Lead tracking, step by step

A live demo of GTM-first lead tracking: you click, you fill in a form, and you watch each event leave this page in real time.

Click here to start

One button. Clicking it pushes a demo_started event to the dataLayer — the same way any real click on your site would.

Fill out this form

A normal-looking lead form. When you submit, exactly this will be pushed to the dataLayer:

next 
dataLayer.push({
  event:          "generate_lead",
  demo_type:      "leadgen",
  lead_company:   "Northwind Logistics",  // what you type below
  lead_id:        "L_1753861142",         // generated on submit
  form_id:        "leadgen_demo",
  lead_source:    "leadgen_showcase",
  email_provided: true
});

Your email address itself never enters the dataLayer — only the fact that one was given. The company name travels along so you can recognise your own event in the stream.

Demo only. No backend call, no database, no email. Nothing is stored beyond the tracking demo.

Both panels are live and were already recording before you started. Left: the events. Right: the cookies.

Every event this page sends, the instant it happens — the tag manager's own bookkeeping included.
