OFFLINE CONVERSION IMPORT REVIEW Internal review checklist, not a Google upload format or automatic submission. IDENTIFY THE PATH Classic click import / enhanced conversions for leads / phone-call import: Connector and API/product version; current supported access model: Target advertising account / actual conversion-owning account / manager context: Exact destination action resource or identifier; intended qualified/converted stage: Current API access restriction checked if applicable; no credentials in this record: FREEZE THE COMPARISON Business outcome cohort and qualification rule / source export timestamp: Actual business conversion time with UTC offset; source/account time zones: Original interaction period when known / upload time / review cutoff: Conversions versus All conversions; standard versus by-conversion-time columns: Selected campaign/action filters / goal membership / counting option: Aggregate reports cannot identify which individual CRM rows were attributed. TRACE THE ATTEMPT Opaque internal outcome ID and stable deduplication identity: Captured click identifiers when available; provenance, not reconstructed values: Required permitted first-party fields and path-specific formatting verified: Consent signals preserved; do not paste customer fields into public troubleshooting: Request/job identifier, original input row reference, destination and submission time: Per-row result/error/warning; transport success versus final processing evidence: Later attempt status, actual retry policy and destination diagnostics: Do not invent a new conversion time or identity to force an old upload through. INVESTIGATE THE GAP Explicit failed rows to repair: Pending or incomplete results to revisit at a stated cutoff: Distinct business outcomes with documented accepted results: Repeated attempt rows kept separate from unique outcomes: Missing/unavailable matching data or unsupported scope: Reporting date basis, attribution scope, processing and counting reviewed: Unresolved facts and owner; avoid labelling the gap as fraud or lost customers: CHANGE AND VERIFY Specific fix, affected connector/action, owner and rollback: One supported test outcome followed through row results and diagnostics: Before/after export dates, remaining unresolved issues and processing review time: Actual selected campaign goals and custom-goal membership checked separately: Billing and visitor protection are separate from import success and attribution.
