# IAB TCF
Who is part of the TCF?
* Compatible CMPs are officially referenced after full audit and validation for each version.
* Advertising industry players aka 'vendors': adserver, dmp, advertising measurement tool.
* Some advertising players are not in the TCF, so Google has developed the Google Consent mode for these players.
* The major advertising players use TCF as the single standard for the data/consent chain.
* In its first version TCF allowed the reading of consents from one site to another (global consent) this function is not allowed by Google in V2.
Who is the TCF for?
* TCF is potentially applicable to all digital devices: website, mobile app, etc.
* It is preferred for sites and apps with a large audience monetization: media, advertisers with advertising.
* Its adoption is not massive because there is a strong impact on the user experience.
* The trade-off between business, project and brand/customer relationship issues must be taken into account.
What are the impacts?
* The trade-off between business, project and brand/customer relationship issues must be taken into account.
* TCF will be a CMP project to manage and implement.
* Can I test on a TCF template? YES, YOU CAN.
Will TCF have a negative impact on my consent rate?
NO.
Why: because the first screen that collects 99% of the consent will be little changed except its text. The default one from the IAB or a modified text validated by IAB. The impact will therefore be minimal
By passing the TCF I would have to resubmit consent to my entire audience?
YES.
Why: to have the totality of my audience with an exploitable consent in the framework.
What are the advantages of taking the TCF ?
* The main interest lies in the collaboration opportunities with TCF Vendors.
* These opportunities are accessed on audience monetization and advertising mainly.
* Be able to quickly test and activate new TCF Vendor devices based on the chosen configuration.
* Supporting the only advertising industry standard in the context of consent and GDPR
Disadvantages of taking the TCF ?
* You must adhere to all the specifications.
* The UX of the preference center is broad and complex. The IAB purposes are mandatory and cannot be merged with your own purposes.
* It is necessary to follow the evolutions of the TCF according to the current events and following a timing imposed by the IAB.
* In case of a new collaboration with a vendor, it will be necessary to wait for the consent to resubmit or to resubmit to the whole hearing.
Migration to the TCF?
* This is a CMP project with purpose and design choices on the preference center.
* The consent will have to be resubmitted to the entire audience to be available in the framework.
* Make choices upstream, particularly on vendors, and measure the potential impact.
* Stay alert and responsive to our recommendations and to changes in the framework.
Do you have any examples of clients using TCF?
