REDIRECT CLICK-DATA HANDOFF

Test date / owner:
Ad account / campaign / landing-page path (no real click ID):
Browser / device / consent state:
Fresh navigation or reused browser session:
Auto-tagging and linked-property checks:

SYNTHETIC TRANSPORT TEST
Use a mixed-case test marker, not a real ad click.
Starting URL:
Each HTTP hop: status / source host+path / destination host+path:
First hop that loses or alters the test parameter:
GCLID name and complete value unchanged:
UTM names/values / duplicate keys / existing-query handling:
Final document URL:
Client-side redirect or URL-cleanup script after document load:
HTTP trace and browser trace agree / explain difference:

TAG AND STORAGE TEST (separate from query transport)
Actual sitewide Google tag or Conversion Linker setup:
Tag Assistant result under each permitted consent state:
Relevant cookie/storage scope and availability:
Landing host versus conversion host / embedded third-party form:
Required supported cross-domain setup and destination cooperation:
Accepted form / received enquiry / real conversion action:
Report account / property / action / date basis / processing status:
What the synthetic marker cannot prove:

CHANGE AND ACCEPTANCE
Rule owner: CDN / web server / CMS / browser script / external service:
Exact rule to change and reviewed destination host:
Staging result for bare URL and already-tagged URL:
Query encoding, mixed case, multiple parameters and existing-query test:
No redirect loop, duplicate parameter, unexpected host or failed page:
Change date / rollback / cache invalidation if applicable:
Repeated browser and platform-supported verification:
Remaining attribution or business-outcome issue:

Keep real identifiers, cookies and customer details out of shared notes.
Preserving parameters does not establish a recorded conversion or prevent fraud.
