Three Main Takeaways About Cookie

  1. Data Storage: Cookies are used to store small pieces of data on the user’s browser, which can keep track of their actions and preferences over time.
  2. Session Management: Cookies are widely used for session management, such as keeping a user logged-in as they navigate a website.
  3. Tracking: Various services use cookies to track users’ activities across the web, in order to deliver targeted advertisements and gain insights into user behaviour.  Note: This is an example HTML code. The details of cookies can vary based on specific context.


A “cookie” is an essential technology term in the digital landscape as it relates to how information is stored and used on the internet. Cookies are small data files that websites deposit on a user’s device to track their activities and preferences.

They are important because they allow websites to offer a personalized user experience, such as retaining user preferences on site navigation, shopping carts, and login information. Additionally, cookies are critical for web analytics and targeted advertising, as they help companies understand user behavior and tailor their strategies effectively.

However, while they improve overall usability and engagement, there can also be privacy concerns associated with their use, leading to regulatory measures such as cookie consent banners for transparency and user control.


A cookie, in terms of technology and web browsing, is a small piece of data that is stored on your computer or device when you visit a website. This small piece of data is used by the website to remember information about your session, like your login details, shopping cart contents, and more, to improve your user experience. Without the use of cookies, websites wouldn’t have the ability to remember these details about you, making for a much less user-friendly experience.In addition to improving the overall user experience by remembering your details, cookies also serve a number of additional purposes.

They allow website owners to collect analytical data about their users, such as which pages they visit, how long they stay, and whether they return, all valuable information for improving the website’s functionality and content. Cookies are also crucial for targeted advertising – they track your browsing habits in order to show you adverts that are more likely to be of interest to you. So, while cookies often get a bad reputation for privacy reasons, their main role is to streamline and personalise your online experience.


1. E-Commerce Shopping: When you browse an online e-commerce website like Amazon or eBay, a cookie will track and save your browsing habits. These habits can include items you’ve searched for, the pages you visited, and the items you’ve added to your cart. When you visit the site again, it uses this cookie information to personalize your experience based on your past interactions.

2. Social Media Platforms: Sites like Facebook, Instagram, and Twitter use cookies to refine the user’s feed content. By recording likes, shares, and search history, they can present more appealing or relevant information. Also, this data can be used for targeted advertisement purposes based on individual interest and activity.

3. Online Banking: Banks use session cookies for the security of internet banking. These cookies get deleted once a user logs out of their account, ensuring that no sensitive data remains on the device they’re using. This helps protect against potential threats of online banking fraud.
