The ten Chrome extensions I use every week to debug Google Tag Manager, GA4, Enhanced Conversions, ad pixels and Shopify custom pixels, with install links for each one.

GA4 has no AI channel, so visits from ChatGPT, Perplexity and Gemini hide inside Referral and Direct. Here is how to build a report that shows them, and what the numbers really mean.

Unassigned traffic went from 24 percent to over half, and GA4 revenue fell off a cliff. The store had not lost a single sale. Here are the three tracking faults behind it.

You do not need to write a form listener from scratch. Here is where to get tested code for almost any form platform, and how to wire it into GTM.

HubSpot forms sit in an iframe, so normal form tracking cannot see them. This listener solves that, and gives you the submitted field values too.

Contact Form 7 fires a DOM event only when the mail actually sends. Here is how to turn that into a clean conversion in GA4, Google Ads and Meta.

Gravity Forms can confirm without a page reload, which breaks page based tracking. Here is the listener that catches it, and the setting it depends on.

Elementor forms submit over AJAX, so there is no thank you page to track. Here is the listener, and how to work around its one limitation.

Ninja Forms returns a response object with the form ID in it. Here is how to catch it and send a clean conversion to your ad platforms.

Formidable fires a completion event you can listen for. Here is the listener, the form ID it captures, and how to use both in GTM.

WS Form gives you three separate events, including failed submissions. Here is what each one means and which one should be your conversion.

Webflow swaps in a success message instead of loading a new page. Here is the listener, plus an honest look at what it does and does not tell you.
