- They should turn off auto-tagging in all your Google Ads accounts that are enabled for sitewide tagging.
- They should make sure Google Click Identifier (GCLID) still works if using click trackers in the URL.
- They should make sure the tag still works by loading it within another tracking tag, like Floodlight.
The Correct Answer is: They should make sure Google Click Identifier (GCLID) still works if using click trackers in the URL.
Explanation: Before implementing sitewide tagging, a marketer should first verify that the Google Click Identifier (GCLID) is operational, particularly if using click trackers in the URL. This process is integral because GCLID helps track the unique identifier for a user or the ad click that led the user to your site. When an ad is clicked, the GCLID and AUID (Advertiser user ID) parameters are automatically added to your landing page, provided you have auto-tagging enabled in your Google Ads account. These parameters are stored in first-party cookies deployed by sitewide tagging solutions, facilitating accurate conversion measurements when identical tags are fired on the conversion page.
