Google Marketing Platform for Gatsby

Easily add these GMP products in a cohesive way to your Gatsby site:

• Google Tag Manager
• Google Analytics
• Google Optimize

The installation is based on Google's recommendations and best practices.

What This Does

This provides the ability to configure the Google Marketing Platform base tools, including Google Analytics, Google Optimize, and Google Tag Manager.

This plugin also allows the ability to preset dataLayer variables. This is useful in cases where you need GA, configured within GTM, to fire with particular variables on the initial pageview, such as dynamically setting your Google Analytics Property ID, instead of requiring to maintain it in multiple locations.

What this does NOT do

This will not provide any functionality around specific tracking or conversion tags. These responsibilities should be handled in Google Tag Manager.

Getting Started

Install

yarn add gatsby-plugin-google-marketing-platform

or

npm install gatsby-plugin-google-marketing-platform

Basic Setup

// In your gatsby-config.js
plugins: [
  {
    resolve: 'gatsby-plugin-google-marketing-platform',
    options: {
      dataLayer: {
        gaPropertyId: '[Google Analytics ID]',
      },
      tagmanager: {
        id: '[Google Tag Manager ID]'
      },
      analytics: {
        id: '[Google Analytics ID]'
      }
    },
  }
]

Configuration

Data Layer

The dataLayer key is a freeform object that will allow you to pass data through to the globally available dataLayer array that Google Tag Manager utilizes to store and watch data. There is no set functionality for this, but you can see below for some usage examples.

Examples

Tag Manager

Configuration specifics for Google Tag Manager.

Analytics

Configuration specifics for Google Analytics.

Optimize

Configuration specifics for Google Optimize.

Activation Method

By default, this plugin doesn't push any activation events to Google Tag Manager for single page apps. The activateOn property allows configuration to provide different methods of activation.

Activation events refers to Google's way of handling re-activating Optimize on DOM change.

          gtm_cookies_win: 'x'

      },
