What Are Internet Cookies and the Digital “Crumbs” You Leave Behind?

The Role of Cookies in Customizing Your Online Experience

When you visit a website, it may place a cookie on your computer. This cookie serves as a digital ID card, storing information about you such as your language preferences, items you’ve saved in your shopping cart, and the time of your last visit. This data allows the website to offer a more personalized experience the next time you visit. For example, if you’ve been browsing books on an online store, the next time you visit, you might see recommendations based on your previous activity.

How Cookies Work: A Simple Analogy

Imagine you’re Gretel from the fairy tale, surfing the internet. Each website you visit is like a new Lego house. Some houses have cookies, and others don’t. When a house does have a cookie, it places that cookie on your “surfboard,” or computer. This cookie not only stores information about you but also leaves digital “crumbs” as you navigate through the website. These crumbs help the website owner understand your behavior—did you visit the kitchen (perhaps the blog section) or the bedroom (maybe the contact page)? This information is invaluable for website owners looking to improve their services and offer a better customer experience.

First-Party vs. Third-Party Cookies

There are two main types of cookies: first-party and third-party. First-party cookies are set by the website you’re currently visiting. For instance, if you’re on Twitter, the cookie saved on your browser is a first-party cookie from Twitter. On the other hand, third-party cookies are set by a different website than the one you’re on. These are often tracking cookies used by advertisers to monitor your activity across various sites. For example, if you’re on and click a Facebook “Like” button, a third-party cookie from Facebook may be placed on your browser.

The Ethical and Privacy Concerns

Cookies are not without their controversies. In the early 2000s, Amazon used cookies to offer discounted prices to new users while keeping prices the same for returning customers. This practice of targeted discriminatory pricing has also been observed in the hotel and airline industries. As a result, some people opt to browse privately or clear their cookies when making certain purchases online.

What “Crumbs” Are You Leaving Behind?

You can manage your cookies by going into the privacy settings of your web browser and selecting “Delete Specific Cookies.” This will show you all the cookies stored on your computer, including those from websites you may never have visited. It’s a good practice to regularly check and manage these cookies to maintain your online privacy.

Final Thoughts

Cookies are an integral part of the modern internet, offering both benefits and drawbacks. While they enhance user experience by providing personalized content and recommendations, they also raise ethical and privacy concerns. Being aware of the cookies you collect and the digital “crumbs” you leave behind is the first step in taking control of your online footprint.
