How to Install Consent Mode V2 (with GTM and Cookie Information) - Live Demo

Learn how to install Google Consent Mode v2 in your Tag Manager with this easy-to-follow, step-by-step tutorial.
Our partner Lars Friis from MCB leads you through the entire setup process in Google Tag Manager, explaining everything you need to know, what each setting does, and how you can then ensure your implementation is successful.
A prerequisite for installing Consent Mode v2 is having a compliant cookie banner that collects and communicates consent signals with Google. Here we are using Cookie Information's consent management platform, a trusted Google CMP partner that offers a straightforward Consent Mode v2 implementation.

This is by far the best video on the matter, thank you for being so accurate!

[@anikojm]

Very useful tutorial, thanks!

[@cookie_information]

Thank you - it's good to hear that it's helpful 👍

[@touchhoneyUSA]

I don't use GTM, can i only use GA4 with Cookie information? Will that work?

[@BitteSEA]

Lovely!!! Thank you so much!

[@MrOron]

Best info yet!

[@dropitaly]

Thanks for this video, it's super handy. I've just had a chat with the Google implementation team and they say that GTM does not create the banner, for this, you would need a third-party tool to generate it (hence you channel name...)

[@bloodlinegate7]

Did you find a solution?

[@dropitaly]

You need to find a provider (see Google guidelines for this) and then follow this video. The providers are not free though.

[@besufkaddebebe4753]

Thank you so much!

[@oldadajbych8123]

Thanks for the tutorial. Now, it would be great to show an example of the implementation in the code. Thanks.

[@cookie_information]

Hi @oldadajbych8123 We are happy that you liked our GTM tutorial. For direct implementation in the code, please refer to this help article: support.cookieinformation.com/en/articles/8886647-consent-mode-v2-implementation We will also consider making a video about that very soon 🙌

[@EmirElezovic-fi6dg]

Hi Lars, thanks for this easy tutorial, it was very helpful. I'm currently trying out your cookiebanner and was wondering if there's supposed to be no data coming in in GA4 when someone declines all cookies? I was under the impression that cookieless pings would be sent and we would at least be able to see which pages were visited and how many users there were. I've tested this with debugview and realtime report in GA4. In both cases the data would only show after accepting the cookies.

[@larsfriishansen87]

I am glad you liked the video. Google consent mode needs quite a lot of data to be able to do modelling. You can see in your GA4 reports if modelling is active. Normally you need 50.000+ sessions per months to have modelling applied.

[@maialbaghdady8685]

Very useful video, thank you. I have a question, I noticed security_storage is denied, is it possible? is it configured with the other consent types?

[@cookie_information]

Hello! We're happy you found the video useful! The question is a bit unclear. The security_storage parameter is based on the necessary category. All of the consent states start as denied and change based on the consent that is given via the pop-up. The security_storage will always change to granted when the necessary cookies are accepted. If you have follow up questions, you are always welcome to contact our support center and they'd be happy to assist!

[@user-pw1hv4ez7y]

Thank u!!!

[@AnalyticsEvolution]

Would you please tell me which cookie banned you have used on the website? Shouldn’t I need to connect banner and consent tag on GTM?

[@cookie_information]

We've used a banner from Cookie Information - you'll need the cookie banner template called 'Overlay v2 - Consent Mode v2'. Right now, we're having a limited offer for new clients with 50% off. Check it out here: cookieinformation.com/registration-cmv2/

[@voitcorinna4998]

Thanks for the good video. I did all the steps and I ended up with the following error in the preview: A tag read consent state before a default was set. How can I eliminate this error? Could you help me? And if I publish everything, will older Consent Mode setups in GTM be overwritten or do they need to be deleted?

[@cookie_information]

[@MarieWoudwijk]

Hi Lars, I have a few questions. This is regarding advanced mode. For GTM the tags now have 2 triggers (in my GTM), consent mode update trigger and the conversion trigger for example, is it (and, and)? that both need to be triggered? Or is it enough if a build-in consent mode already exists? What I'm wondering is that during consent mode update (in the debug mode), not a single tag was fired except for the tags on which I added additional consent and the additional trigger consent mode update. Even including the consent mode update does not make all the other tags fire since the default setting is set on: doesn't require additional consent. The cookies were accepted but the tags were not fired with the trigger 'all pages' I have been struggling for over 3 weeks now... Hope you can help or anyone else. (I have set additional consent for the meta pixel.)

