Best Consent Management Platforms (CMPs) for Publishers

Best CMP
We receive queries from publishers on CMPs and more often than not, they just need to know the best Consent Management Platforms in the market. If you have the same question, we got the answer.

If you are not aware of the basics of a Consent Management Platform, then you can read the first part of the series here. We have covered: What is CMP? why do you need it? is it compulsory? what is the IAB CMP validator? and what should you keep in mind with regard to a CMP?

Now let’s go further by discussing the best CMPs for publishers. We are using Adzerk’s CMP tracker as the source of our data. It considers the top 10K US and UK sites to know which CMPs are leading the market.

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.

What’s Next?

Every Consent Management Platform will have some common features and some exclusive features for publishers. Privacy policies like CCPA and GDPR not only require you to ask for the user’s consent but also makes you responsible for maintaining and securing the collected data (once the consent is given).

You are supposed to have an accurate audit trail that can explain who consented, how was the consent taken, 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 you can take separate services based on your requirements and integrate them together. It will always be better to assess your needs before choosing the CMP for your website.
