What is google analytics and how its works

Google Analytics is a web analytics service provided by Google that allows website owners, businesses, and marketers to track and analyze the performance of their websites and digital marketing efforts. It provides valuable insights into visitor behavior, traffic sources, and website performance, helping users make informed decisions to improve their online presence.
Integrating Google Analytics with a Nuxt.js 2.x application involves adding the Google Analytics tracking code to your project. Here's a step-by-step guide on how to do it:
1.Create a Google Analytics Account: If you don't already have a Google Analytics account, sign up for one at Google Analytics. After creating an account, you'll need to set up a property to track your website.
2.Generate a Tracking ID: Once you've set up a property in Google Analytics, you will be provided with a unique Tracking ID (e.g., UA-XXXXXXXXX-X). Make a note of this ID, as you'll need it for integration.
3.Install the Vue Analytics Package: To integrate Google Analytics with your Nuxt.js 2.x application, you can use the vue-analytics package. Install it by running the following command in your project directory:
      npm install vue-analytics

  
4.Create a Plugin for Google Analytics: Create a new plugin file (e.g., google-analytics.js) in your Nuxt.js project's plugins directory. In this file, you can configure Google Analytics with your Tracking ID:
      // plugins/google-analytics.js

import Vue from 'vue'
import VueAnalytics from 'vue-analytics'

Vue.use(VueAnalytics, {
  id: 'UA-XXXXXXXXX-X', // Replace with your Tracking ID
  debug: {
    enabled: process.env.NODE_ENV === 'development',
    trace: true,
    sendHitTask: process.env.NODE_ENV === 'production'
  }
})

  
Replace 'UA-XXXXXXXXX-X' with your actual Tracking ID.
5.Register the Plugin: In your Nuxt.js configuration (usually in nuxt.config.js), add the newly created plugin to the plugins section:
      // nuxt.config.js

export default {
  // ...
  plugins: [
    { src: '~/plugins/google-analytics', ssr: false }
  ],
  // ...
}

  
Setting ssr: false ensures that Google Analytics doesn't run on the server-side (SSR) during server rendering.
6. Add Script Tags for Google Analytics in HTML: In your Nuxt.js project's HTML template (usually in layouts/default.vue or another layout file), add the necessary script tags for Google Analytics just before the closing </body> tag:
      <!-- layouts/default.vue -->

<script async src="<https://www.googletagmanager.com/gtag/js?id=UA-XXXXXXXXX-X>"></script>

  
Be sure to replace 'UA-XXXXXXXXX-X' with your actual Tracking ID.
7.Using Google Analytics in Your Components: You can now use Google Analytics in your Nuxt.js components. To track page views or events, you can use the $ga object, which is injected into your components by the vue-analytics package:
You can use this to track page views and custom events as needed.
      // In a Nuxt.js component

this.$ga.page('Page Title')
this.$ga.event('Category', 'Action', 'Label', Value)

  
8.Testing: During development, Google Analytics will only run in debug mode if process.env.NODE_ENV is 'development'. In production, it will send actual data to your Google Analytics account. Be sure to thoroughly test your implementation before deploying it to a production environment.
After following these steps, Google Analytics will be integrated into your Nuxt.js 2.x application, allowing you to track user interactions and gather valuable insights about your website's performance and user behavior.
