It’s almost here, CMP (consent management platform) D-day! The question is, are you ready?

On October 15, Google and other demand sources are ramping up the compliance requirements again, and this time, it’s serious!

Publishers will receive a message similar to this below:

tcf notification

“IAB TCF V2.0 errors detected – we’ve detected an issue on your IAB TC string on one or more of your sites or apps. These errors may affect your ability to serve ads to European users. A detailed report is available on the EU user consent page.”


TCF or Transparency & Consent Framework, was created to enable consumers to provide or withhold consent regarding their data being processed by online platforms. At the same time, the framework gives consumers the ability to gain control over how vendors may use their data.

You might wonder why there was a need for a TCF V2.0, and what was wrong with V1.0? Publishers generally did not like the first version as many loopholes existed, which favored AdTech vendors. However, as TCF was one of a kind and a first for the advertising industry, it can’t be expected to be perfect the first time around.

In fact, IAB and its creators expected new versions to emerge from V1.0.

The new version of TCF has focused on improving the original framework by increasing consumer transparency and providing greater control to publishers.
