What is the Google Click Identifier (GCLID)
The Google Click Identifier (GCLID), also known as the Google Click ID, is a specific parameter included in the URL when a user clicks on an ad. Its purpose is to identify the campaign and various click characteristics, aiding in ad tracking and attribution.
In Google Ads, this functionality is activated by enabling the auto-tagging setting. The GCLID is essential for tracking website conversions in Google Ads and establishing connections between Google Ads and Google Analytics.
Additionally, it can be used alongside offline conversion tracking and other features.
