CMP or consent management platform is a platform or a tool to take consent from the visitor to use his/her digital identity for marketing efforts.

provide a link or button (e.g. in the footer) that allows your users to reopen the consent modal and edit their preferences.

However, please note the following: it will depend on how those subdomains are defined. Are they just subsections of a project that belongs together like help.example.com or blog.example.com (and many other possible arrangements that are part of one and the same setup)? In such a case, using the same policy is appropriate. Problems arise when completely different projects which have little to do with one another and whose data collection practices also differ so significantly that they require different privacy policies.

Asking for consent when processing users’ personal data is one of the most important duties imposed on website owners by the GDPR.

Another value-add of CMP tech is that it can sniff the user's location and show the prompt just to EU residents. This helps to comply with the law while not intruding on non-EU user experiences.

haven’t consent tools been around for a while? Sort of! Ever since May 2011, when the EU Cookie Directive went into effect, most EU sites have added cookie notification bars to the top or bottom of their pages. This prompted many third-party solutions to pop-up, including WordPress plug-ins and the leading tool from Silktide. These tools are still around, and many sites continue to use them under the GDPR. However, these solutions were built for the older law, and the GDPR is much more specific about requiring explicit opt-in consent. Most of those older tools don't provide this, nor do they integrate with downstream ad partners, paving the way for the more sophisticated CMPs.

we make it easy to implement using our Consent by Geolocation feature that auto-identifies the location of the website visitor and applies the correct consent notice and behavior based on the visitor’s current location. For example, simply add PreferenceChoice Cookie Consent and Website Scanning to your website, and the functionality of your consent notice will automatically update to display a CCPA-compliant consent notice to a visitor in Los Angeles, and a consent notice in compliance with ePrivacy and GDPR to a visitor in London.
