It's worse than this, actually. My advice is to download a script blocker like privacy badger as an add-on. Block everything, backing off to allow things only if you lose functionality on a site (usually things labeled "fonts" are perfectly safe, for instance, and you'll have to turn on calendar scripts to schedule ads, but you can turn them right back off) You'll see the invisible (has nothing to do with buttons or cookies) tracking scripts running on every site via privacy badger or noscript. They leave stuff on your computer's hard drive. To get rid of it, download Spybot Search and Destroy, free version, from CNet. (CNet, ironically, has 11 tracking scripts running) If you use your phone for browsing, there is no way to avoid being tracked as you browse, so the computer is safer. Twitter, facebook, many others are tracking you on most websites. Not here, not wikipedia, but a lot of places. I just checked at bookbub's author signin--there are five scripts running. A major newspaper, randomly chosen, 11 tracking scripts. That's how magazines and newspapers make their money these days.
Further advice: never hand over your mailing list to anyone, no matter if they swear it will improve ad performance or not. They are lying, and they are using it for bad purposes. (Consider it a sacred trust between you and your readers, rather than a way to line some billionaire's pockets even more.)
Google's tracking is hard to avoid without reverting to land lines and snail mail, and apple impossible if you own apple devices. They're tracking you all the time, and the tracking rate increased with the new gmail version. Worse, Google (or Apple, or both) knows exactly where you shop if you carry your phone, how long you shop there, and if they wanted, they could pay for the overhead security camera footage from every store and assuming you buy via credit card, your purchases. (they don't care, but they could, and at that point that all checkouts are automatic (they "read" the codes off your purchases and "read" your credit card as you walk through a gate), privacy will be entirely dead. Enjoy what's left while we have it, is my attitude! (though I block scripts and never carry a phone with me.)
eta: privacy fiends are so upset about Google's changes that they're looking into other options for mail. Some are listed here:

Or there was, when the internet was new, but those days are long gone and VS's eating up boards like writers' forums to monetize them differently is just one head of a Hydra that gets more monstrous with every passing week.
