This way websites track you. Tracking is generally used by advertising networks to build up detailed profiles for pinpoint ad-targeting even tracking down users for special purpose such as effecting their political choices. Recall the data tracking reported in US elections, Brazil elections and many more. The type of information available through your web usage patterns, which websites generally use for tracking you, are :

(a) IP Address

IP address is a unique address of your device when you connect to the Internet. It's likely that your computer shares your IP address with the other networked devices in your house or office. From your IP address, a website can determine your rough geographical location.

(b) Cookies and Tracking Scripts

Cookies are small pieces of information websites can store in your browser. They have plenty of legitimate uses – for example, when you sign into your online-banking website, a cookie remembers your login information.

(ii) Third party cookies. These are the cookies that websites store to know about your search history and web browsing history so as to place advertisements as per your interests. Third party cookies may result in many unwanted advertisements on your web pages.

(c) HTTP Referrer

When you click a link, your browser loads the web page linked to it and tells the website where you came from. For example, if you clicked a link to an outside website on a web page, if you click at the link shown then the linked website will get opened and internally information about you such as your IP address,location, your web browser, machine type etc. will also be provided to the linked website – the HTTP referrer.

(d) Super Cookies

Super cookies are also cookies but these are persistent cookies, i.e., they come back even after you delete them. Super cookies (like evercookie) store cookie data in multiple places – for example, in Flash cookies, Silverlight storage, your browsing history, and HTML5 local storage etc. When a website notices that you've deleted part of the super cookie, the information is repopulated from the other location. For example, you might clear your browser cookies and not your Flash cookies, so the website will copy the value of the Flash cookie to your browser cookies.

(e) User Agent  

Your browser also sends a user agent every time you connect to a website. This tells websites your browser and operating system, providing another piece of data that can be stored and used to target ads. All the above things leak your identity information to websites and it may be used against you. Solution to this is Private browsing and Anonymous browsing. let us learn what is this type of browsing
