Install with Google Tag Manager

One tag in GTM. Live on every page.

Velo loads through a single Custom HTML tag in Google Tag Manager, so it fires before your other tags and powers Consent Mode v2 across your whole site.

Open your GTM container

Google Tag Manager is itself the tag manager, so there is nothing extra to install — just open the container already deployed on your site and add Velo as a new Custom HTML tag.

Add a Custom HTML tag

In GTM, create a new tag, choose Custom HTML, and paste the Velo snippet below.

Fire it on Consent Initialization

Set the trigger to Consent Initialization, All Pages so Velo loads first and Consent Mode v2 is set before anything else runs.

Submit and publish

Publish the container. Your banner is live. Pick the style, languages and regions in the Velo dashboard, no code changes needed.

<!-- Velo — Custom HTML tag in Google Tag Manager -->

Hand this to Claude or ChatGPT

Paste the prompt below into Claude or ChatGPT. It walks you through installing Velo on Google Tag Manager step by step, tailored to your setup.

I want to install the Velo cookie consent banner and Google Consent Mode v2 layer on my website using Google Tag Manager. Please walk me through it step by step for Google Tag Manager. The native method is to add a new Custom HTML tag inside my container: in tagmanager.google.com, open my container, click Tags, then New, choose Custom HTML, and paste this exactly:
<script src="https://cdn.veloconsent.com/v1/velo.js" data-site="your-site-id" defer></script>
Tell me which trigger to attach so it fires before consent is decided (Consent Initialization – All Pages), then how to Submit and Publish. Show me how to confirm the banner appears on a live page and that Consent Mode v2 is firing in Tag Assistant or the dataLayer. Ask me clarifying questions if my container setup or plan changes the steps.
