What Are Cookies?

You see cookies are text files that websites store in your web browser to remember your settings and preferences based on the data from the last session. Let’s say you logged into that site last time, so the next time you visit it, you will stay logged in. It also helps to remember the visited pages, items you liked, selected language, and more.

This gives you a clear idea that cookies are important but not all cookies are the same. You can classify cookies into two types, First-party cookies, and third-party cookies. And the latter will be the focus of this article.

What are Tracking Cookies?

First-party cookies are cookies created by a website and can only access data on that website alone. Even though they are still stored on your browser, these cookies will not be able to track your activity outside of that website.

On the other hand, third-party cookies can track you outside of the website they are created in. This is why they are also called tracking cookies. They are used primarily used for retargeting and personalized recommendations.

Retargeting is a way to show you ads for a product that you previously browsed on another website to sell that product to you. Let’s see how third-party cookies retarget ads on other websites that you visit.

  • When you browse a shopping site, it saves a tracking cookie in your browser with a unique ID.
  • That shopping website has signed up with an online advertising platform like Google to show its ads.
  • You visit another website that shows ads from Google to earn revenue.
  • The website will pick up the cookie stored in your browser and send it to Google.
  • Google will identify the unique ID from the cookies and trace it back to the shopping site.
  • The shopping site will then suggest items to show you as ads on other websites.

Tracking cookies can also accumulate a lot of data about the device you use, search queries, previously visited websites, how long you spent on those sites, the content you prefer, and create a personality that can be used by other advertisers signed up with Google ad network.

So finally the question comes down to, what exactly can you do about these tracking cookies and how can you protect your data from being tracked any further? We have listed down three ways that you can use to clear all cookies and spoof their data so it does not track back to you.
