What is a GTM container builder?

A GTM container builder generates a Google Tag Manager container as a JSON file you import into GTM, with the tags, triggers, and variables already wired together. TagManagerBuilder does this for free: you pick your website platform, tracking tools, and events, enter your IDs, and download the file.

Which website platforms does TagManagerBuilder support?

It supports WooCommerce, WordPress, BigCommerce for WordPress, and GoHighLevel websites and funnels. Each platform has its own event list, such as Purchase and Add to Cart for stores, or form, survey, and booking conversions for lead-generation sites.

Can I use Google Tag Manager with GoHighLevel?

Yes. Paste your GTM snippet into the Tracking Code (Header) setting of your GoHighLevel website or funnel, then import a container built with this tool. It adds GA4, Google Ads, Meta, TikTok, and Pinterest tags for GoHighLevel form submissions, survey completions, calendar bookings, and thank-you page views.

How do I track GoHighLevel form submissions with GTM?

GoHighLevel forms load in iframes, which GTM's built-in form trigger cannot see. The generated container includes a bridge tag that listens for the message HighLevel's embed sends on submit and pushes a dataLayer event, plus a thank-you page trigger as a dependable fallback. Confirm the event once in GTM Preview after importing.

Which tracking tools can I set up?

GA4, Google Ads, Meta Pixel, TikTok Pixel, Pinterest Tag, LinkedIn Insight Tag, Microsoft UET, and X Pixel, in any combination. Each tool gets the tags and triggers that match the events you select.

Is TagManagerBuilder really free?

Yes. Every platform, tool, and event is free with no account, no trial, and no locked tiers. The site is supported by display advertising, and paid done-for-you services are optional.

Do I need to know how to code?

No. You choose options in a wizard and import the downloaded file into Google Tag Manager. Some events on WooCommerce, BigCommerce, and WordPress need your site to push a dataLayer event, and each guide says exactly which ones.

Is TagManagerBuilder affiliated with Google, HighLevel, WooCommerce, or BigCommerce?

No. It is an independent tool and is not affiliated with, endorsed by, or sponsored by Google, HighLevel (GoHighLevel), Automattic, WooCommerce, or BigCommerce. Product names are used only to describe what each guide covers.

Cross-Domain Tracking for WooCommerce

Quick answer: The wizard's Cross-Domain Tracking checkbox doesn't currently modify your container. To track a visitor across two domains correctly in GA4, add both domains to the GA4 Configuration tag's "Configure your domains" field directly in GTM - this keeps a single session ID as visitors move between them.

Cross-domain tracking matters whenever a customer's journey crosses domains you own - a storefront on one domain and a hosted checkout, payment gateway, or headless frontend on another. Without it, GA4 treats the visitor as two separate sessions and attributes the purchase to a new, direct-traffic session instead of the original marketing source.

Not yet automated here. This wizard checkbox doesn't change the generated container yet. Here's the manual GTM setup, which only takes a couple of minutes.

Manual setup steps

In GTM, open your GA4 Configuration tag.
Under Tag Settings, find "Configure your domains" and add every domain the customer journey spans (e.g. yourstore.com and checkout.yourpaymentprovider.com).
Publish the container, then click any outbound link between the two domains in Preview mode and confirm a _gl linker parameter is appended to the URL.
Complete a full test purchase across both domains and confirm in GA4's real-time report that it registers as one session, not two.

Note this configures the linker parameter inside GTM only - it doesn't change server-side session or cookie behavior on either domain, which is outside what a GTM container alone can control.

Frequently asked questions

Do I need this if my whole store is on one domain?

No - cross-domain tracking only matters when the customer journey genuinely spans more than one domain you control. A single-domain WooCommerce store doesn't need it.

What's the _gl parameter I see appended to links?

That's the linker parameter GA4 uses to pass a client/session identifier between your configured domains, so the second domain recognizes it as the same visit rather than starting a new session.

Does this affect Meta, TikTok, or other platform tags too?

No - the domain linking behavior described here is specific to GA4's native tag settings. Other platforms handle cross-domain identity differently, typically through their own pixel/cookie matching.
