Google, Facebook and who knows what other ad-driven Internet sites are by design, attempting to track you in all kinds of pervasive ways in order to show you ads. This is their nature, it's their business, and I'm going to outline a simple technique that will reduce some of your exposure.
Google and Facebook have extensive tracking networks. When you login to their services, they can tie all kinds of off-site browser activities to your ID.

You can do this by simply running two browsers. I chose Google Chrome and Firefox, but any two will do.
In one browser (Google Chrome in my case), I do only the following activities:
In my other browser, I do:

Although I've ran with the above configuration for about a year or two, I've recently started experiment with other browser pairs, such as:
