Tracking cookies, in short
Free automatic cookie tracker with Cookiebot CMP
Cookies play a crucial role in both basic and complex operations on most websites today, and the most widespread type of cookies on the internet are so-called tracking cookies, used by websites everywhere (most likely yours too) to run analytics services, social media plugins and marketing tools – often at the expense of users’ privacy, since their personal data is processed to serve such services.
But the internet economy is changing, driven in large part by a strong and growing consumer demand for transparent solutions that enable end-users to protect their data privacy online, as it has become their right under most major data privacy laws in the world today.

The use of tracking cookies is now regulated in places like Europe, California, Brazil, South Africa, Canada, Australia and many other countries and regions around the world.
Some data regulations require that you obtain the explicit consent from end-users before activating tracking cookies on your website (such as the EU’s GDPR or Brazil’s LGPD), while others empower end-users with the right to opt-out of having their personal information collected via tracking cookies and then sold (such as California’s CCPA/CPRA).
At the end of the day, living up to the emerging data privacy requirements for controlling tracking cookies on your website can be painstakingly difficult since they most often are set and operated by third parties, such as Google or Facebook, often loaded in secret by other tracking cookies, and frequently change upon repeated visits.
Signing up to Cookiebot CMP by Usercentrics brings you unrivaled cookie tracking software and scanning technology to your website with just a few lines of JavaScript – plug-and-play without any need for on-site manual implementation.

What is a tracking cookie and how does it work?
Tracking cookies is the commonly used name for a wide variety of different tracking technologies in use on the internet today.
The most famous are third-party marketing cookies, which work as tiny files that get set on an end-user’s browser when they visit your website. From there, they will process and share personal data with their third-party providers – sometimes for years.
Tracking cookies can collect, process and share all kinds of personal (and sometimes sensitive) data from your website’s end-users, such as their search and browser history, IP addresses, on-site behavior, past purchases, Google searches – and they are often used to serve targeted advertisement back at the end-user, as they move across the internet.
You might have heard that third-party cookies will be phased out by Google’s Chrome in 2023, and wonder why you should care about tracking cookies on your website if they’re going to disappear anyway?
While it’s true that third-party cookies look to meet their demise in the near future, most other types of tracking cookies (such as Local Storage, IndexedDB and Web SQL to name a few existing ones), will continue to be used throughout the internet – and will all still require end-user consent or opt-out options under the world’s emerging data privacy laws.
While some tracking cookies will disappear, new ones will develop, and the growing consumer demand for websites to be in data privacy compliance, particularly around the issue of cookies and trackers, underline how important it is for websites and online businesses to pay close attention to how they handle their user’s personal data.
In other words, tracking cookies are everywhere, most likely also on your website, and end-users want transparency and control – but it can be hard to manage on your website without cookie tracking software designed for this purpose specifically.

Tracking cookies, in detail
Cookie tracking software to balance data privacy and data-driven business
Tracking cookies are everywhere – they form the backbone of digital advertisement and are therefore the target of many data privacy regulations and their enforcement authorities.
Under the EU’s GDPR – which applies to any website that has users from within Europe, regardless of where in the world the website itself is located – it is your responsibility as the website owner/operator to always make sure that you have a clear handle on your website’s tracking cookies: you are required to offer end-users full transparency (including details about technical specifications, duration, provider and purpose of each tracking cookie in use), and end-users must be able to decide for themselves whether they will allow personal data to be collected, processed, and shared by your domain.
But the problem with tracking cookies is that they are almost impossible to control without deep scanning cookie tracking software.
When a user visits your website, and a tracking cookie is loaded on one of your subpages, the tracking cookie often signals to other tracking cookies to activate themselves too.
In other words, one tracking cookie can activate hundreds of other tracking cookies, making the legal requirement for you to always know about and control the cookies on your website a very difficult job.
A recent collaborative study by Ebiquity and Usercentrics utilizing the deep-scanning technology of Cookiebot CMP found that over 92% of websites activated and used at least one tracking cookie without the end-user’s consent.

End-users are increasingly demanding real solutions to the sense of false control often felt, when websites use tracking cookies without their prior consent.
That staggering number of non-compliance indicates the dilemma that plagues a lot of online businesses and websites today: how to balance data privacy with data-driven business, how to aggregate data vital for revenue while at the same time respecting end-user consent and following data privacy regulations in places like Europe, Brazil, or California?
That’s where Usercentrics comes in, offering its unrivaled Cookiebot CMP as a plug-and-play solution that automatically makes your website compliant with most major data privacy laws in the world.

FAQ
How do cookies track users?
Cookies save and store data from users when they visit websites, sometimes across multiple websites (known as ‘cross-site tracking cookies’). Cookies are small text files that can contain any kind of data about users (e.g. search and browser history) and share it with third parties. Some cookies are necessary for the basic functions of websites, while others are third-party marketing cookies collecting and sharing data about users for the purposes of targeted advertisement.
What can cookies track?
Cookies can track any kind of data about users, such as search and browser history, what websites they previously visited, what they googled earlier, their IP addresses, their on-site behavior such as scrolling speed, where they clicked and where their mouse hovered. Cookies that process personal data from users most often need end-user consent to operate legally on your website.
How do tracking cookies work?
Tracking cookies – also known as ‘third-party marketing cookies’ – work by placing themselves on a user’s browser and often stay for durations up to years.

Are tracking cookies legal?
Tracking cookies need end-user consent to operate legally in many parts of the world, such as the EU, Brazil, South Africa, Japan, and several other places. Under the EU’s GDPR, tracking cookies need the explicit consent from users to even be activated and start operating, i.e. no personal data from EU users is allowed to be collected and shared by tracking cookies before users have said a clear ‘yes’.
What tracking cookies do I have on my website?
Most websites use tracking cookies, whether the website owner/operator is aware of them or not. Embedding YouTube videos, integrating social media plugins or running analytics services like Google Analytics or HubSpot will set tracking cookies on your domain that will collect and share personal data from the users visiting your website. It’s important that you know what cookies your website uses so as not to infringe your end-users’ data privacy.
