Interoperability guidance for vendors working with Google via the IAB Europe TCF

 

Google does not require ad technology providers to adopt IAB Europe TCF. This article describes how Google interoperates with those ad technology providers who have chosen to adopt IAB Europe TCF, and does not apply to those who have not adopted IAB Europe TCF. Ad technology providers who have chosen not to adopt IAB Europe TCF should adopt Additional Consent.

What to know before registering

If you are integrating with the IAB Europe TCF, please review the information below about how Google will interoperate with the IAB Europe TCF based on the content of the IAB Europe TCF’s Transparency & Consent (TC) string. Google may update this information from time to time.

For simplicity, we use the phrase “Google will work with you via the IAB Europe TCF” below to encompass several aspects of interoperability via the IAB Europe TCF, including but not limited to:

  • Bidding on bid requests Google receives

  • Sending bid requests from publishers using Google to bidders

  • Allowing third-party ad tracking and third-party ad serving to occur

Google Policies

The interoperability guidance below is intended to reflect Google's existing policy requirements, in particular the requirements of Google's EU User Consent Policy and our policies against fingerprinting for identification (for example, those contained in our Requirements for Third Party Ad Serving). Please note that our policies continue to apply and are more restrictive than IAB Europe TCF policies in some cases.

Purposes

For each purpose below, for Google to work with you via the IAB Europe TCF, the TC string must indicate that consent has been granted by, or legitimate interest has been established with, the user (as applicable).

Store and/or access information on a device (Purpose 1)

If you use cookies, mobile ad identifiers, or other local storage, Google will work with you via IAB Europe TCF if you are registered for consent for purpose 1.

In some jurisdictions, for example Switzerland, in certain situations, consent for Purpose 1 may not be asked for by the publisher via the CMP and, so long as the TC string appropriately represents this, Google will interoperate in those situations. In line with our EU User Consent Policy, this position is subject to change based on legal developments and evolving regulator guidance.

Select basic ads (Purpose 2)

Google will work with you via IAB Europe TCF if you are registered for ‘consent’, ‘legitimate interest’, ‘consent or legitimate interest’, or ‘not used’ for purposes 2.

Create a personalized ads profile and select personalized ads (Purposes 3 and 4)

Google will work with you via IAB Europe TCF if you are registered for ‘consent’ for purposes 3 and 4, so long as the TC string indicates that the user has granted consent for both those purposes.

Google will also work with you via IAB Europe TCF if you are registered for ‘not used’ for these purposes.

If you are registered for ‘legitimate interest’ for purposes 3 and/or 4:

  • If the TC string indicates ad personalization (purposes 3 and/or 4) is permitted under legitimate interest, Google will not work with you via IAB Europe TCF.

  • If the TC string indicates no ad personalization is permitted, Google will work with you via IAB Europe TCF.

If you are registered for "consent or legitimate interest as a legal basis" for purposes 3 and/or 4:

  • If there are no publisher restrictions, Google will work with you via IAB Europe TCF so long as your default legal basis is consent.

  • If there are publisher restrictions:

    • If the publisher restriction is for you to operate on the basis of consent, Google will work you via IAB Europe TCF in that circumstance.

    • If the publisher restriction is for you to operate on the basis of legitimate interest, Google will not work with you via IAB Europe TCF in that circumstance.

Measure ad performance (Purpose 7)

Google will work with you via IAB Europe TCF if you are registered for ‘consent’, ‘legitimate interest’, ‘consent or legitimate interest’, or ‘not used’ for purpose 7.

Apply market research to generate audience insights (Purpose 9)

Google will work with you via IAB Europe TCF if you are registered for ‘consent’, ‘legitimate interest’, ‘consent or legitimate interest’, or ‘not used’ for purpose 9.

Develop and improve products (Purpose 10)

Google will work with you via IAB Europe TCF if you are registered for ‘consent’, ‘legitimate interest’, ‘consent or legitimate interest’, or ‘not used’ for purpose 10.

