN you selected from selling your information?
I use a smaller ISP so I'm not sure their capability of selling my data, it costs money to do the big data thing, I'm not sure smaller ISPs would be analyzing it themselves, I'd be more concerned about an entity like Google or the government
contacting my ISP and saying hey we want to stick an appliance that watched traffic and sent it off.
Sorry went off on a tangent, just because you're paranoid doesn't mean someone's not out to get you...
