Learn about what a CMP is in this article.
Stands for a Consent Management Platform. A CMP is a technology used by websites to allow users to give their consent for websites to process their personal data using cookies or trackers. A CMP makes consent collection easier and more transparent, helping to build trust with visitors and comply with data privacy legislation.
When first visiting a website, a CMP usually displays a popup message or banner at the top of the page for requesting consent. The message consists of what data is collected, how it will be used, and who will access it. The CMP will allow users to customise what they consent to by adjusting which third parties can access data and the categories of cookies that can be stored. Before consent is obtained, scripts are usually blocked from running.
The notifications allow users to opt in and out of cookies and notify users of which information is collected if they accept cookies. A CMP also tracks who consents and who ops out using a cookie or by the user's IP address.
Cookies capable of collecting personally identifiable information need to get consent from users in order to place the cookies on their devices. The cookie notifications reflect an EU data privacy protection law, called GDPR (General Data Protection Regulation). Websites that perform actions, such as performance, analytics, advertising, setting third-party cookies, and use tracking cookies for personalisation and analytics should use a CMP.
Cookies can become a privacy risk as they can reveal information about the user's browsing history. Advertisers can view the cookies to find out where the user has been, what their interests are, and more. They can then use this information to show personalised ads. GDPR was designed to protect user's privacy by making consumers aware of what information is collected about them and allowing them to opt out.
