[FEATURE] Support for Google Tag Manager

[elkmod]

Description

This is a feature proposal, so we can use this to collect and discuss requirements, implementation and functionalities of such an integration.

Google Tag Manager allows for enhanced tracking of user interactions/activities on eCommerce websites. These impressions include:

• Product Impressions
• Product Clicks
• Product Detail Impressions
• Add / Remove from Cart
• Promotion Impressions
• Promotion Clicks
• Checkout
• Purchases
• Refunds

Each interaction has to be provided along with a set of parameters, giving more detailed insight about the activity performed by the user. These parameters (along with meta information about the event) are pushed into the a dataLayer variable which is used to send the corresponding tracking event to GTM.

More information can be found here:

• GTM Developer Guide
• GTM Enhance Ecommerce

Ideas

There is a nuxt plugin which adds basic GTM functionality and configuration to any nuxt project and publishes the data layer as a property of your Vue instance - @nuxtjs/gtm

Acceptance criteria

• I optionally can configure Google Tag Manager as a Tool for User Tracking
• The most significant events as well as their according "Enhanced Ecommerce" parameters are provided
