Direct answer: Enhanced conversions for leads uses eligible consented first-party information in a documented protected format to improve matching between leads and later conversions. Configure it only with a clear data flow, current Google requirements, legal basis, accurate CRM events and access controls.
Key takeaways
- It supplements measurement; it does not replace consent.
- Map data from capture to CRM outcome before configuration.
- Use only supported fields and formats.
- Monitor diagnostics and restrict access.
Confirm eligibility and consent
Review Google's current enhanced conversions for leads guidance. Document notice, consent, permitted use and retention with appropriate advisers.
Map the data flow
- Capture permitted first-party information.
- Create a stable CRM lead record.
- Record an eligible conversion outcome.
- Prepare data under current formatting rules.

Security controls
Limit credentials, exports and upload access. Do not place customer information in URLs, analytics parameters or logs beyond operational need.
Validate
Use diagnostics, known test records and cohort reconciliation. Confirm that duplicates, timestamp errors and ineligible data do not distort reports.

Platform interfaces and requirements change, so verify official documentation before implementation. The framework does not promise perfect attribution; it makes evidence, controls and uncertainty visible.