Special Purposes

Ensure security, prevent fraud, and debug (Special Purpose 1)

Google will work with you via IAB Europe TCF if you are registered for ‘legitimate interest’ or ‘not used’ for special purpose 1.

Technically deliver ads or content (Special Purpose 2)

Google will work with you via IAB Europe TCF if you are registered for ‘legitimate interest’ or ‘not used’ for special purpose 2.

Features

Match and combine offline data sources (Feature 1)

Google will work with you via IAB Europe TCF if you register for feature 1, so long as appropriate disclosure has been provided to the user.

Link different devices (Feature 2)

Google will work with you via IAB Europe TCF if you register for feature 2, so long as appropriate disclosure has been provided to the user.

Receive and use automatically sent device characteristics for identification (Feature 3)

Google will work with you via IAB Europe TCF if you are registered for feature 3. However, we remind you that our policies prohibit fingerprinting for identification (for example, Requirements for Third Party Ad Serving), and we require that you adhere to our policies, which can be more restrictive than the IAB Europe TCF in some cases, whenever you work with us.

We actively enforce our policies and we're continuing to invest in technology to detect fingerprinting on our platforms.

Special Features

Use precise geolocation data (Special Feature 1)

Google will work with you via IAB Europe TCF if you register for this feature, so long as appropriate disclosure has been provided to the user and users appropriately opt-in to special feature 1.

Actively scan device characteristics for identification (Special Feature 2)

Google will work with you via the IAB Europe TCF if you are registered for Special Feature 2. However, we remind you that our policies prohibit fingerprinting for identification (for example, Requirements for Third Party Ad Serving), and we require that you adhere to our policies, which can be more restrictive than the IAB Europe TCF in some cases, whenever you work with us.

Macro requirements

To adopt the IAB Europe TCF, macros should be added to pixel URLs within creatives to indicate where in the URL the TC string should be inserted and sent onwards, as well as to identify which vendors are present.

Integration requirements

What are Google registration requirements ?

There are two things to distinguish:
  1. Google registration as a vendor. Please see the IAB TCF GVL registry (.JSON file) for Google’s registration as a vendor.
  2. Google’s requirements for vendors and publishers to work with Google. Please refer to Google’s Interoperability guidance for vendors.

Can publishers using the IAB Europe TCF work with vendors that are not registered on the GVL?

GVL through “Additional Consent,” which is a technical spec that CMPs can implement to add Google’s ad technology providers (ATPs) to consent messages.

CMPs must implement this spec for publishers to work with vendors on Google’s ATP list that are not on the IAB GVL.

Why does a publisher need to obtain consent for both Purpose 3 (Create a personalized ads profile) and Purpose 4 (select personalized ads) to serve personalized ads? What if a publisher wants to personalize ads for that user, but not build personalized profiles for them?

Based on our interpretation of the GDPR and ePrivacy Directive requirements, various guidance from the Article 29 Working Party and our own dialogue with DPAs, we have come to the settled conclusion about the appropriate lawful basis. Further detail on the nature and scope of processing including the applicable legal basis are also described in the Privacy Policy.

Google has not changed its consent requirements in relation to the TCF. Google customers (for example, publishers and advertisers) using Google ad platform products must comply with Google’s EU User Consent Policy.

Without consent for Purposes 3 and 4, Google will not be able to offer personalized ads. Specifically, with just consent for Purpose 4 and no consent for Google for Purpose 3, only non-personalized ads will serve. These requirements are in line with our existing Google EU user consent policy which states:

You must obtain end users’ legally valid consent to:

  • the use of cookies or other local storage where legally required [Purpose 1]; and
  • the collection, sharing, [Purpose 3] and use [Purpose 4] of personal data for personalization of ads.

Google Ad Manager publishers can choose in the user interface to enable or disable whether or not user visitation data can be used by Google to help create user interest categories in order to target ads. Disabling these settings does not prevent publishers and RTB buyers from serving personalized ads, although publishers will still need to obtain consent for Purposes 3 and 4.

Is AMP integrating with the IAB TCF?

AMP supports transparency and consent frameworks via the amp-consent component. Please check with your consent management platform (CMP) on their AMP support.
