Cookie Checker for Websites

Cookies are the most used technology for tracking website visitors, as well as collecting and sharing their data for a range of purposes – like remembering log-in details or shopping cart contents, displaying targeted ads on your domain, or providing you with data about your website’s performance with its users.

But cookies are also notoriously privacy-unfriendly as the data that they collect from users and share with third parties range from anonymized information to the highly private and sensitive data – like behavior, location, purchase history, preferences, orientations, convictions, beliefs, and personal traits.

Data privacy laws in the EU, California, UK, Canada, Australia, Brazil, South Africa, and New Zealand (among many other countries and regions) have changed the ways in which your website can use cookies – in many places, strict rules apply.

Some require you to obtain prior consent from users before running any cookies on your domain, while others require you to present your website’s visitors with choices to opt-out – and almost all require that your website features privacy notices that inform your users in detail about every cookie in use on your domain.

Yes, every cookie and other tracking technology, including information on:

Technical specifications,
Provider,
Purpose,
Where data is sent to,
And what kinds of data are collected.

But knowing all cookies on your website is only half the job done – because once you’ve managed to get full transparency, most data privacy laws also require you to be able to control them and, more importantly, to hand over control to your website’s visitors.

In short, transparency and control are the two most important things for you to get right when it comes to data privacy compliance on your website.

And this is difficult to achieve if you don’t have a cookie audit tool like our CMP at your disposal.

What cookies does my website use?

Websites come in many different shapes and sizes, but almost all use cookies for purposes ranging from basic site function to intricate end-user tracking.

Protecting the data privacy of your website’s visitors really comes down to knowing and controlling your website’s cookies.

Exactly what types of cookies your website uses depends on several things, such as if you use third-party services like Google Analytics or HubSpot, if you use social media plugins or if you embed videos, if you have a web shop or if you display ads on your domain.

Did you know that websites on average use 20 cookies?

Third-party services will set third-party cookies on your website, and these will often collect and share end-user data that fall under the legal definitions of personal data/personal information – like search and browser history, IP addresses, cross-website tracking information, user behavior on a website, device data, shopping history, and much more…

Websites typically have several third-party cookies in use that require the right compliance solutions to run legally in the several major regions of the world.

Common third-party cookies that most websites use include Google Analytics cookies that measure website traffic and conversion rates on your domain. These are regulated by data privacy laws in large parts of the world (EU, UK, Canada, California, South Africa and many other places).

But your website may also have cookies that you’re not even aware of and unable to detect yourself, since –

72% of cookies on websites are loaded in secret by other-third party cookies.

18% of cookies on websites are “trojan horses”, i.e. cookies that hide as deep as within eight other cookies, loading each other without your knowledge.

50% of trojan horses will change on repeated visits by users to your website.

What are cookies? And what cookies does your website use?

Okay, so what are cookies anyway?

Cookies are units of data that were invented in the early 90s, named after the fortune cookie because of their structures as containers bearing a message. And that’s exactly what cookies are, only the message can be all kinds of data, even the most private and sensitive information about an individual.

Illustration of webpages - Cookiebot — Websites use an average of 20 cookies, most of these are third-party cookies that need end-user consent.

Initially designed to function as the recall of a website, cookies have developed over the last 30 years to become the supply chains of the internet economy, harvesting vast amounts of data from end-users that is then grouped, profiled and, in turn, sold in real-time bidding auctions for targeted advertisement online, among many other purposes.

A 2019 Cookiebot CMP report revealed how third-party cookies from Google and Facebook were hiding on EU government and health websites, collecting sensitive data about users without their consent.

With data privacy laws emerging all over the world – from state-level bills in the US to an upcoming new ePrivacy Regulation in the EU – cookies, trackers and the tracking technologies of tomorrow are expected to be even more regulated. And it all comes down to what happens on your website.

Does my website use different cookies?

Broadly speaking, cookies come in four types –

Necessary cookies
Preference cookies
Statistics cookies
Marketing cookies

Only necessary cookies are exempt (e.g. from consent requirements in the EU), nonetheless you still need to know of them and tell your end-users about them in your website’s privacy notice/privacy policy.

Statistics and marketing cookies make up the majority of trackers on most websites today, because they’re often third-party cookies that are set on your website when you use third-party services, like Google Analytics, HubSpot, Facebook, Twitter, YouTube etc.

These cookies always need the prior granular consent of end-users, or (in California) the end-users need to be presented with a choice of opting-out of having these cookies collect their data.

Maybe you’ve heard that third-party cookies are slowly being replaced with new tracking technologies?

It’s true that third-party cookies are being phased out in many website browsers, including Chrome and Safari, but the new technologies poised to replace them still operate in the same way: collecting and processing user data for different purposes.

In other words, personal data/personal information will still be processed by these new technologies, and end-user consent (in the EU, UK, South Africa and Brazil) as well as opt-out options (in California and soon Virginia too) will still be needed if your website is to use them in a legal way.

In fact, a cookie is already an umbrella term that covers many different tracking technologies, such as –

HTTPS/JavaScript cookies
HTML5 Local Storage
Flash Local Shared Object
Silverlight Isolated Storage
IndexedDB
Ultrasound beacons
Pixel tags

Using a cookie checker like Cookiebot CMP enables you to know exactly what cookies your website uses, to control them and to offer end-users consent and opt-out choices.