[@larsfriis1987]

When evaluating consent in non-google tags like the Meta pixel, you need to use a trigger that fires after the consent state is updated by the cookiebanner. If you use Cookie Information you can use the event called cookie_cat_necessary, that always fire after consent is defined by the user.

[@WoudwijkMarie]

⁠@@larsfriis1987and what if I use a different cookie banner? The action when consent is given is called: cookie_consent_update and this needs to be set after the other page load trigger? So with a delay? And what is no consent is given by a user? Then all consent is denied and no cookieless pings are being sent over, is this correct?

[@laurentiumarin1986]

Great video, in my case i installed with cookiebot but on page default is Granted for ad storage, analytics sotarage before i accept all cookies. And if accept all cookies, at on page default and on page update its showing granted. My tgarget is EU business, but why in your video its shoring denied before and after cookies accepted at ad storage, analytics storage and ad personalization? Am im doing somrthing wrong?

[@cookie_information]

Hello Laurentiu, We cannot know for sure what the issue is when using a different provider. If you try it out on our platform and still experience issues, you are welcome to contact our support team and they can help you troubleshoot!

[@youssef4532]

Amazing video, but i still have one problem and it's about the consent banner not showing up, can you please clarify if we must do something in order for it to appear? Because in GTM i can find the tags firing the way a visitor deny the consent, but still no matter what browser or device i use, i can't see any consent banner showing up

[@katerynastelnykovych2056]

Hi! In this implementation, GA4 fires just right after "denied" default consents. When the user updates consents, this tag doesn't fire again. I assume it's advanced consent mode settings. In this case, GA4 receive updated consent from the user or not? I don't know how to check what happens if I am denied consent on the banner. I am worried that all default consents are "denied" and GA4 will not send any data at all.

[@adrianmartinez7283]

Don't worry, this option is only so that unless the user accepts the cookies they will not be loaded, it is well configured, avoid any errors

[@mortezafathollahi5449]

What would happen if we set default value to "granted" and without displaying any banner to the user? Would all tags fire correctly? I'm asking this question in the context of countries with less stringent legal requirements regarding data privacy.

[@larsfriis1987]

If you set the default to granted, all tags will fire even though the user does not consent, and your tags will like up to Googles requirements for Consent mode v2. However, your site will obviously not be compliant with GDPR and cookie laws.

[@scaryviking8657]

Great video. But I have a problem: When loading a page, the consent state is set really late, and all of my tags that use the "require additional consent"-function fail to fire, because the trigger happens before the consent state is set. 1) I have made sure that the Cookieinformation-tag has priority value of 0. 2) I have made sure that my event tags have working triggers (when I remove the "require additional consent" form the tag, they fire just fine). How do I make sure that Tag Manager sets the consent state BEFORE my tags fire?

[@larsfriis1987]

If you use the cookie information Google Tag Manager template, default consent should be fired as some of the very first events. If your events are faster than that, you will need to create a trigger group with your event combined with the "cookie_cat_necessary" event which is fired by cookie information once the consent is updated and ready

[@christianthrige]

Hi Lars! Thank you for the guide, works i believe. However when i compare my setup to your, in my tag assistant "consent" summary, i have a Event Consent State called "Wait_for_update", which is denied even though i accept all. How come? On yours i can see, its not even visible in the first place? :)

[@cookie_information]

Hi Christian, This is not a consent state, it's just a parameter that handles waiting for tags. It's mentioned in the video. You can read more about it here: developers.google.com/tag-platform/security/guides/consent?consentmode=advanced#gtag.js_1:~:text=Optional%3A[…]sent%20management%20platforms

[@Lisa_M.322]

Hi Lars, I rally like this video but if I remove the cookie banner from the source code of my website I cant get access to my website anymore but my work Material can which seems very unusual/ strange to me. Its a website built with WIX. If I add the banner to the source code again I have access to my WIX again and the tracking via the template works, although the cookie banner is implementiert again in the source code, but it is basically not set up. So there is a cookie banner in the source code, but its unused becsuse tracking is done via the template and if the banner is removed from the code, I no longer have access to my site Maybe removing the banner from the source code is only recommemded for CSS sites?

[@hannes4963]

Hmm, on the second page impression: Why is the consent only being updated at the second consent event (27) instead of the first one (21)? Meaning if I would need tags to be firing at the window loaded event (26) with consent, these wouldn't fire because the consent update only happens afterwards at 27. That's what happening at my setup and therefore showing the error: "A tag read consent state before a default was set " Thanks!
