Cookies bar

Cookies are small text files sent to your device when you visit a website. They are processed and stored by your browser and record visitor information like login details, preferences, and browsing history. Essential cookies are necessary for the website to function, while optional cookies are used to analyze behavior or display ads.

Important

When the Google app or the Meta app is installed, the cookies bar is replaced by the cookie consent banner (Accept all, Reject all, Customize, consent categories, cookie list, and Cookie settings link) and its settings replace the Cookies Bar setting. See Cookie consent.

Data protection laws require notifying visitors about data collection methods and purposes. Cookies bar fulfill this obligation by informing visitors on their first visit and allowing them to decide whether to store all or only essential cookies on their device.

Note

• Cookies bars are required to obtain visitors’ consent for optional cookies only. Consent is not required for essential cookies.

• Odoo is compliant with Google consent mode v2: the consent state is set to denied by default and updated to granted or denied according to the visitor’s choice. In eYssen ERP, the Google consent mode (advanced) module also lets the Google tag load before the choice is made.

Configuration

To add a cookies bar on your website, go to Website ‣ Configuration ‣ Settings and enable Cookies Bar in the Privacy section. This activates Block tracking 3rd-party services by default, including social media, video hosting platforms, and Google services. Click Add domains to the block list to include other external websites. These services remain blocked on your website until visitors accept optional cookies.

Note

Using third-party cookies without a cookies bar does not prevent them from being triggered. Only the presence of a cookie bar and the visitor’s refusal ensure that these cookies are blocked.

Google consent mode (advanced)

With the cookies bar enabled, the standard behavior is to block the Google tag (gtag.js) until the visitor accepts optional cookies, because googletagmanager.com and google-analytics.com are on the block list of third-party services. As a result, the tag only loads on the next page after the visitor accepted. Google Analytics 4 then loses the landing page, the gclid parameter of Google Ads and the referrer of the first page, and the visit is reported as Direct.

The Website: Google consent mode (advanced) module (eyssen_website_consent_mode) fixes this by removing these two domains, and only these two, from the block list.

Set it up

1. Install the module from Apps (search for eyssen_website_consent_mode). It has no setting and no menu.

2. Go to Website ‣ Configuration ‣ Settings, enable Cookies Bar in the Privacy section, and enable Google Analytics in the SEO section with your Measurement ID (see Google Analytics).

3. Click Save.

Important

The module removes the two Google domains from the block list of every website that has a Google Analytics Measurement ID. It only has a visible effect when the cookies bar is enabled with Block tracking 3rd-party services, which is the default. Websites without a Measurement ID keep the standard behavior.

How it behaves

• The Google tag loads on the first page, before the visitor answers the cookies bar. The consent default stays denied for analytics and advertising storage, so Google does not set analytics cookies until the visitor accepts.

• When the visitor accepts or refuses optional cookies, the cookies bar sends the consent update (granted or denied) on the same page, without a reload.

• The landing page, the gclid and the referrer of the first page reach Google Analytics 4.

• If you added googletagmanager.com or google-analytics.com yourself with Add domains to the block list, they stay blocked.

Note

This is Google’s advanced consent mode: while consent is denied, Google may receive cookieless pings from the visitor’s browser. Check that this fits your data protection requirements and mention it in your cookies policy.

Check that it works

Open your website in a private browsing window and open the developer tools of your browser (F12), Network tab.

1. Reload the page, without answering the cookies bar. A request to googletagmanager.com/gtag/js must appear on this first page. Without the module, the script is rendered with the address about:blank and no request is made.

2. Click I agree or Only essentials in the cookies bar. In the browser console, the dataLayer object receives a consent update entry (granted or denied) on the same page, without a reload.

Note

The module has no effect on other trackers: the other third-party services of the block list (social networks, video platforms, Google Maps, etc.) are still blocked until the visitor accepts optional cookies.

Cookies policy

When you enable the cookies bar for your website, Odoo creates the Cookie Policy page (/cookie-policy) containing a list of cookies set by default, with their purpose and examples.
