Odoo Google Tag Manager Enhanced Conversions

Before adding the JS script to your website, first obtain the identifier. To do this, log in to your Google Tag Manager account and copy the Container ID:

After installing the app, go to the website settings and, in the Enhanced Website Tracking section, enable the Activate Tracking option. To test your website tracking and view tracked events in the browser console, also temporarily activate the Debug Logging feature:

If you use Odoo's built-in Google Analytics feature, disable it and transfer the identifier to a new tracking service.

The module is compatible with the Odoo Google Consent Mode solution, which allows managing cookie consent and updating consent states by sending them to Google.

The module allows you to track e-commerce events on your website and send them to Google along with product information and user-provided data. Additionally, you can store this data in internal Odoo logs for website analysis and monitoring. These features are implemented at the tracking service level. Add and configure a tracking service for your Odoo website.

Adding a Tracking Service

Go to the Website - Configuration - Tracking - Services menu and click New to add a new tracking service.

Firstly, fill in the following fields in the new tracking service:

• Specify a Website (if using multiple websites)
• Select Google Tag Manager as the service Type
• Paste your Container ID into the Key field

Then, specify the type of product identifier and product category sent to Google Tag Manager.

If products have attributes and variants, choose Product Variant ID in the Item Type field; otherwise, select Product Template ID.

Select the desired Category Type: an eCommerce Public Category or an internal Product Category.

The next option is the Lead Value on the Options tab.

This field represents the monetary value of a lead generation, based on estimated evaluations.

Tracking Logs

The module includes an internal logging feature. To activate it, enable the Internal Logs option.

To view logs, go to the Website - Configuration - Tracking - Logs menu or click the Logs button at the top of the form.

Custom Event Tracking in Odoo

Another GTM-related feature is the ability to configure custom events in Odoo. In the Custom Events section of the tracking service, you can add a custom event and link it to one of the Odoo tracking events.

Enhanced conversions help optimize your advertisements by providing Google with additional user data. Open the Advanced Matching tab and click Allow Enhanced Conversions, which enables all available options for this tracking service.

User data is sent securely, as it is hashed in accordance with Google's requirements.

Use the Sale Order Partner value as the Customer Data Source because it provides more user details when guest checkouts are allowed without registration:

The module includes additional settings available in Developer Mode.

Product Identifier

The module uses the Product ID field as a unique product identifier. To use a different value, specify another product field containing the desired identifier on the Technical tab:

The specified product field should provide non-empty values and remain unique for each product. Otherwise, the tracking data for this product becomes unusable.

Purchase on Portal

To track portal purchases, enable the Track Purchase on Portal option:

Exclude Delivery

The next available setting for tracking services is Exclude Delivery. When enabled, the service excludes delivery lines from sales orders in tracking data transmissions:

Exclude Rewards

To exclude reward order lines from tracking data, enable the Exclude Reward option:

Add to Cart

By default, the module tracks the actual addition of a product to the cart. To track the event upon clicking the button without waiting for the actual addition to the cart, perform the following steps:

• Navigate to Website — Configuration — Websites
• Open the website on the Enhanced Tracking tab
• Enable the Add to Cart on Click option

Tracking the actual addition might fail if third-party modules modify the logic. In this case, this option allows for event tracking by binding it to button selectors used in native Odoo website templates.

Purchase

To track purchases only after a successful payment transaction, enable the Track Confirmed Purchases only option:

This option only affects the event transmission through the tracking service; the internal log records the event regardless.

If business logic considers an order with a Pending payment status as a purchase, enable the Track Pending Purchases too option as well.

To test the GTM tracking script, use Google Tag Assistant. Click Preview.

Then enter your Odoo website URL and click Connect.

For testing, log out of Odoo or use a different browser, as website tracking does not work for internal Odoo users.

Perform a few eCommerce actions on your Odoo website and review the report in Google Tag Assistant.

Google First-party Mode allows configuring Google tags on your Odoo website to load scripts from your tagging servers or CDN instead of Google's:

The app allows specifying a custom URL for Google Tag Serving. Open the website settings and, in the Tracking and SEO section, change the Tag Serving URL:

After saving the settings, sign out of Odoo and open the page source of your website to review the result:

To restore the default Google tag URL, click the button on the right:

Odoo-side settings alone are insufficient to implement first-party mode. The custom URL must also be configured separately. The configuration methods are described in our blog post: https://garazd.biz/blog/odoo-1/odoo-google-tag-gateway-with-cloudflare-57.
