Why Google Ads Conversion Tracking Failed

Google Analytics BCS 2 days ago 25 Views 0 Comments

You may encounter Google Ads Conversion Tracking Failed, such as:

There are several reasons:

Tag Configuration Error

Google Ads conversion tracking relies on the tracking code being correctly placed on the website. If the tag’s Conversion ID or Conversion Label is entered incorrectly, or the code is not correctly placed on the web page, the tag will not fire.

 

Trigger Configuration Error

In Google Tag Manager, conversion tracking tags need to be triggered by triggers. If the trigger conditions are not set correctly, the tag may not be triggered.

 

Consent Mode or Privacy Settings

With stricter enforcement of privacy regulations (such as GDPR), the website’s cookie consent settings may prevent the tracking code from running. If the user does not grant the necessary consent (such as ad_storage, ad_personalization), the conversion tag may be blocked.

If CMP is installed, ensure that the parameters passed are correct when agreeing and the data can be tracked normally.

 

Browser or Ad Blocker

Some browsers (such as Firefox, Brave) or ad blocking extensions may block the execution of Google Ads tracking code, resulting in trigger failure.

Remove unnecessary plugins

 

Content Security Policy(CSP)

Blocked by Content Security Policy, such as:

The solution is to add the following code to the header of all pages:

<meta http-equiv="Content-Security-Policy" content="default-src 'self'; script-src 'self' www.googletagmanager.com www.google-analytics.com; connect-src 'self' www.google-analytics.com; img-src 'self' data: www.googletagmanager.com www.google-analytics.com; style-src 'self'; frame-src 'self' www.googletagmanager.com">

 

Missing Conversion Linker

The Conversion Linker tag is used to store ad click information (such as gclid parameters) in first-party cookies to ensure the accuracy of cross-page or cross-domain tracking. If this tag is missing or configured incorrectly, conversion tracking may fail.

Make sure you have installed the Conversion Linker. Read more : Conversion Linker in Google Tag Manager

 

Cookie Conflict

The cookie _gcl used for Google Ads conversion conflicts and cannot be generated.

The solution is to customize another cookie name
