Up until a few years ago, if you’d asked me what a cookie was I’d have told you it was a crumbly biscuit with chunks of delicious chocolate best enjoyed with a nice cup of tea. But there is also another type of cookie, an electronic one, that’s arguably not as loved or as understood as the biscuit variety.
If you’ve read articles about cookies then you may have seen many negative things about them. Some people believe they are intrusive and act like ‘Big Brother’ tracking your every move as you browse the Internet. Equally you may have read the positives; that cookies are harmless and many people believe that they enhance your online experience.
So what’s all the fuss about cookies and what does it all mean? Here’s a quick guide to help you understand what cookies are.
What is a cookie?
Perhaps the best way to begin describing a cookie is to tell you what they are not. Contrary to what most people believe, they are not programs. In fact, a cookie doesn’t do anything other than store data. They are plain text files that typically consist of a site name and unique user identification.
How do cookies work?
A cookie is applied to your computer when you visit a website for the first time. If you return to that same site, your computer checks to see if it has a cookie that is related to it. This basically means that is checks for one containing the same site name. The information contained in that cookie is then sent back to the website.
This means that the website knows that you have been there before. In some cases what then appears on screen is customised to you, based on the fact that you’re a returning visitor, in an attempt to enhance your onsite experience.
Why are cookies good?
Some cookies can be simple and others more advanced. Many websites use them to record site metrics for example if you are a new or returning visitor, how long you spend on each page, where you click and even your preferences for how a page looks and the colours and images used on it.
They can also be used to store data such as, recording what’s in your shopping basket (adding items to it as you click) and remembering them when you return to make your purchase or when you select ‘remember me’ storing this detail to avoid you having to log in every time you visit that particular website.
What are the bad things about cookies?
So what’s the big deal? Well the answer depends on how you feel about company’s storing information on you. There is nothing extraordinary about the information cookies gather but you may or may not like the idea of your information being used to target you for specific products or special offers. Of course not all websites use these types of cookies. Many websites are interested in looking at how visitors use their website and in turn use this information to make improvements going forward.
