When you look at the internet, every part of it has a script. From the advertisements on your browser to the pop-ups that appear as you browse, there is always some kind of script running in the background. Cookies are an example of this—they’re tiny pieces of script that have played a significant role in the booming ad tech industry. However, in the context of a consent management platform, a cookie script is a little piece of JavaScript that you can add to your site to keep things compliant and make sure your site only stores cookies with consent. In this article, we will explore the dual meaning of the term and also how cookie script helps to keep it compliant with data protection laws.

What is a cookie script?

A cookie script, also known as a JavaScript cookie, is a snippet of code embedded in a website that handles cookies. It is typically written in JavaScript and executed by the user’s browser. The script enables web developers to interact with cookies, providing a mechanism for managing user preferences and maintaining session information.

Cookies are most commonly used to track your online activity and help companies market their services. It’s important to note that cookies are not inherently bad—in fact, they can be quite useful! But there is a fine line between using them in ways that benefit the user and in ways that don’t. Privacy laws like GDPR have regulated the use of cookies by only allowing their use with consent from website visitors. This applies to cookies that track or enable the storing of personally identifiable information of the visitors. 

In the context of a consent management platform, Cookie script can also be referred to as a piece of javascript used by CMPs—like CookieYes, which is one of the most popular platforms out there to manage the use of cookies on your website. This helps keep your site compliant with GDPR and other privacy laws because it ensures no third-party cookies can be stored on your site’s visitors without their permission.

Why use cookie consent script on your website?

These are the main reasons why you might want a cookie consent script installed on your website:

Ensuring compliance

You may be subject to many different laws and regulations. If your website uses cookies, you need to ensure that you comply with the terms of those laws and regulations. For example, if your website sells products or services to people who live in Europe, you must make sure that you comply with laws like GDPR and the ePrivacy Directive.

Cookie consent scripts are one way to help you achieve compliance with GDPR requirements by showing visitors a pop-up when they first visit your website that asks them for consent to store cookies on their device. If they agree, then you can use cookies as usual and track visitor behavior across multiple visits; but if they don’t agree then you won’t be able to store any information about them at all.

Respecting user privacy

This is the most important reason to install a cookie consent script on your website. By requiring consent before allowing any third-party cookie scripts to run, you are respecting users’ right to control their own data and protecting them from being tracked without their permission by advertisers or other companies that may want access to the information they provide while browsing your site.

Also, this way the users are aware of what type of cookies are being used, and why and how their data will be used. This helps them to make an informed decision. 

Improving user experience

Cookie consent scripts make it possible for you to tailor your site’s cookies based on the user’s preferences. This can be incredibly helpful if you want to create a digital experience that caters more specifically to individual users. The user can choose whether or not they want their data collected and stored, and with this information in hand, you’ll be able to finely tune your site’s functionality so that it serves the needs of each visitor.

The cookie consent script checks if the domain is valid. If it is, it will load a single CookieYes cookie necessary for providing its consent management services.

This gives users more control over their data and allows them to decide whether or not they want to be tracked by websites.

Additionally and most importantly, it helps comply with privacy laws.
