Matomo & CookieTractor

Matomo is an analytics tool and tag manager that can be run either in the cloud or on its own server. This makes Matomo a popular choice for websites that want to have complete control over the data that is collected about the site's visitors.

Matomo mainly consists of two parts:

• The analytics tool, comparable to Google Analytics
• Matomo Tag Manager, comparable to Google Tag Manager

Those who are familiar with Google tools will recognize the setup.

Setup CookieTractor with Matomo Tag Manager

CookieTractor integrates with Matomo Tag Manager in an easy way. To control which of your scripts belong to the respective cookie category, the scripts need to be categorized. CookieTractor has built-in support for Matomo and will trigger events based on the visitor's consent settings. To use these inside Matomo, we need to create "Triggers" for any "Tags" dependent on the consent settings.

Go to "Triggers" in Matomo Tag Manager and add new Triggers by clicking "Create new trigger". Create the following Triggers:

Name	Trigger Type	Event Name
Consent - Necessary (All Pages)	Custom Event	cookies_necessary
Consent - Functional (All Pages)	Custom Event	cookies_functional
Consent - Statistical (All Pages)	Custom Event	cookies_statistical
Consent - Marketing (All Pages)	Custom Event	cookies_marketing

Now, update any Tags that require consent from your users to be triggered by any of these Triggers. This is done by clicking "Edit tag" and then change Trigger under "Execute this tag when any of these triggers are triggered.".

If you need to listen to events when a user revokes a consent, you can create the following Triggers and use them on your Tags:

Name	Trigger Type	Event Name
Consent Revoked - Statistical (All Pages)	Custom Event	cookies_revoked_statistical
Consent Revoked - Marketing (All Pages)	Custom Event	cookies_revoked_marketing

Variables to check for consent

In some cases, one might need to check if a visitor has consented to a specific type of cookie using "Conditions" for a Tag or Trigger. To make it easier to access this information, we can add Variables for this under "Variables" in the interface. 

Here are some examples of Variables that might be usefull:

CookieConsent_AllowFunctional

Name: CookieConsent_AllowFunctional
Type: Custom Javascript
JavaScript Function:
function(){
  return cookieTractor.consent.contains('functional');
}

CookieConsent_AllowStatistical

Name: CookieConsent_AllowStatistical
Type: Custom Javascript
JavaScript Function:
function(){
  return cookieTractor.consent.contains('statistical');
}

CookieConsent_AllowMarketing

Name: CookieConsent_AllowMarketing
Type: Custom Javascript
JavaScript Function:
function(){
  return cookieTractor.consent.contains('marketing');
}
