What is Gclid?

Gclid, also known as a “Google Click ID” or Google Click Identifier,” is a tracking identifier that is generated when someone searches one of your targeted keywords and clicks on your ad. So, every time your ad gets clicked through Google Ads, a Gclid will be added to the end of the link. We have included an example image to show you where the Gclid shows up in a URL.

How to Enable Gclid in your Google Ads Account

Setting up Auto-Tagging for Gclid

To enable Gclid in your Google Ads account, you need to set up auto-tagging. Auto-tagging automatically appends the Gclid parameter to the landing page URLs of your ads. To enable auto-tagging, go to your Google Ads account settings, navigate to the “Tracking” section, and turn on the auto-tagging option.

Linking Google Ads and Google Analytics for Gclid tracking

To track Gclid data more effectively, it is recommended to link your Google Ads and Google Analytics 4 accounts. By linking these accounts, you can access more detailed conversion data and gain deeper insights into the performance of your ad campaigns.

In Google Analytics, click on the “Admin” and you will see a screen with different options. Under “Product Links” you will see an option for “Google Ads Links” and that’s what you want to click.

Why Use Gclid?

In essence, Google Click ID passes information from your Google Ads account to your Google Analytics account automatically, without you having to create multiple, lengthy URLs. Enabling a Gclid will save you time and track the campaign specifics, including costs, cost-per-click, sessions, bounce rate, ad group targeting, keyword targeting, which ad was driving clicks, and conversion data. We have included some example images from a Google search that drives to a Surfside PPC ad campaign.

You can also generate your Gclid in Bing Ads by going to your account settings and enabling auto-tagging in Bing Ads, which will help you track your campaigns in Google Analytics. While the Gclid removes the need for the Google Campaign URL Builder when using Google Ads and Bing; we do recommend still using the builder tool for channels such as Pinterest Ads and Facebook Ads to track your campaigns.
