Is GCLID Only for Google Ads?

Posted

Yes, the GCLID (Google Click Identifier) is a unique tracking parameter automatically appended to URLs from Google Ads clicks when auto-tagging is enabled.

Purpose of the GCLID

GCLID allows systems like Google Analytics or CRMs to attribute specific sessions and conversions back to individual Google Ads clicks. It contains encoded data about the ad, campaign, keyword, and more.

Other Platforms Use Different Parameters

While GCLID is exclusive to Google Ads, other platforms have their own identifiers:

  • FBCLID – used by Facebook Ads
  • MSCLKID – used by Microsoft Ads (Bing)
  • TTCLID – used by TikTok Ads

GCLID Requires Auto-Tagging

To use GCLID:

  • Make sure Auto-Tagging is enabled in Google Ads
  • Ensure your website and analytics platform can store and read the parameter
  • Confirm redirects or CMS plugins don’t strip it from URLs
