Google Tag Manager

Connect your Zellify funnels with Google Tag Manager (GTM) for attribution and conversion tracking.

Why use GTM?

  • Centralize all tags in one place

  • Publish changes without code deploys

  • Fine-grained control over triggers and load performance

Over 30% of websites use tag managers; GTM is the most widely adopted.

Setup

1) Access Google Tag Manager

Go to https://tagmanager.google.com and sign in with your Google account.

2) Create Account and Container

  • Click Create Account

  • Account Name: Your company name

  • Country: Select your country

  • Container Name: Your domain (e.g., subscribe.myapp.com)

  • Target Platform: Web

  • Click Create and accept the Terms

3) Get GTM Container ID

Your container ID looks like GTM-XXXXXXX.

You do not need to copy/paste the script tag into your funnel. Zellify will load GTM for you when you supply the Container ID.

Connect to Zellify

  1. Go to Dashboard → Settings → Integrations

  2. Find Google Tag Manager

  3. Enter your GTM Container ID (e.g., GTM-XXXXXXX)

  4. Click Save Changes

Event coverage

  • Page views, funnel navigation, and purchase-related events can be forwarded to dataLayer for GTM consumption

  • You can configure GTM tags (e.g., Meta Pixel, GA4) to trigger on these events

Troubleshooting

Container not loading

  • Ensure you have published at least one GTM version

  • Verify the Container ID is correct and saved in Zellify

Tags not firing

  • Use GTM Preview/Debug mode to confirm triggers

  • Ensure your tag triggers match the dataLayer events you expect

Duplicate tracking

  • Remove any hard-coded tracking scripts in custom code when using GTM

Slow page loading

  • Prefer event-based triggers over page-load where possible

  • Throttle heavy tags and avoid blocking scripts
