Lesson 5 of 7
Enhanced Conversions For Leads
Sometimes you do not have a click id, the cookie expired, or the lead came in through a channel that did not carry one. Enhanced Conversions for Leads matches on the first-party contact data the user submitted instead.
How it works
- The form submit captures the user's email (and optionally phone).
- That data is hashed in the browser before it is sent.
- When you upload the offline conversion keyed on the same hashed email, Google matches it to the click.
Emailsubmitted→Hashedin browser→Matchedto click
Because the email is hashed before leaving the browser, the raw address is not exposed in the process, which is what makes this a privacy-aware alternative to the click id.
Key takeaway
No click id? Match on hashed email or phone instead. It is set up through GTM with user-provided data, hashed before sending.
