DATA FLAKES / MASTER KIT
Conversion Tracking & Data Layer
From the measurement plan to a tested go-live.
DATALAYER SPECIFICATION
Event Parameter Type
purchase transaction_id string
generate_lead form_id string
dataLayer.push({ event: “purchase” });
Your campaigns are optimizing for numbers that aren't accurate.
A form tracks a conversion even if the submission fails. The order confirmation counts every refresh as a new purchase. GA4 and Google Ads show conflicting figures, and nobody knows which is accurate. The result: Google Ads optimizes based on the wrong signals, and your budget follows suit.
What counts is the click, not the success.
The same purchase appears twice in the report.
The development team doesn't know exactly what to push into the dataLayer.
Testing is done briefly in the preview, not systematically.
A clear path from plan to test.
The kit gives you a step-by-step process to follow: first define what counts as success, then specify the data for development, then implement it in GTM, and finally test every case. Each step includes a template, and every claim is backed by official Google documentation.
