Best Consent Management Platforms for Publishers in 2023

Updated on: December 21, 2023
Since the onset of the GDPR, consent management has become a top priority for publishers and advertisers alike.

If you are unaware of the basics of a Consent Management Platform, you can read the first part of the series here. We have covered the following: What is CMP? Why do you need it? is it compulsory? what is the IAB CMP validator? What should you consider about a CMP? Now let’s go further by discussing the best CMPs for publishers.

Sidenote: We aren’t associated with any of the CMPs listed here, and we restricted our list to include the top 6 CMPs. Of course, you can find more that fits your requirements.

Top IAB-registered Consent Management Platforms (CMPs)

1. OneTrust

OneTrust is the most preferred CMP among the top publishers at the moment. It works closely with IAB and IAB Europe to support TCF v2.0. Other privacy policies OneTrust supports include CCPA, GDPR, LGPD, ePrivacy, and DAA AdChoices.


  • Free version available to help you become GDPR compliant.
  • Real-time dashboards to test and report on experiments you’ve conducted to improve opt-in rates. 
  • Tools to assess security risks related to your site’s third-party vendors (data processors).
  • Consent notice based on the visitor’s geography.
  • AI for automating regulatory tasks and identifying risks. For example, you can predefine how to respond to requests through a drag-and-drop automation builder. So when a request is submitted in the future, the AI can automatically perform the workflow without any human interaction.


  • OneTrust handles many privacy laws, so you do not have to worry about separate policy implementations.
  • It supports easy integration with existing tech stacks like Adobe Advertising Cloud, Facebook, FreeWheel, mParticle, Salesforce Audience Studio, and more.
  • No code is required to integrate OneTrust for blocking tracking technologies until the visitor consents.
  • It provides analysis and insights to help publishers in increasing opt-ins.

What’s Next?

Every Consent Management Platform will have some common and exclusive features for publishers. Privacy policies like CCPA and GDPR require you to ask for the user’s consent and make you responsible for maintaining and securing the collected data (once the consent is given).

You are supposed to have an accurate audit trail explaining who consented, how the consent was taken, and what was told to the user while the consent was being taken. You should also be able to delete the data or provide it upon the user’s request.

The above-mentioned CMPs are capable of all the arrangements necessary for compliance. But the companies can also offer all the services separately in a modular fashion. You can choose to take all the services from the same company or separate services based on your requirements and integrate them. Assessing your needs before choosing the CMP for your website will always be better.
