GA4 and GTM Tracking Evidence Checker
Inspect tracking declarations in supplied HTML. Separate installed-tag evidence from the conversion and revenue joins that still need verification.
Public attribution evidence
Identify supplied tag/configuration evidence and the checks it cannot establish.
A tag in HTML does not prove an event was processed or linked to revenue.
Add your evidence
Pasted HTML is parsed as text. It is never inserted into this page or executed. Remove secrets and private customer records before using it.
Start with what you know.
Supply the HTML or evidence you collected, then inspect it here. This tool does not visit a URL or verify live platform behavior.
- Use the result without an email gate.
- Keep source observations separate from assumptions.
- Export only when you are ready to share the contents.
Calculations and pasted-evidence analysis run in this browser. Saving is optional.
Keep the work. Control the sharing.
JSON files include your inputs. CSV and copied briefs include results that may be sensitive. A copied tool link opens this tool without your inputs or result.
Finding a tag is the beginning of a measurement review
Marketing, analytics and CRM reports can disagree even when a tracking script is present. A useful audit distinguishes the declaration, the browser event, platform receipt and the eventual business record. A public-page checker cannot collapse those stages into a claim that attribution works.
Method and assumptions
Paste HTML from the page you want to inspect. The tool identifies recognizable tracking declarations and IDs, lists what was observed, and provides the next verification questions. Supplied text does not establish whether scripts executed, consent allowed a request, the event reached GA4 or a CRM record retained its acquisition source.
An illustrative example
A GA4 measurement ID in a script is evidence of that declaration in the supplied HTML. To validate a lead event, inspect an authorized browser run, check the intended event and consent state, confirm platform receipt, and reconcile the same logical lead with its CRM source. Repeating a tag in source can also have innocent explanations; investigate before calling it duplicate measurement.
Turn the result into a useful next step
Start with the conversion that matters: qualified lead, demo, purchase or signup. Record the expected event, its trigger, source fields and downstream owner. Use the output to assign the missing checks. I personally build tracking, funnel models and warehouse joins that connect marketing activity with business outcomes.
What the result can establish
The checker does not authenticate to GA4, GTM, an ad account or your CRM. It does not submit a form, bypass consent, inspect runtime network traffic or certify revenue attribution. No detected tag means only that it was not found in the supplied text.
Questions before you use the result
Does an installed GA4 tag prove a conversion is tracked?
No. You still need event execution, consent, platform processing and business-record evidence for the intended conversion.
Does this log into my analytics accounts?
No. This version analyzes your supplied HTML and gives an evidence-based verification checklist.
Can it prove that duplicate events are firing?
No. Repeated declarations can be worth investigating, but runtime event evidence is needed before diagnosing duplicate measurement.
What should I verify after using it?
Check the intended event in an authorized browser session, its consent conditions, analytics receipt, CRM identity and acquisition-source fields.
Do I need to leave my email to use the result?
No. The core tool works without an email gate. Contacting me about an engagement is an optional next step.
Who delivers the consulting work?
I do. I personally lead and deliver the agreed work. Your business retains its own responsibilities and access approvals; the scope is agreed with me directly.
