Websites: They’re maintaining your logged in state, saving your preferences and showing you content that feels personalized. You could argue that cookies make that convenience even easier.
What are cookies Cookies are small text files that are placed in your browser by the websites you visit. Invisible to most users, cookies are integral to how the modern web works.
And yet cookies are frequently the subject of privacy concerns and tracking fears. A lot of people stare at cookie consent banners and don’t actually understand what they are consenting to.
This comprehensive guide discusses cookies in great depth, how they operate on the web, what their purpose is, the different types of cookies there are and no less importantly why it’s important to use them responsibly as users and website owners.
WHAT ARE COOKIES? AND WHY WERE THEY DEVELOPED?
Cookies were invented to fix a fundamental problem on the internet. There is no organic reason for websites to have any memory of you the user.
Every page request is the first, in other words, and the site has forgotten you as soon as a page loads. Cookies enable websites to store a small amount of information in your browser, such as when you have logged in so that they can identify you.
A cookie can keep simple information like:
- A unique user ID
- Login session details
- Language or location preference
- Products added to a cart
Cookies do not save personal documents, photos or programs. They are plain text and can be read only by the Web site that installed them.
How Cookies Work on Websites
The first time you visit a website, the site sends a cookie to your browser. Your browser saves it locally. Each time you return to that website, your browser sends the cookie back to the server. This is a cookie set by the website and stored on user’s hard disk.
Cookies usually contain:
- The name of the website
- A unique value or identifier
- An expiration date
- Usage instructions
Informing this knowledge, the site fine-tunes its behavior to enhance functionality, performance or personalization.
