Everything you need to know about cookies

We always see “accept all cookies” on websites, but what are cookies? Are they safe?

What are cookies?

Cookies are little bits of code that a website saves in your web browser when you visit in order to keep track of what you do there and other information about you. They do all kinds of useful things – like remembering your preferences, what you put in your cart, or where you’re located – so that your web browsing experience can be better. Cookies are also the primary way advertisers track your activities on the internet in order to show you more targeted ads and offers.

Are cookies good or bad?

In short, cookies allow companies and websites to identify a device and remember it the next time that they see it. This can be good or bad, as it depends on how that information is being used. Keep reading to learn the basics.

Types of internet cookies

Internet cookies can be delivered by all sorts of different people. Most websites leave several cookies on a visitor’s device, but it’s worth understanding the differences between different

Types of cookies.

First-party cookies are delivered to your device by the website that you are visiting. These can be helpful as they are used to remember your preferences, such as displaying the site in English and allowing the site to offer you a more personalized experience. They can also remember what is in your cart which is great for holiday shopping.

Third-party cookies are those which are placed on your device by advertisers and are used totrack your device after you have left that website and continue to follow you around the web.

They allow the advertisers to serve you with personalized ads. Think about a time when you looked at a certain item, like a shirt, on a shopping website, but didn’t buy it. Then you saw that shirt in an ad on your Facebook or Instagram feed. The cookies allow the advertisers to recognize your device when you visit other websites and display their targeted ads. These cookies can persist on your device for over 30 days if you do not clear them yourself.

Companies are starting to allow users to opt out of third-party cookies, so advertisers are adapting to other tracking methods.

Another flavor of internet cookies is a session cookie. Session cookies are used when you log into a website by storing your login credentials every time you visit a particular site. Websites also use session cookies to improve site performance like fast page loads.

What kind of dangers can cookies pose?

If you’re a frequent internet user (and just about everyone is these days), it’s wise to understand the risks that cookies pose so that you can best determine when to delete them.

Privacy risk is the biggest concern for most people. It is typically not easy to discern exactly what data companies are collecting with cookies and who they are sharing that information with. Typically, advertisers and data brokers are the ones collecting information this way.

Another danger posed by cookies is cookie fraud. This involves the use of cookies to fake the identity of someone else to gain access to their account or use their identity to commit a crime.

To reduce the risk of cookie fraud, it is important to avoid potentially malicious sites and keep your browser well protected by installing the latest updates when they become available.

Why do I see all those messages asking me to “Accept all cookies?”

Over the past couple of years, you may have noticed that a majority of websites have started to include a pop-up message asking you to allow them to place cookies on your device. This is done to comply with data privacy laws which were designed to protect users’ personal information and force companies to state what data is being collected and how it is being used.

The basic idea being these laws is that companies need to tell internet users that their data is being collected and if it is shared or sold to other companies and that they should be able to say no. If it is a company that you trust or if you prefer a more personalized browsing experience, then you may prefer to accept cookies.

How to control your cookies

Now that we have a better understanding of cookies and how they are used, we can review the best methods for controlling cookies on your devices thereby allowing you to control your privacy more effectively.

For cookies that are already on your device, you can clear them yourself. In most internet browsers, within their settings, you can manually clear your cookies or enable it so that cookies are cleared every time you close your browser. To prevent cookies from being placed on your device in the first place, you can sometimes opt out of third-party cookies within your browser settings or decide what cookies you want to allow on a particular website by interacting with the cookie banner on the site. Certain cookies that are necessary to the site's performance will not allow you to opt out, but other types such as those used for advertising will allow you to opt-out.
