Setting up offline conversions requires using which identifier?

• A. The GCLID is a user email address to track identity
• B. The GCLID is a cookie on the site
• C. The GCLID is a parameter in the ad's query like utm_source
• D. The GCLID is a randomly generated string appended to a URL when an ad is clicked.

Answer: (D)

Offline conversions rely on a unique identifier that ties the conversion back to the specific ad click. This identifier is the Google Click Identifier, or GCLID. When a user clicks a Google ad, Google Ads appends a GCLID to the destination URL as a query parameter. That string is randomly generated for each click, so you can capture it (for example in your site, CRM, or cookies) and later send it back to Google with the offline conversion data to attribute the action to the exact click. The GCLID is not a user email and isn't inherently a cookie; it’s specifically that randomly generated string appended to the URL at click time, which is what enables precise matching for offline conversions.
