One demo submission, one GA4 event, and a matching CRM lead

Client work. The checks were recorded on 11–12 August 2026, and I have left out the client's identifiers and the original private screenshots.

What the client wanted

A visitor should reach the demo form through a stable address, and a successful submission should produce exactly one lead event with a matching CRM record — not a click event that fires whether or not anything was sent.

What was wrong

• The homepage demo buttons used popup or hash-based navigation, so the demo had no address of its own and could not be linked to, shared or measured.
• There was no permanent demo destination.
• The conversion had to be tied to successful form completion and then reconciled with the CRM.

What I changed

• Created a permanent /demo/ destination.
• Changed the homepage demo buttons to ordinary links to /demo/.
• Gated the generate_lead event on form success rather than on the click.

What I measured

Page or check	What needed attention	Required result	What was observed
Homepage demo links	Popup or hash-based navigation	Normal links to /demo/	Live output matched the tested deployment on 12 August
Successful demo submission	Tracking tied to form success	One generate_lead event per successful submission	One controlled submission produced one outbound GA4 event on 11 August
CRM lead	The test submission reconciled with the CRM	A corresponding HubSpot record	Client confirmed the matching record on 11 August

What it doesn't prove

The result applies to the controlled demo submission and the checked deployment. It does not claim conversion lift, revenue growth or verified trial sign-ups.
