Cookies are one of the most popular ways of tracking people’s activities online. Almost every website uses them for multiple purposes like storing shopping cart information, user preferences, user session data, etc. With so much usage of cookies, comes the need to have a better understanding of what they do and how they can be (mis)used. A website cookie checker can help you with that. We will discuss why checking for cookies is necessary to comply with privacy regulations and what are the best (free) tools available for it.

Before that, you can read more about internet cookies and understand how they work.

What is a cookie checker?

A cookie checker is an online tool that enables anyone to check the cookies used on a website by entering the URL of the website. With a cookie checker tool, you can see what types of cookies are used, who set them and where they are set, whether third-party cookies are being used, and the lifetime of the individual cookie.

These tools are extremely useful for both individuals who are concerned about their online privacy and websites that want to comply with various online privacy laws.

Cookie checkers vary in complexity and accuracy. Simple checkers provide only a few details while other tools dig deeper, providing specific details about individual cookies, who sets them, and the cookies’ purposes.

How does a cookie checker work?

A cookie checker crawls through a website’s home page and activates all cookies set by the site server. It identifies and groups the cookies based on their properties, and then matches them against its cookie library. Finally, it creates a detailed cookie report that tells you the number of cookies, as well as details such as their domain, type, purpose, expiration date, path, secure flag, and other properties. You can use this report in your privacy or cookie policy.

This way, you can get complete transparency about which third-party cookies are tracking visitors’ activities on your site.

Why check cookies on a website?

A cookie is a small text file that a website places on your computer as you browse. Cookies make the interaction between users and websites faster and easier by saving and retrieving information. However, some cookies can track personal information, which often leads to an invasion of privacy. Because of this, privacy laws like GDPR, DSGVO, ePrivacy Directive, CNIL, and CCPA regulate how cookies are used. Websites cannot use non-necessary or non-technical cookies without users’ cookie consent, and they should be allowed to opt out of it as well.

Read more about cookie law.

You should check the cookies set by your website to ensure they comply with relevant privacy laws. This means checking the type of cookies and what they are used for. You may also need to check the cookies set by any third parties you embedded on your website as well. Confirming these details will allow you to be transparent about your site’s data collection and processing activities, ensuring compliance with global privacy rules, such as the EU GDPR or CCPA.

As website users, checking cookies enables them to understand what, how, and why cookies track their information. This enables them to make an informed decision on whether they consent to the website using them.
