UTM Tracker plugin for Craft CMS 3, 4 and 5

Get landing page location and query parameters when the user lands on the site. Keeps them in the session for use in forms or other usage in twig variables.

Requirements

This plugin requires Craft CMS 3.7, 4 or 5.

Installation

To install the plugin, follow these instructions.

1. Open your terminal and go to your Craft project:

    cd /path/to/project
   

2. Then tell Composer to load the plugin:

    composer require digitalpulsebe/craft-utm-tracker
   

   Or when using Craft 4, use version 2:

    composer require digitalpulsebe/craft-utm-tracker:^2.0.0
   

   Or when using Craft 3, use version 1:

    composer require digitalpulsebe/craft-utm-tracker:^1.0.0
   

3. In the Control Panel, go to Settings → Plugins and click the “Install” button for UTM Tracker.

Configuring UTM Tracker

Configure options in the Craft control panel or create a file in config/utm-tracker.php as a copy of config.php.

By default, you should keep track of these UTM tags:

• utm_source (Campaign Source, example: Google)
• utm_medium (Campaign Medium, example: email)
• utm_campaign (Campaign Name, example: xmas2022)
• utm_term (Campaign Term, example: christmas+presents)
• utm_content (Campaign Content, example: version+A)

Also, the landing URL and referrer URL are tracked when the session is created.

Other configuration (config/utm-tracker.php) options are:

• 'cookieName': the name of the cookie (when used)
• 'cookieLifetime': lifetime of the cookie in seconds (when used)

Usage

Available twig variables:

{{ craft.utmTracker.landingUrl }}
  {# example: https://example.com/pages/detail #}
  
{{ craft.utmTracker.absoluteLandingUrl }}
  {# with query parameters, example: https://example.com/pages/detail?param=1 #}
  
{{ craft.utmTracker.referrerUrl }} 
  {# example: https://google.com/ #}
  
{{ craft.utmTracker.tag('utm_campaign') }}
  {# one tag by key #}

{{ craft.utmTracker.tags|json_encode }}
  {# all tags in an array #}

Using UTM Tracker in combination with Formie

1. Drag a custom field 'Tracked Field' on your form
2. Name your field whatever you want, select the source in the dropdown
3. When selecting a Query Parameter (tag) as a source, select the key from the list. It is the same list as the tags you defined in the settings of this app.

Using UTM Tracker in combination with Freeform

1. Create hidden fields and add them to your form
2. Render tag with default value filled from the available variable properties

example:

{{ form.render({
   'storedValues': {
      'myHiddenField': craft.utmTracker.landingUrl
   }
}) }}

Tracking in combination with full page caching

When the pages are cached entirely (using Blitz, Varnish...) there is no way for Craft CMS to pick up the traffic. You will need to send and retrieve data using javascript asynchronously. But beware: it might increase server load. If your application has very high traffic, consider a javascript only solution.

Sending data to the backend

Put this in your twig layout template file:

{{ craft.utmTracker.reportScript() }}

It will make a POST call to the Craft CMS backend to avoid caching.

Retrieving data

To use the data on cached pages you will need to retrieve it from the api.

Make a call to https://example.com/actions/utm-tracker/api/data and you will get this json

{
    "data": {
        "queryParameters": {
          "utm_campaign": "campaign"
        },
        "absoluteLandingUrl": "https://example.com/landing-page?utm_campaign=campaign",
        "landingUrl": "https://example.com/landing-page",
        "referrerUrl": null
    }
}

Notice: tracking user data

Don't forget to notify the user details are tracked to comply to the GDPR rules. When you select the cookie storage method an extra cookie is created. The name and lifetime of the cookie is configurable in the config file. By default, the key is 'utm_tracking_parameters'.
