To obtain a tag ID in Google Ads, log in to your account and navigate to Tools — Data Manager. Open your Google tag and copy the 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.

This app includes the Google Consent Mode V2 implementation. You can add default values for Google consents and manage them for different regions and countries. After activation, Google Consent Mode works with the standard Odoo cookie bar, granting or denying consent for Google.

To learn how to configure it, visit this page: Odoo Google Consent Mode

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 Ads as the service Type
• Paste your Tag ID into the Key field

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

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.

The list of internal tracking events.

Conversion tracking in Google Ads helps you evaluate the effectiveness of your advertising and shows what actions customers take after clicking an ad.

To start tracking conversions, create a conversion action in Google Ads and a corresponding custom event in Odoo.

Google Ads Conversions

To create a new conversion action in Google Ads, complete the following steps.

In your Google Ads account, navigate to Goals — Summary and click Create conversion action.

Select Conversions on a website as the data source for measuring conversions.

Paste your Odoo website URL into the field and click Scan.

After scanning, select Google Tag as the data source, click Done, and then click Save and Continue.

Select the goal category for this conversion action.

Select the Manually with Code option.

Fill in the conversion action details in the Conversion Settings section:

• Enter the conversion name.
• Select Use different values for each conversion to record specific values for each event. This value is passed from Odoo and equals the product price or sales order total depending on the tracking event type.
• Enable Enhanced Conversions.
• Configure the remaining parameters as needed, or keep the default values.

For detailed instructions on setting up conversion tracking, refer to the official Google Ads documentation: https://support.google.com/google-ads/answer/12216424.

Click Done, then click Save and Continue.

Next, click See event snippet to obtain the conversion name and destination ID.

Copy the conversion action name and the value of the send_to parameter.

Custom Event Tracking in Odoo

To create a custom event in Odoo for tracking conversions:

• 01
  Open the Google Ads tracking service on the Options tab
• 02
  Select the event type configured as the goal for your conversion action in Google Ads
• 03
  Paste the copied conversion action name and the send_to parameter value

If you want to track this conversion exclusively for remarketing, enable the Remarketing Only option.

For more details on setting up remarketing in Google Ads, refer to this link: https://support.google.com/tagmanager/answer/6106960.

You can add multiple custom events for Google Ads conversions and link them to standard Odoo e-Commerce tracking events:

Currently, you can add only one custom event per event type.

After linking these events, you can see their firing in internal logs.

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

User data is sent in a protected way, as it is hashed in accordance with Google 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:

To ensure compatibility with this module, select the Google Tag method in the Google Ads Enhanced Conversions settings.

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.

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.

You can verify how tracking event data is sent using Google Tag Assistant. Open the conversion list in Google Ads. If the conversion status is not Active, click Troubleshoot to connect to Google Tag Assistant.

In the following pop-up windows, select Continue and enter your Odoo website URL.

Click Connect and Tag Assistant opens your website, where you can test the conversion action.

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