Context:

Last year we started tracking a few click events on selected Planet 4 sites via Google Tag Manager, often based on the element's IDs or classes. This usually demands an extensive custom setup in Tag Manager and is often less accurate. 

Tracking Methodology (updated)

As suggested by pvincent and sdeshmuk, we can work with data-* attributes instead of dataLayer events. This should facilitate the implementation while also allowing some more flexibility when setting up the events tags in Google Tag Manager. 

The idea is to implement a set of new data attributes with standard values. These will be used later to trigger events and define its category, action and label.

• Example: See image attached for using GTM's dataLayer variable to extract data attributes (gtm.element.dataset.target)
• Useful Links: https://mixedanalytics.com/blog/value-data-attributes-javascript-gtm/

Task: 

• Implement data-attributes on elements:
  • data-ga-category
  • data-ga-action
  • data-ga-label 
• Implement data-attributes with the following standard values: 

  data-ga-category	data-ga-action	data-ga-label
  Search Page	Issue Filter Tag Filter Category Filter Content Filter	[filter name]
  Search Page	Load More Button	[n. results displayed]
  Search Page	Sort By Filter	Most Relevant Most Recent
  Search Page	Search Button	n/a
  Search Results	Title  Call to Action Image Navigation Tag Category Tag	Post Campaign Document Take Action Page

Here's a screenshot linking the design elements with the data-ga-action standard value:

  
 More Information:

• [filter name] = name of the issue / tag / category / content checkbox that was clicked by the user
• [n of search results] = number of search results when the user clicked on the Load More button

Next steps:

1. Julia should create the Google Tag Manager setup in all P4-NRO's containers.  
2. Investigate and communicate with NROs using child themes to apply the same data attributes
