The Challenge
What was already failing
The ads reported a win the CRM could not find. Spend rose, the landing page disagreed with the offer, and the meeting started with two versions of the same lead.
The Solution
Fix the event, refuse a lead that is not a lead, then scale only what the ledger recognizes.
01 // edge
Events at the edge
Server-side conversion lands even when the browser will not. The click and the CRM share an identifier.

Lead guard
A form is not a lead until it matches the definition finance already signed. The rest stays out of the report.

The page that pays
The landing page repeats the ad. Tests change one line, and the return is visible the same week.

Key Capabilities
What the system is trusted to do
01
Events the browser cannot drop
Server-side conversion keeps the sale when cookies and blockers do not.
02
One definition of a lead
The report and the CRM name the same person. Vanity rows never reach the board.
03
A page that matches the ad
Creative and the landing line are tested together, then the losers are turned off.
